d695d66278 spl: eMMC/SD: Provide one __weak spl_boot_mode() function
The goal of this patch is to clean up the code related to choosing SPL
MMC boot mode.

The spl_boot_mode() now is called only in spl_mmc_load_image() function,
which is only compiled in if CONFIG_SPL_MMC_SUPPORT is enabled.

To achieve the goal, all per mach/arch implementations eligible for
unification has been replaced with one __weak implementation.

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.

e7c831543a clk: at91: utmi: Set the reference clock frequency
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.

The patch is cloned from the patch of mailing-list:

b529993e02 spl: add hierarchical defaults for SPL_LDSCRIPT
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.

968ebdf1ef ARM: at91: Don't invoke spl_boot_device() twice
Since the spl_boot_mode() is now passed the boot device to boot from,
make use of it instead of inquiring for the boot device again. This
allows board_boot_order() to function correctly.

2b1cdafa9f common: Pass the boot device into spl_boot_mode()
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().

bb0c63a5f3 ARM: sama5d2: Implement boot device autodetection
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.
