1ac63e4094 powerpc/85xx: Enable eSDHC boot support on P2020 DS
We implement our own mmc_get_env_addr since the environment variables are
written to just after the u-boot image on SDCard, so we must read the MBR
to get the start address and code length of the u-boot image, then
calculate the address of the env.

abc76eb6a6 ppc/85xx: Map boot page guarded for MP boot
We already map the page cache-inhibited.  There is no reason we
shouldn't also be marking it guarded to prevent speculative accesses.

feb7838f97 85xx: Add P2020DS support
The patch adds support for P2020DS reference platform.
DDR3 interface uses hard-coded initialization rather than SPD
for now and was tested at 667Mhz. Some PIXIS register
definitions and associated code sections need to be fixed.
TSEC1/2/3, NOR flash, MAC/SYS ID EEPROM, PCIE1/2/3 are all
tested under u-boot.
