2014-07-09mx6: soc: Update the comments of set_ldo_voltage()Fabio Estevam
Commit 3d622b78 (mx6: soc: Introduce set_ldo_voltage()) introduces set_ldo_voltage() function that can be used to set the voltages of any of the three LDO regulators controlled by the PMU_REG_CORE register. Prior to this commit there was a single set_vddsoc() which only configured the VDDSOC regulator. Update the comments to align with the new set_ldo_voltage() implementation.

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>

2014-06-23Exynos5420: Introduce support for the Peach-Pit boardAkshay Saraswat
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.

2014-06-19OMAP: disable gpmc timeout safely for reenablingStefano Babic
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. Signed-off-by: Stefano Babic <sbabic@denx.de>

when CLKM is running. If we stop CLKM when sampling it the glitches 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.
