[U-Boot] [PATCH 0/8] dm: rockchip: Enable booting from MMC

[Sjoerd Simons]

This patchset allows u-boot on RK3288 device to load and boot kernels
from MMC using the standard distro boot commands. Patchset is on top of
the rockchip-working branch of u-boot dm

There are some small oddities with the support:
- Linux crashes when try to use the FDT if it's re-allocated to memory
  locations above 512MB. So fdt_high is set to ensure it stays below
  that.
- This SoC seems sensitive to the order in which the caches are
  disabled, when disabling the i-cache before the d-cache starting linux
  fails (unsure if it fails before or after jumping to linux though)

To fix the latter ``arm: Turn of d-cache before i-cache'' changes the
ordering in the general v7 code. However i have not tested this yet on
other device, so it may well need to be handled in rockchip specific
code.

Tested on a Radxa Rock 2 with square baseboard, booting from SD card. I
haven't tested eMMC yet however i suspect the SPL will need
modifications there to load u-boot from eMMC rather then SD (which has
index 0) ideally by detecting where the SPL itself got loaded from.
