[U-Boot] [PATCH 00/10] add boot from NAND/eSDHC/eSPI support

[Mingkai Hu]

The MPC8536E is capable of booting form NAND/eSDHC/eSPI, this patchset
implements these three bootup methods in a unified way - all of these
use the general cpu/mpc85xx/start.S, and load the second stage image
to L2SRAM which lets us use the SPD to initialize the SDRAM.

[PATCH 01/10] mkconfig: parse top level makefile target to multiple config targets
[PATCH 02/10] NAND boot: change NAND loader's relocate SP to CONFIG param
[PATCH 03/10] Add L2SRAM Register's macro definition

[PATCH 04/10] 85xx: add boot from NAND/eSDHC/eSPI support
[PATCH 05/10] NAND boot: MPC8536DS support
[PATCH 06/10] On-chip ROM boot: MPC8536DS support

Add description for the different boot method:
[PATCH 07/10] Add README.mpc8536ds

The follow three patches implement save env to SDCard:
[PATCH 08/10] Make mmc init come before env_relocate
[PATCH 09/10] Add support for save environment variable to MMC/SD card
[PATCH 10/10] Get the address of env on the SDCard
