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.

Freescale LayerScape with Chassis Generation 3 is a set of SoCs with
ARMv8 cores and 3rd generation of Chassis. We use different MMU setup
to support memory map and cache attribute for these SoCs. MMU and cache
are enabled very early to bootst performance, especially for early
development on emulators. After u-boot relocates to DDR, a new MMU
table with QBMan cache access is created in DDR. SMMU pagesize is set
in SMMU_sACR register. Both DDR3 and DDR4 are supported.

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.

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.

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,

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.

SerDes PLL is calibrated at reset. When the junction temperature
delta from the time the PLL is calibrated exceeds +56C/-66C,
jitter may increase and can cause PLL to unlock.
This workaround overwrite the SerDes registers with new values,
to calibrate SerDes registers.
These values are known to work fine for all temperature ranges.
This workaround is valid for B4, T4 and T2 platforms, so
added in their config.

When the DDR controller is initialized below a junction temperature of

A-007186: SerDes PLL is calibrated at reset. It is possible for jitter to
increase and cause the PLL to unlock when the temperature delta from the
time the PLL is calibrated exceeds +56C/-66C when using X VDD of 1.35 V
(or +70C/-80C when using XnVDD of 1.5 V). No issues are seen with LC
VCO. Only the protocols using Ring VCOs are impacted.
Workaround:
For all 1.25/2.5/5 GHz protocols, use LC VCO instead of Ring VCO, this need
to use alternate serdes protocols. The alternate option has the same
functionality as the original option; the only difference being LC VCO
rather than Ring VCO.

The relocation code can now relocate from anywhere to
the RAM.
The old code assumed that the binary was copied to the RAM
by some PBL and then it just relocated the .text section
from the loaded address to the linked address.
Now, it first checks if vectors are somewhere else than the
linked address. If yes, there are copied to address 0 (or
to the exception vector base address if register EVBAR is
present).
Then, the .text section is relocated from its current location
to the RAM.

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

...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.

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
