e2748b4167 imx: mx6: correct enable_fec_anatop_clock
We should follow 'read->set/clr bit->write' flow for enable_fec_anatop_clock,
otherwise we may overridden configuration before enable_fec_anatop_clock.

af654d1461 sunxi: retrieve FEL-provided values to environment variables
This patch extends the misc_init_r() function on sunxi boards
to test for the presence of a suitable "sunxi" SPL header. If
found, and the loader ("fel" utility) provided a non-zero value
for the boot.scr address, then the corresponding environment
variable fel_scriptaddr gets set.

misc_init_r() also sets (or clears) the "fel_booted" variable depending
on the active boot device, using the same logic as spl_boot_device().

The goal is to provide sufficient information (within the U-Boot
environment) to make intelligent decisions on how to continue the boot
process, allowing specific customizations for the "FEL boot" case.

68282f55b8 arm: Remove unused ST-Ericsson u8500 arch
This arch does not seem to be supported / used at all in the current
U-Boot mainline source tree any more. So lets remove the core u8500 code
and code that was only referenced by this platform.

Please note that this patch also removes these config options:

- CONFIG_PL011_SERIAL_RLCR
- CONFIG_PL011_SERIAL_FLUSH_ON_INIT

As they only seem to be referenced by u8500 based boards. Without any
such board in the current code, these config option don't make sense
any more. Lets remove them as well.

If someone still wants to use this platform, then please send patches
to re-enable support by adding at least one board that references this
code.

d9cbb264e8 imx: mx6ul: support mx6ul 9x9 evk board
This patch is to support mx6ul_9x9_evk board based on mx6ul_14x14_evk,
the difference between mx6ul 9x9 evk and mx6ul 14x14 evk are:
1. mx6ul 9x9 evk use pfuze3000, while mx6ul 14x14 evk use DCDC.
2. mx6ul 9x9 evk supports 256MB LPDDR2, while mx6ul 14x14 evk
   supports 512MB DDR3
3. mx6ul_9x9_evk use 9x9 package, while mx6ul_14x14_evk use 14x14 package.

This patch add the following:
1. Discard PHYS_SDRAM_SIZE from header file, use imx_ddr_size()
2. Introduce a macro is_mx6ul_9x9_evk using
   CONFIG_IS_ENABLED(TARGET_MX6UL_9X9_EVK) to avoid "#ifdef xxx" in non-SPL
   part. To SPL part, CONFIG_IS_ENABLED(TARGET_MX6UL_9X9_EVK) can not work,
   so still use "#ifdef CONFIG_TARGET_MX6UL_9X9_EVK" to differentiate with
   mx6ul_14x14_evk. And we have no way to dymaically checking this chip
   is 9x9 or 14x14.
3. mx6ul_9x9_evk use pfuze3000, so enabled POWER related configurations.
   POWER related configurations also effect for mx6ul_14x14_evk. But
   power_init_board implementation using 'if (is_mx6ul_9x9_evk())' to
   do initialization for mx6ul_9x9_evk, and do nothing for mx6ul_14x14_evk.
4. mx6ul_9x9_evk use lpddr2 with size 256MB, so add related SPL DRAM
   configurations.
5. Enable CONFIG_ENV_VARS_UBOOT_RUNTIME_CONFIG and setting dtb file
   according to board_rev and board_name.
6. Add TARGET_MX6UL_9X9_EVK Kconfig entry

208bd51396 arm: armv8 correct value passed to __asm_dcache_all
>From source code comments:
"x0: 0 flush & invalidate, 1 invalidate only"

Current value 0xffff can make invalidate work, since we only judge whether
input value is 0 or not, see following code:
"
    tbz     w1, #0, 1f
    dc      isw, x9
    b       2f
1:  dc      cisw, x9      /* clean & invalidate by set/way */
2:  subs    x6, x6, #1    /* decrement the way */
"

Later we may add "2 clean only" support. So following the comments,
correct value from 0xffff to 1.

This patch adds the "nandecc" command to switch between the SPEAr600 internal

chips with a stronger ECC than 1-bit, as on the x600. And to dynamically
switch between both ECC schemes for backwards compatibility.

81b0618ddf arm: Turn of d-cache before i-cache
Booting the kernel fails on RK3288 (and probably other rockchip SoCs)
when the i-cache is disabled/flushed before d-cache.

I have not investigated whether this is due to U-Boot hanging or whether
it's very early in the linux boot, but following the approach of the
various rockchip U-Boot forks (first disable d-cache then i-cache) makes
things work.

This patch fixes recent build issues introduced by the patch

8ceb34a1d1 omap-common: SYS_BOOT fallback logic correction and support for more devices
The SYS_BOOT-based fallback shouldn't only check for one of the conditions of
use and then let the switch/case handle each boot device without enforcing the
conditions for each type of boot device again.

For instance, this behaviour would trigger the fallback for UART when
BOOT_DEVICE_UART is defined, CONFIG_SPL_YMODEM_SUPPORT is enabled (which should
be a show-stopper) and e.g. BOOT_DEVICE_USB is enabled and not
CONFIG_SPL_USB_SUPPORT.
Separating the logic for USB and UART solves this.

In addition, this adds support for more peripheral devices (USBETH and CPGMAC)
to the fallback mechanism. Note that the USBETH boot device should always be
different from the USB boot device (each should match a different bootrom
handoff case).

76cff2b108 ARM: DRA74-evm: Use SMA_1 spare register to workaround DP83865 phy on SR2.0
DP83865 ethernet phy used on DRA74x-evm is quirky and the datasheet
provided IODELAY values for standard RGMII phys do not work.

Silicon Revision(SR) 2.0 provides an alternative bit configuration
that allows us to do a "gross adjustment" to launch the data off a
different internal clock edge. Manual IO Delay overrides are still
necessary to fine tune the clock-to-data delays. This is a necessary
workaround for the quirky ethernet Phy we have on the platform.

NOTE: SMA registers are spare "kitchen sink" registers that does
contain bits for other workaround as necessary as well. Hence the
control for the same is introduced in a generic SoC specific, board
generic location.

This patch moves pxa to the common timer functions added in commit

  8dfafdd - Introduce common timer functions <Rob Herring>

The (removed) pxa timer code (specifically __udelay()) could deadlock at
the 32-bit boundary of get_ticks().  get_ticks() returned a 32-bit value
cast up to a 64-bit value.  If get_ticks() + tmo in __udelay() crossed
the 32-bit boundary, the while condition became unconditionally true and
locked the processor.  Rather than patch the specific pxa issues, simply
move everything over to the common code.

- Include DT file now for the "AM335x GP EVM" and build target for it,
  via device tree and DM.
- We only need to provide platform data for UART when OF_CONTROL isn't
  also enabled really.  We can just push GPIO to coming from DT

e86c953059 imx28: Fix issue with GCC 5.x
The semantics for non-static functions declared inline have changed in
gcc5, causing the empty functions not to be emitted as an external
symbol.

Since lowlevel_init() is only referenced from start.S, it should not be
declared inline at all.

095a5ef88e ARM: DRA72: disable workaround for 801819
DRA72x processor variants are single core and it does not export ACP[1].
Hence, we have no source for generating an external snoop requests which
appear to be key to the deadlock in DRA72x design.

Since we build the same image for DRA74x and DRA72x platforms, lets
runtime detect and disable the workaround (in favor of performance) on
DRA72x platforms.

a615d0be6a ARM: Introduce erratum workaround for 801819
Add workaround for Cortex-A15 ARM erratum 801819 which says in summary
that "A livelock can occur in the L2 cache arbitration that might
prevent a snoop from completing. Under certain conditions this can
cause the system to deadlock. "

Recommended workaround is as follows:
Do both of the following:

1) Do not use the write-back no-allocate memory type.
2) Do not issue write-back cacheable stores at any time when the cache
is disabled (SCTLR.C=0) and the MMU is enabled (SCTLR.M=1). Because it
is implementation defined whether cacheable stores update the cache when
the cache is disabled it is not expected that any portable code will
execute cacheable stores when the cache is disabled.

For implementations of Cortex-A15 configured without the “L2 arbitration
register slice” option (typically one or two core systems), you must
also do the following:

3) Disable write-streaming in each CPU by setting ACTLR[28:25] = 0b1111

So, we provide an option to disable write streaming on OMAP5 and DRA7.
It is a rare condition to occur and may be enabled selectively based
on platform acceptance of risk.

Applies to: A15 revisions r2p0, r2p1, r2p2, r2p3 or r2p4 and REVIDR[3]
is set to 0.

Note: certain unicore SoCs *might* not have REVIDR[3] not set, but
might not meet the condition for the erratum to occur when they donot
have ACP (Accelerator Coherency Port) hooked to ACE (AXI Coherency
Extensions). Such SoCs will need the work around handled in the SoC
specific manner, since there is no ARM generic manner to detect such
configurations.

Based on ARM errata Document revision 18.0 (22 Nov 2013)

633b6ccedf ARM: cache: implement a default weak flush_cache() function
Current many cpu use the same flush_cache() function, which just call
the flush_dcache_range().
So implement a weak flush_cache() for all the cpus to use.

In original weak flush_cache() in arch/arm/lib/cache.c, there has some
code for ARM1136 & ARM926ejs. But in the arch/arm/cpu/arm1136/cpu.c and
arch/arm/cpu/arm926ejs/cache.c, there implements a real flush_cache()
function as well. That means the original code for ARM1136 & ARM926ejs
in weak flush_cache() of arch/arm/lib/cache.c is totally useless.

So in this patch remove such code in flush_cache() and only call
flush_dcache_range().

Since some driver like ohci, lcd used dcache functions. But some ARM
cpu don't implement the invalidate_dcache_range()/flush_dcache_range()
functions.

To avoid compiling errors this patch adds an weak empty stub function
for all ARM cpu in arch/arm/lib/cache.c.
And ARM cpu still can implemnt its own cache functions on the cpu folder.

0257930ba0 LG Optimus Black (P970) codename sniper support
The LG Optimus Black (P970) codename sniper is a smartphone that was designed
and manufactured by LG Electronics (LGE) and released back in 2011.

It is using an OMAP3630 SoC GP version, which allows running U-Boot and the
U-Boot SPL from the ground up. This port is aimed at running an Android version
such as Replicant, the fully free Android distribution. However, support for
upstream Linux with device-tree and common GNU/Linux distros boot commands
could be added in the future.
