2014-07-25am335x_evm / gumstix pepper: Correct DDR settingsTom Rini
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.

The pad settings for DISP0_DATA02 and DISP0_DAT10 were not set in the same way as DISP0_DAT00-23, causing much flicker in parallel RGB displays on Dual-Lite and Solo processors.

2014-07-03armv8/fsl-lsch3: Add support to load and start MC FirmwareJ. German Rivera
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. Signed-off-by: J.

2014-07-03arm: Add support for semihosting for armv8 fastmodel targets.Darwin Rambo
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.

2014-07-03i2c: tegra: use repeated start for readsStephen Warren
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. Signed-off-by: Stephen Warren <swarren@nvidia.com> Reviewed-by: Yen Lin <yelin@nvidia.com>

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.
