[PATCH 3/3] omap4: SRAM start and size change for EMU/HS devices

[Vikram Pandita]

On OMAP4 the SRAM configuration is:
GP Device:
        Start Address: 0x4030 0000
        Size: 0xE000 (56KB)

EMU/HS Device:
        Start Address: 0x4030 4000
        Size: 0xA000 (40KB)

Implement this mapping in the sram file
