Fabio Estevam - June 2, 2011, 7:26 p.m.
This fixes the MX31ADS build by using the new relocation scheme.

Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>
---
Changes since v2:
- Use PHYS_SDRAM_1 in get_ram_size
- Remove local config.mk

Changes since v1:

- Fixed lines over 80 characters.

Build tested only.

Do not have the hardware handy to test.
