5c76f78858 ARM: keystone2: add K2E SoC hardware definitions
This patch adds hardware definitions specific to Keystone II
K2E device. It has a lot common definitions with k2hk SoC, so
move them to common hardware.h. This is preparation patch for
adding K2E SoC support.

8dfc15f56c ARM: keystone: clock: move K2HK SoC dependent code in separate file
This patch in general spit SoC type clock dependent code and general
clock code. Before adding keystone II Edison k2e SoC which has
slightly different dpll set, move k2hk dependent clock code to
separate clock-k2hk.c file.

3d31538625 k2hk: use common KS2_ prefix for all hardware definitions
Use KS2_ prefix in all definitions, for that replace K2HK_ prefix and
add KS2_ prefix where it's needed. It requires to change names also
in places where they're used. Align lines and remove redundant
definitions in kardware-k2hk.h at the same time.

Using common KS2_ prefix helps resolve redundant redefinitions and
adds opportunity to use KS2_ definition across a project not thinking about
what SoC should be used. It's more convenient and we don't need to worry
about the SoC type in common files, hardware.h will think about that.
The hardware.h decides definitions of what SoC to use.

This driver is needed in case if keystone driver is used.
Currently only keystone_net driver uses it. So to avoid

fb2fcb798a ARM: omap: Fix GPMC init for OMAP3 platforms
Commit a0a37183 (ARM: omap: merge GPMC initialization code for all
platform) broke NAND on OMAP3 based platforms. I noticed this while
testing the latest 2014.07-rc version on the TAO3530 board. NAND
detection did not work with this error message:

NAND:  nand: error: Unable to find NAND settings in GPMC Configuration - quitting

As OMAP3 configs don't set CONFIG_NAND but CONFIG_NAND_CMD. the GPMC
was not initialized for NAND at all. This patch now fixes this issue.

Tested on TAO3530 board.

c4f80f5003 am335x_evm / gumstix pepper: Correct DDR settings
As noted by clang, we have been shifting certain values out of 32bit
range when setting some DDR registers.  Upon further inspection these
had been touching reserved fields (and having no impact).  These came in
from historical bring-up code and can be discarded.  Similarly, we had
been declaring some fields as 0 when they will be initialized that way.
Tested on Beaglebone White.

0a11d6f29c mx6: Remove duplication of iomuxc structure
There is no need to keep iomuxc_base_regs structure as it serves the exact same
purpose of the iomuxc structure, which is to provide access to the GPR
registers.

The additional fields of iomuxc_base_regs are not used. Other advantage of
'iomuxc' is that it has a shorter name and the variable declarations can fit
into a single line.

So remove iomuxc_base_regs structure and use iomuxc instead.

b940ca64b2 armv8/fsl-lsch3: Add support to load and start MC Firmware
Adding support to load and start the Layerscape Management Complex (MC)
firmware. First, the MC GCR register is set to 0 to reset all cores. MC
firmware and DPL images are copied from their location in NOR flash to
DDR. MC registers are updated with the location of these images.
Deasserting the reset bit of MC GCR register releases core 0 to run.
Core 1 will be released by MC firmware. Stop bits are not touched for
this step. U-boot waits for MC until it boots up. In case of a failure,
device tree is updated accordingly. The MC firmware image uses FIT format.

261d27605c arm: Add support for semihosting for armv8 fastmodel targets.
The armv8 ARM Trusted Firmware (ATF) can be used to load various ATF
images and u-boot, and does this for virtual platforms by using
semihosting. This commit extends this idea by allowing u-boot to also
use semihosting to load the kernel/ramdisk/dtb. This eliminates the need
for a bootwrapper and produces a more realistic boot sequence with
virtual models.

Though the semihosting code is quite generic, support for armv7 in
fastmodel is less useful due to the wide range of available silicon
and the lack of a free armv7 fastmodel, so this change contains an
untested armv7 placeholder for the service trap opcode.

Please refer to doc/README.semihosting for a more detailed description
of semihosting and how it is used with the armv8 virtual platforms.

68049a082b i2c: tegra: use repeated start for reads
I2C read transactions are typically implemented as follows:

START(write) address REPEATED_START(read) data... STOP

However, Tegra's I2C driver currently implements reads as follows:

START(write) address STOP START(read) data... STOP

This sequence confuses at least the AS3722 PMIC on the Jetson TK1 board,
leading to corrupted read data in some cases. Fix the driver to chain
the transactions together using repeated starts to solve this.

8e4ab1d582 Exynos5420: Introduce support for the Peach-Pit board
While the Exynos5420 chip is used in both Smdk5420 and in the Peach-Pit
line of devices, there could be other boards using the same chip, so a
common configuration file is being added (exynos5420.h) as well
as two common device tree files (exynos54xx.dtsi & exynos5420.dtsi).

The peach board as declared in boards.cfg is a copy of smdk5420
declaration. The configuration files are similar, but define different
default device trees, console serial ports and prompts.

The device tree files for smdk5420 and peach-pit inherit from the same
common file.

gpmc timeout is disabled and the reset counter
is set to 0. However, if later a driver activates
the timeout setting the reset to a valid value,
the old reset value with zero is still valid
for the first access. In fact, the timeout block
loads the reset counter after a successful access.

Found on a am335x board with a FPGA connected
to the GPMC bus together with the NAND.
When the FPGA driver in kernel activates
the timeout, the system hangs at the first access
by the NAND driver.

Also, disabling h/w read leveling improves the MIF LVcc value

afee59cd49 keystone: init: enable UART1 to be able use it from kernel
Currently PWREMU_MGMT is not configured in the Linux generic UART
driver as this register seems to be specific TI UART IP. So this
needs to be enabled in u-boot to use UART1 from kernel space.

196311dc72 arm:am33xx: Rework s_init and add board_early_init_f
With the changes to the i2c framework (and adopting the omap24xx_i2c
driver to them) we can no longer call i2c functions prior to gd having
been set and cleared.  When SPL booting, this is handled by setting gd
to point to SRAM in s_init.  However in the cases where we are loaded
directly by ROM (memory mapped NOR or QSPI) we need to make use of the
normal hooks to slightly delay these calls.

87acf194a2 arm:am33xx: Make dram_init call sdram_init() in some contexts
We have two contexts for booting these platforms.  One is SPL which is
roughly: reset, cpu_init_crit, lowlevel_init, s_init, sdram_init, _main,
board_init_f from SPL, ... then U-Boot loads.  The other is a
memory-mapped XIP case (NOR or QSPI) where we do not run an SPL.  In
this case we go, roughly: reset, cpu_init_crit, lowlevel_init, s_init,
_main, regular board_init_f.

In the first case s_init will set a valid gd and then be able to call
sdram_init which in many cases will need i2c (which needs a valid gd for
gd->cur_i2c_bus).  In this second case we must (and are able to and
should) defer sdram_init() into dram_init() called by board_init_f as gd
will have been set in _main and cleared in board_init_f.

The ePOS EVM and EVM SK have QSPI as an option to boot.  Add a qspiboot
target that utilizes QSPI for env and so forth as an example of best
practices.  As QSPI is booted from directly we need to chang
CONFIG_SYS_TEXT_BASE.

Note that on ePOS EVM the QSPI and NAND are mutually exclusive choices
we need to handle that elsewhere, once NAND support is also added.

Add memory-mapped structures for MMDC iomux and configuration. Note that whi
the MMDC configuration registers are common between the IMX6DQ
(IMX6DUAL/IMX6QUAD) and IMX6SDL (IMX6SOLO/IMX6DUALLITE) types the iomux
registers differ. This requires two sets of structures.

Add structures to describe DDR3 device information, system information
(memory layout, etc), and MMDC calibration registers that can be used to
configure the MMDC dynamically.

We define these structures for SPL builds instead of including mx6q-ddr.h an
mx6dl-ddr.h which use the same namespace and are only useful for imximage cf
files.

9f2ec3f543 spl: consolidate arch/arm/include/asm/arch-*/spl.h
arch/arm/include/asm/spl.h requires all SoCs to have
arch/arm/include/asm/arch-*/spl.h.

But many of them just define BOOT_DEVICE_* macros.

Those macros are used in the "switch (boot_device) { ... }"
statement in common/spl/spl.c.

So they should not be archtecture specific, but be described as
a simpile enumeration.

This commit merges most of arch/arm/include/asm/arch-*/spl.h
into arch/arm/include/asm/spl.h.

With a little more effort, arch-zynq/spl.h and arch-socfpga/spl.h
will be merged, while I am not sure about OMAP and Exynos.

It's "correct" in so far as it works (the boards.cfg config stuff
#defines things to 1), but I think you are right that it isn't the
preferred style. But...

...I had thought that it was to support some other board which wasn't
being upstreamed right now, so eventually useful and harmless for now,
but I've just checked and it isn't actually used by any of the boards in
u-boot-sunxi.git. So rather than fix it to use #ifdef lets drop it.
Rather than resend the entire series, here is v5.1 of this patch.

a0a37183bd ARM: omap: merge GPMC initialization code for all platform
GPMC controller on TI's OMAP SoC is general purpose controller to interface
with different types of external devices like;
 - parallel NOR flash
 - parallel NAND flash
 - OneNand flash
 - SDR RAM
 - Ethernet Devices like LAN9220

Though GPMC configurations may be different for each platform depending on
clock-frequency and external device interfacing with controller. But
initialization sequence remains common across all platfoms.

Thus this patch merges gpmc_init() scattered in different arch-xx/mem.c
files into single omap-common/mem-common.c

However, actual platforms specific register config values are still sourced
from corresponding platform specific headers like;
 AM33xx: arch/arm/include/asm/arch-am33xx/mem.h
 OMAP3:  arch/arm/include/asm/arch-omap3/mem.h
 OMAP4:  arch/arm/include/asm/arch-omap4/mem.h
 OMAP4:  arch/arm/include/asm/arch-omap5/mem.h

Also, CONFIG_xx passed by board-profile decide config for which set of macros
need to be used for initialization
 CONFIG_NAND:    initialize GPMC for NAND device
 CONFIG_NOR:     initialize GPMC for NOR device
 CONFIG_ONENAND: initialize GPMC for ONENAND device

a4539a2aa7 usb: tegra: support device mode
A few changes are made to the Tegra EHCI driver so that it can set
everything up for device-mode operation on the first USB controller.
This can be used in conjunction with ci_udc.c to operate as a USB
device.

Detailed changes are:

* Rename set_host_mode() to set_up_vbus() since that's really what it
  does.

* Modify set_up_vbus() to know whether it's initializing in host or
  device mode, and:

  - Skip the external VBUS check in device mode, since external VBUS is
    expected in this case.

  - Disable VBUS output in device mode.

* Modify init_phy_mux() to know whether it's initializing in host or
  device mode, and hence skip setting USBMODE_CM_HC (which enables host
  mode) in device mode. See the comments in that function for why this
  is safe w.r.t. the ordering requirements of PHY selection.

* Modify init_utmi_usb_controller() to force "b session valid" in device
  mode, since the HW requires this. This is done in UTMI-specific code,
  since we only support device mode on the first USB controller, and that
  controller can only talk to a UTMI PHY.

* Enhance ehci_hcd_init() to error-check the requested host-/device-mode
  vs. the dr_mode (dual-role mode) value present in device tree, and the
  HW configurations which support device mode.

* Enhance ehci_hcd_init() not to skip HW initialization when switching
  between host and device mode on a controller. This requires remembering
  which mode the last initialization used.

ps7_init.c and ps7_init.h are supposed to be exported by hw project
and copied to board/xilinx/zynq/ directory.

We want them to be ignored by git.
So what we should do is to always treat them as external files
rather than replacing ps7_init.c

This commit does:

 - Move a weak function ps7_init() to arch/arm/cpu/armv7/zynq/spl.c
   and delete board/xilinx/zynq/ps7_init.c

 - Compile board/xilinx/zynq/ps7_init.c only when it exists

2364e151e4 ARM: tegra: use a CPU freq that all SKUs can support
U-Boot on Tegra30 currently selects a main CPU frequency that cannot be
supported at all on some SKUs, and needs higher VDD_CPU/VDD_CORE values
on some others. This can result in unreliable operation of the main CPUs.

Resolve this by switching to a CPU frequency that can be supported by any
SKU. According to the following link, the maximum supported CPU frequency
of the slowest Tegra30 SKU is 600MHz:

repo http://nv-tegra.nvidia.com/gitweb/?p=linux-2.6.git;a=summary
branch l4t/l4t-r16-r2
path arch/arm/mach-tegra/tegra3_dvfs.c
table cpu_dvfs_table[]

According to that same table, the minimum VDD_CPU required to operate at
that frequency across all SKUs is 1.007V. Given the adjustment resolution
of the TPS65911 PMIC that's used on all Tegra30-based boards we support,
we'll end up using 1.0125V instead.

At that VDD_CPU, tegra3_get_core_floor_mv() in that same file dictates
that VDD_CORE must be at least 1.2V on all SKUs. According to
tegra_core_speedo_mv() (in tegra3_speedo.c in the same source tree),
that voltage is safe for all SKUs.

An alternative would be to port much of the code from tegra3_dvfs.c and
tegra3_speedo.c in the kernel tree mentioned above. That's more work
than I want to take on right now.

While all the currently supported boards use the same regulator chip for
VDD_CPU, different types of regulators are used for VDD_CORE. Hence, we
add some small conditional code to select how VDD_CORE is programmed. If
this becomes more complex in the future as new boards are added, or we
end up adding code to detect the SoC SKU and dynamically determine the
allowed frequency and required voltages, we should probably make this a
runtime call into a function provided by the board file and/or relevant
PMIC driver.

eceb3f26f4 ARM: tegra: add GPIO initialization table function
The HW-defined procedure for booting Tegra requires that some pins be
set up as GPIOs immediately at boot in order to avoid glitches on those
pins, when the pinmux is programmed. Add a feature to the GPIO driver
which executes a GPIO configuration table. Board files will use this to
implement the correct HW initialization procedure.
