f28bea0003 eSDHC: Calculate envaddr accroding to the address format
On BSC9131, BSC9132, P1010 : For High Capacity SD Cards (> 2 GBytes), the
32-bit source address specifies the memory address in block address
format. Block length is fixed to 512 bytes as per the SD High Capacity
specification. So we need to convert the block address format
to byte address format to calculate the envaddr.

If there is no enough space for environment variables or envaddr
is larger than 4GiB, we relocate the envaddr to 0x400. The address
relocated is in the front of the first partition that is assigned
for sdboot only.

d196bd8803 env_mmc: add support for redundant environment
This patch add support for storing the environment redundant on
mmc devices. Substantially it re-uses the logic from the NAND implementation,
that means using an incremental counter for marking newer data.

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.
