* Empirically set cpo and clk_adjust for mpc85xx DDR2 supportHaiying Wang2007-08-141-5/+7
| | | | | | | | | | | | | | This patch is against u-boot-mpc85xx.git of www.denx.com Setting cpo to 0x9 for frequencies higher than 333MHz is verified on both MPC8548CDS board and MPC8568MDS board, especially for supporting 533MHz DDR2. Setting clk_adjust to 0x6(3/4 late cycle) for MPC8568MDS board is for DDR2 on all current board versions especially ver 1.92 or later to bring up.

* MPC85xx BA bits not set for 3-bit bank address DIMMAndy Fleming2007-08-141-1/+6
| | | | | | | | | | The current implementation does not set the number of bank address bits (BA) in the processor. The default assumes 2 logical bank bits. This works fine for a DIMM that uses devices with 4 internal banks (SPD byte17 = 0x4) but needs to be set appropriately for a DIMM that uses devices with 8 internal banks (SPD byte17 = 0x8).
