Re: [U-Boot] [Patch v3 4/7] mpc85xx: Adding more registers and options

This patch exposes more registers which can be used by the DDR drivers or interactive debugging. U-boot doesn't use all the registers in DDRC. When advanced tuning is required, writing to those registers is needed.

Add writing to cdr1, cdr2, err_disable, err_int_en and debug registers Add options to override rcw, address parity to RDIMMs. Use array for debug registers.
