Yann Vernier - Aug. 9, 2012, 1:33 p.m.
Leave dram_init_banksize to set up the bank info data.
ram_size was previously uninitialized.
Also put data on SDRAM configuration in header file.

Changes for v2:
   - Update to use CONFIG_SYS_SDRAM_ constants
   - Update cm41xx also
   - Map SDRAM to match configuration
Changes for v3:
   - Moved SDRAM configuration to header file, in
     preparation for lowlevel constant cleanup.
