-/***********************************************************************
- * Configure Memory Map
- *
- * This memory map allows us to relocate from FLASH to SRAM. After
- * power-on reset the CPU only knows about the FLASH memory at address
- * 0x00000000. After lowlevel_init completes the memory map will be:
- *
- * Memory Addr
- * 0x00000000
- * to 8MB SRAM (U5) -- 8MB Map
- * 0x00800000
- *
- * 0x01000000
- * to 2MB Flash @ 0x00000000 (U7) -- 2MB Map
- * 0x01200000
- *
- * 0x02000000
- * to 512KB Flash @ 0x02000000 (U9) -- 2MB Map
- * 0x02080000
- *
- * Load all 12 memory registers with the STMIA instruction since
- * memory access is disabled once these registers are written. The
- * last register written re-enables memory access. For more info see
- * the user's manual for the S3C4510B, available from Samsung's web
- * site. Search for part number "S3C4510B".
