ppc4xx: Changed 460EX/GT OCM TLB and internal SRAM initialization
Expanded OCM TLB to allow access to 64K OCM as well as 256K of internal SRAM. Adjusted internal SRAM initialization to match updated user manual recommendation. OCM & ISRAM are now mapped as follows: physical virtual size ISRAM 0x4_0000_0000 0xE300_0000 256k OCM 0x4_0004_0000 0xE304_0000 64k A single TLB was used for this mapping.
