- defines contants
- Add spl_minimal.c to initialise DDR
- update TLB entries as per NAND boot
- remove nand_spl support for P1010RDB
Signed-off-by: Prabhakar Kushwaha <prabhakar(a)freescale.com>
---
Based upon git://git.denx.de/u-boot.git branch master
Changes for v2:
- Define CONFIG_A003399_NOR_WORKAROUND for NOR boot
Changes for v3:
- Put CONFIG_A003399_NOR_WORKAROUND in CONFIG_SYS_FSL_ERRATUM_IFC_A003399
- Fix tools/checkpatch errors
