* [U-Boot] [PATCH v1] spl: eMMC/SD: Provide one __weak spl_boot_mode() function

  To: u-boot

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.

Comments regarding cleanup (to help maintainers assessment if those changes
break anything):

Implementations necessary to stay as is:
----------------------------------------
- SW fix for broken ROM boot code
        arch/arm/mach-uniphier/mmc-boot-mode.c

- Omap specific adjustments:
        arch/arm/mach-omap2/boot-common.c

Below archs had a bit off-standard approach, but were eligible for using
the __weak function:
--------------------
- at91 -> check if proper configs flags in the weak function are set:
        arch/arm/mach-at91/spl.c

- zyncmp -> the BOOT_DEVICE_RAM return of spl_boot_mode seems like an error
        (will hang in spl_mmc_load_image() anyway)
        arch/arm/cpu/armv8/zynqmp/spl.c

- fsl -> here we had a return of BOOT_DEVICE_NAND, but the spl_boot_mode is
        eMMC/SD card specific
        (will hang in spl_mmc_load_image() anyway)

        arch/arm/cpu/armv8/fsl-layerscape/spl.c
        arch/arm/cpu/armv7/ls102xa/spl.c
        arch/arm/cpu/arm1136/mx35/generic.c

Test HW:

iMX6Q - display5 board

You should run it through Travis at least, to detect if something
stopped building.
