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.

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.

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.

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.

734af242c2 OMAP: disable gpmc timeout safely for reenabling
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.

all go away, so we'll do that as per Samsung suggestion.

We also check the "is it locked" bits of PHY_CON13 and loop until they
show the the value sampled actually represents a locked value.  It
doesn't appear that the glitching and "is it locked" are related, but
it seems wise to wait until the PHY tells us the value is good before
we use it.  In practice we will not loop more than a couple times (and
usually won't loop at all).

aacdd79095 Exynos5420: Remove code for enabling read leveling
This patch intends to remove all code which enables hardware read
leveling. All characterization environments may not cope up with
h/w read leveling enabled, so we must disable this.
Also, disabling h/w read leveling improves the MIF LVcc value
(LVcc value is the value at which DDR will fail to work properly).
Improving LVcc means we have enough voltage margin for MIF.
When h/w leveling is enabled, we have almost zero volatge margin.

b924d586d7 arm64: zero cntvoff_el2
Currently cntvoff_el2 is initialised with an arbitrary bag of bits
derived from the initial value of cnthctl_el2 on the current CPU. This is
somewhat odd and problematic as some of these bits are UNKNOWN at reset
and may differ across CPUs (which may cause an OS at EL1 to observe time
going backwards across CPUs).

This patch instead initialises cntvoff_el2 with xzr, giving the register
a consistent value of zero on all CPUs.
