2017-09-14ARM: at91: spl: Add mck function to lower rate while switchingWenyou Yang
Refer to the commit 70f8c8316ad(PMC: add new mck function to lower rate while switching) from AT91Bootstrap. While switching to a lower clock source, we must switch the clock source first instead of last. Otherwise, we could end up with too high frequency on internal bus and peripherals. This happens on SAMA5D2 as exitting from the ROM code. Add a function pmc_mck_init_down() to allow this sequence.

2017-09-14clk: at91: utmi: Set the reference clock frequencyWenyou Yang
By default, it is assumed that the UTMI clock is generated from a 12 MHz reference clock (MAINCK). If it's not the case, the FREQ field of the SFR_UTMICKTRIM has to be updated to generate the UTMI clock in the proper way. The UTMI clock has a fixed rate of 480 MHz. In fact, there is no multiplier we can configure. The multiplier is managed internally, depending on the reference clock frequency, to achieve the target of 480 MHz.

2017-08-13spl: add hierarchical defaults for SPL_LDSCRIPTPhilipp Tomsich
With SPL_LDSCRIPT moved to Kconfig (and this being a 'string' config node), all the lingering definitions in header files will cause warnings/errors due to the redefinition of the configuration item. As we don't want to pollute the defconfig files (and values should usually be identical for entire architectures), the defaults are moved into Kconfig. Kconfig will always pick the first default that matches, so please keep these values at the end of each file (to allow any board-specific Kconfig, which will be included earlier) to override with an unconditional default setting.

2016-06-26common: Pass the boot device into spl_boot_mode()Marek Vasut
The SPL code already knows which boot device it calls the spl_boot_mode() on, so pass that information into the function. This allows the code of spl_boot_mode() avoid invoking spl_boot_device() again, but it also lets board_boot_order() correctly alter the behavior of the boot process. The later one is important, since in certain cases, it is desired that spl_boot_device() return value be overriden using board_boot_order().

2016-05-24ARM: sama5d2: Implement boot device autodetectionMarek Vasut
Implement support for saving ARM register R4 early during boot using save_boot_params . Implement support for decoding the stored register R4 value in spl_boot_device() to obtain boot device from which the SoC booted. This way, the SPL will always load U-Boot from the same device from which the SPL itself booted instead of using hard-coded boot device. This functionality is useful for example when booting sama5d2-xplained from SD card, where by default the SPL would try loading the U-Boot from eMMC and fail. This is because eMMC is on SDHCI0 (BOOT_DEVICE_MMC1), while SD slot is on SDHCI1 (BOOT_DEVICE_MMC2) and the SPL was hard-wired to always boot from BOOT_DEVICE_MMC1.
