[U-Boot] [PATCH 1/2] PPC4xx IBM Memory Controller DDR autocalibration routines.

2008-09-03 Thread Adam Graham
Alternate SDRAM DDR autocalibration routine that can be generically used for any PPC4xx chips that have the IBM SDRAM Controller core allowing for support of more DIMM/memory chip vendors and gets the DDR autocalibration values which give the best read latency performance (SDRAM0_RDCC.[RDSS]). Two
