1e52835a89 armv8/fsl-lsch3: Use correct compatible for serial clock fixup
The serial nodes in the fsl-lsch3 device trees have compatible =
"fsl,ns16550", "ns16550a" -- so don't look for "ns16550".

12eaf31c07 armv8/fsl-lsch3: Update early MMU table
During booting, IFC is mapped to low region. After booting up, IFC is
remapped to high region for larger space. The environmental variables are
also stored at high region. In order to read the variables during booting,
a virtual mapping is required.

Cache was enabled for entire IFC space before. Actually the first two
entries are big enough (4MB) to cover the boot code and environmental
variables. Remove extra entries. Move OCRAM entry out of ifdef.

207774b213 armv8/ls2085a: Fix generic timer clock source
The timer clock is system clock divided by 4, not fixed 12MHz.
This is common to the SoC, not board specific. Primary core is
fixed when u-boot still runs in board_f. Secondary cores are
fixed by reading a variable set by u-boot.

f3f8c564a1 armv8/ls2085a: Update common header file
ls2085a_common.h contains hard-coded information for NOR/NAND flash,
I2C, DDR, etc. These are platform specific. Move them out of common
header file and placed into respective board header files.

Move TEXTBASE to 1MB offset to fit NOR flash with up to 1MB sector
size.

Enable command auto complete. Update prompt symbol. Set fdt_high to
0xa0000000 because Linux requires that the fdt  be 8-byte aligned
and below 512 MiB. Besides ensuring compliance with the 512 MiB
limit, this avoids problems with the dtb being misaligned within
the FIT image.

Change the MC FW, MC DPL and Debug server NOR addresses in compliance
with the NOR flash layouts for 128MB flash.

Add PCIe macros. Enable "loadb" command. Disable debug server.
Enable workaround for erratum A008511.
Stop reset on panic for postmortem debugging.

DDR3 has a special Precharge power-down mode: fast-exit vs slow-exit.

In slow-exit mode the DLL is off but in some quiescent state that makes it easy

In fast-exist mode the DLL is maintained such that it is ready again in about

32f9ef3e2b ARM: mxs: Get boot mode from OCRAM
Reading the boot mode pins after power-up does not necessarily represent the
boot mode used by the ROM loader. For example the state of a pin may have
changed because a recovery switch which was pressed to enter USB mode is
already released after plugging in USB.

The ROM loader stores the value a fixed address in OCRAM. Use this value
instead of reading the boot map pins.

The GLOBAL_BOOT_MODE_ADDR for i.MX28 is taken from an U-Boot patch for the
MX28EVK:
http://repository.timesys.com/buildsources/u/u-boot/u-boot-2009.08/u-boot-2009.08-mx28-201012211513.patch

Leave the boot mode detection for the i.MX23 untouched. Someone has to test
whether the i.MX ROM loader does also store the boot mode in OCRAM and if the
address match.

This patch superseeds my incorrect patch:
ARM: mxs: get boot mode from OTP

98cb0efde8 Add bootscript support to esbc_validate.
1. Default environment will be used for secure boot flow
 which can't be edited or saved.
2. Command for secure boot is predefined in the default
 environment which will run on autoboot (and autoboot is
 the only option allowed in case of secure boot) and it
 looks like this:
 #define CONFIG_SECBOOT \
 "setenv bs_hdraddr 0xe8e00000;"                 \
 "esbc_validate $bs_hdraddr;"                    \
 "source $img_addr;"                             \
 "esbc_halt;"
 #endif
3. Boot Script can contain esbc_validate commands and bootm command.
 Uboot source command used in default secure boot command will
 run the bootscript.
4. Command esbc_halt added to ensure either bootm executes
 after validation of images or core should just spin.

4e819950a5 ARM: UniPhier: use "select" instead of default value in defconfig
All the UniPhier boards have switch to Driver Model.
"select DM" is better than default value in each defconfig.

58d423b88e dm: select CONFIG_DM* options
As mentioned in the previous commit, adding default values in each
Kconfig causes problems because it does not co-exist with the
"depends on" syntax.  (Please note this is not a bug of Kconfig.)
We should not do so unless we have a special reason.  Actually,
for CONFIG_DM*, we have no good reason to do so.

Generally, CONFIG_DM is not a user-configurable option.  Once we
convert a driver into Driver Model, the board only works with Driver
Model, i.e. CONFIG_DM must be always enabled for that board.
So, using "select DM" is more suitable rather than allowing users to
modify it.  Another good thing is, Kconfig warns unmet dependencies
for "select" syntax, so we easily notice bugs.

Actually, CONFIG_DM and other related options have been added
without consistency: some into arch/*/Kconfig, some into
board/*/Kconfig, and some into configs/*_defconfig.

This commit prefers "select" and cleans up the following issues.

[1] Never use "CONFIG_DM=n" in defconfig files

It is really rare to add "CONFIG_FOO=n" to disable CONFIG options.
It is more common to use "# CONFIG_FOO is not set".  But here, we
do not even have to do it.
Less than half of OMAP3 boards have been converted to Driver Model.
Adding the default values to arch/arm/cpu/armv7/omap3/Kconfig is
weird.  Instead, add "select DM" only to appropriate boards, which
eventually eliminates "CONFIG_DM=n", etc.

[2] Delete redundant CONFIGs

Sandbox sets CONFIG_DM in arch/sandbox/Kconfig and defines it again
in configs/sandbox_defconfig.
Likewise, OMAP3 sets CONFIG_DM arch/arm/cpu/armv7/omap3/Kconfig and
defines it also in omap3_beagle_defconfig and devkit8000_defconfig.

a0e2b1b865 sunxi: usbc: Wait for vbus to fall after disabling it
When u-boot boots the board may be powering vbus, we turn off vbus in
sunxi_usbc_request_resources, if we are too quick with reading vusb-detect
after this we may see a residual charge and assume we've an external vusb
connected even though we do not. So when we see an external vusb wait a bit
and try again.

Without this when dealing with a pmic controller vbus and doing "reset" on
the u-boot console the musb host will only init once every other boot, because
the other boot it thinks an external vbus is present, this commit fixes this.

In addition, this allows more flexibility in vbus detection, as it could easily

79340db7f1 ARM: bcm2835: implement phys_to_bus/bus_to_phys
The BCM283[56] contain both a L1 and L2 cache between the GPU (a/k/a
VideoCore CPU?) and DRAM. DMA-capable peripherals can also optionally
access DRAM via this same  L2 cache (although they always bypass the L1
cache). Peripherals select whether to use or bypass the cache via the
top two bits of the bus address.

An IOMMU exists between the ARM CPU and the rest of the system. This
controls whether the ARM CPU's accesses use or bypass the L1 and/or L2
cache. This IOMMU is configured/controlled exclusively by the VideoCore
CPU.

In order for DRAM accesses made by the ARM core to be coherent with
accesses made by other DMA peripherals, we must program a bus address
into those peripherals that causes the peripheral's accesses to use the
same set of caches that the ARM core's accesses will use.

On the RPi1, the VideoCore firmware sets up the IOMMU to enable use of
the L2 cache. This corresponds to addresses based at 0x40000000.

On the RPi2, the VideoCore firmware sets up the IOMMU to disable use of
the L2 cache. This corresponds to addresses based at 0xc0000000.

This patch implements U-Boot's phys_to_bus/bus_to_phys APIs according
to those rules.

For full details of this setup, please see Dom Cobley's description at:

configuration where Kconfig set CONFIG_CPU_V7/CONFIG_CPU_ARM720T for
Tegra U-Boot Main/SPL, respectively.  But, until it was merged into

e049b772ae am33xx/ddr.c: Fix regression on DDR2 platforms
Back in fc46bae a "clean up" was introduced that intended to reconcile
some of the AM335x codepaths based on how AM43xx operates.
Unfortunately this introduced a regression on the DDR2 platforms.  This
was un-noticed on DDR3 (everything except for Beaglebone White) as we
had already populated sdram_config correctly in sequence.  This change
brings us back to the older behavior and is fine on all platforms.

Tested on Beaglebone White, Beaglebone Black and AM335x GP EVM

6102560891 Exynos5: Fix rpll_sdiv to support both peach-pit and peach-pi panels
The existing setting for rpll_sdiv generates 70.5Mhz RPLL
video clock to drive 1366x768 panel on peach_pit.

This clock rate is not sufficient to drive 1920x1080 panel on peach-pi.
So, we adjust rpll_sdiv to 3 so that it generates 141Mhz pixel clock
which can drive peach-pi LCD.

This change doesn't break peach-pit LCD since 141/2=70.5Mhz, i.e FIMD
divider at IP level will get set to 1(the required divider setting
will be calculated and set by exynos_fimd_set_clock()) and hence
peach-pit LCD still works fine.

79d75d7527 ARM: move -march=* and -mtune= options to arch/arm/Makefile
My main motivations for this commit are:

[1] Follow the arch/arm/Makefile style of Linux Kernel

[2] Maintain compiler options systematically
  Currently, we give -march=* and -mtune=* options inconsistently:
  Only some of the CPUs pass -march=* and -mtune=* options.
  By collecting such options into the single place arch/arm/Makefile
  we can tell which options are missing at a glance.

[3] Prepare for deprecating arch/*/cpu/*/config.mk

Note:
  This commit just moves the compiler options so as not to change
  the behavior at all.  It does not care about the correctness of
  the given options.  Fox example, "-march=armv5te" might be better
  than "-march=armv4" for ARM946EJS, but it is beyond the scope this
  commit.  Also, filling the missing -march=* and -tune=* is left
  to follow-up patches.

CONFIG_SYS_DCACHE_OFF conditional.  The same conditional in the
caller (arch/arm/mach-uniphier/cache_uniphier.c) is redundant.

a509161a21 ARM: UniPhier: disable L2 cache by lowlevel_init of U-Boot proper
The L2 cache is used as a temporary SRAM on SPL.
Now the secondary CPUs store the necessary code for jumping to
Linux on their L1 I-caches.  So, the L2 cache can be disabled
much earlier, at the very entry of U-Boot proper (lowlevel_init).
This makes the boot sequence clearer.
Also, as the L1 cache has been disabled by the start.S,
enable_caches() does not need to do it again.

62118b7b01 ARM: UniPhier: optimize kicking secondary CPUs code
Currently, the secondary CPU(s) are kicked three times:
Boot ROM ---(kick)--> SPL ---(kick)--> U-boot ---(kick)--> Linux.
It makes the boot sequence very complicated.

This commit merges the first and the second kicks, so the secondary
CPU(s) can directly jump from SPL to Linux.
arch/arm/mach-uniphier/smp.S is no longer necessary.

Linux boot test passed.

23b5877c64 armv8/vexpress64: make multientry conditional
While the Freescale ARMv8 board LS2085A will enter U-Boot both
on a master and a secondary (slave) CPU, this is not the common
behaviour on ARMv8 platforms. The norm is that U-Boot is entered
from the master CPU only, while the other CPUs are kept in
WFI (wait for interrupt) state.

The code determining which CPU we are running on is using the
MPIDR register, but the definition of that register varies with
platform to some extent, and handling multi-cluster platforms
(such as the Juno) will become cumbersome. It is better to only
enable the multiple entry code on machines that actually need
it and disable it by default.

Make the single entry default and add a special
ARMV8_MULTIENTRY KConfig option to be used by the
platforms that need multientry and set it for the LS2085A.
Delete all use of the CPU_RELEASE_ADDR from the Vexpress64
boards as it is just totally unused and misleading, and
make it conditional in the generic start.S code.

This makes the Juno platform start U-Boot properly.

dd09f7e73c ARM: PSCI: Rework the DT handler slightly
The way the PSCI DT update happens currently means we pull in
<asm/armv7.h> everywhere, including on ARMv8 and that in turn brings in
<asm/io.h> for some non-PSCI related things that header needs to deal
with.

To fix this, we rework the hook slightly.  A good portion of
arch/arm/cpu/armv7/virt-dt.c is common looking and I hope that when PSCI
is needed on ARMv8 we can re-use this by and large.  So rename the
current hook to psci_update_dt(), move the prototype to <asm/psci.h> and
add an #ifdef that will make re-use later easier.

114c86d826 arm: relocation: clear .bss section with arch memset if defined
For ARM architecture, enable the CONFIG_USE_ARCH_MEMSET/MEMCPY,
will highly increase the memset/memcpy performance. This is able
thanks to the ARM multiple register instructions.

Unfortunatelly the relocation is done without the cache enabled,
so it takes some time, but zeroing the BSS memory takes much more
longer, especially for the configs with big static buffers.

A quick test confirms, that the boot time improvement after using
the arch memcpy for relocation has no significant meaning.
The same test confirms that enable the memset for zeroing BSS,
reduces the boot time.

So this patch enables the arch memset for zeroing the BSS after
the relocation process. For ARM boards, this can be enabled
in board configs by defining: 'CONFIG_USE_ARCH_MEMSET'.

This was tested on Trats2.
A quick test with trace. Boot time from start to main_loop() entry:
- ~1384ms - before this change
-  ~888ms - after this change

7ae8350f67 ti: armv7: Move SPL SDRAM init to the right place, drop unused CONFIG_SPL_STACK
Currently in some cases SDRAM init requires global_data to be available
and soon this will not be available prior to board_init_f().  Adjust the
code paths in these cases to be correct.  In some cases we had the SPL
stack be in DDR as we might have large stacks (due to Falcon Mode +
Environment).  In these cases switch to CONFIG_SPL_STACK_R.  In other
cases we had simply been setting CONFIG_SPL_STACK into SRAM.  In these
cases we no longer need to (CONFIG_SYS_INIT_SP_ADDR is used and is also
in SRAM) so drop those lines.

db910353a1 arm: spl: Allow board_init_r() to run with a larger stack
At present SPL uses a single stack, either CONFIG_SPL_STACK or
CONFIG_SYS_INIT_SP_ADDR. Since some SPL features (such as MMC and
environment) require a lot of stack, some boards set CONFIG_SPL_STACK to
point into SDRAM. They then set up SDRAM very early, before board_init_f(),
so that the larger stack can be used.

This is an abuse of lowlevel_init(). That function should only be used for
essential start-up code which cannot be delayed. An example of a valid use is
when only part of the SPL code is visible/executable, and the SoC must be set
up so that board_init_f() can be reached. It should not be used for SDRAM
init, console init, etc.

Add a CONFIG_SPL_STACK_R option, which allows the stack to be moved to a new
address before board_init_r() is called in SPL.

The expected SPL flow (for CONFIG_SPL_FRAMEWORK) is documented in the README.

bdfb34167f dm: tegra: Enable driver model in SPL and adjust the GPIO driver
Use the full driver model GPIO and serial drivers in SPL now that these are
supported. Since device tree is not available they will use platform data.

Remove the special SPL GPIO function as it is no longer needed.

This is all in one commit to maintain bisectability.

fc8fdc76e7 arm: spl: Avoid setting up a duplicate global data structure
This is already set up in crt0.S. We don't need a new structure and don't
really want one in the 'data' section of the image, since it will be empty
and crt0.S's changes will be ignored.

As an interim measure, remove it only if CONFIG_DM is not defined. This
allows us to press ahead with driver model in SPL and allow the stragglers
to catch up.

24a6bc010e arm: Reduce the scope of lowlevel_init()
This function has grown into something of a monster. Some boards are setting
up a console and DRAM here in SPL. This requires global_data which should be
set up in one place (crt0.S).

There is no need for SPL to use s_init() for anything since board_init_f()
is called immediately afterwards.

This fixes the MMC/SD card detect GPIOs for Apalis T30 which got broken
by the following commit:

2b2b50bc87 "dm: tegra: dts: Use TEGRA_GPIO() macro for all GPIOs"

While at it also re-add the comments describing which particular
Apalis/Colibri pins those GPIOs are on.
