[U-Boot] [PATCH] ppc4xx: Fix initialization of the SDRAM_CODT register

This fixes the initialization of the SDRAM_CODT register in the ppc4xx DDR2 initialization code. It also removes use of the SDRAM_CODT_FEEDBACK_RCV_SINGLE_END and SDRAM_CODT_FEEDBACK_DRV_SINGLE_END #define's since they are reserved bits. Signed-off-by: Carolyn Smith --- diff -uprN old/cpu/ppc4xx

[U-Boot] question about U-Boot's cpu/ppc4xx/44x_spd_ddr2.c

I have a question about some of the code in U-Boot's cpu/ppc4xx/44x_spd_ddr2.c, in particular the program_codt function and these lines of code: mfsdram(SDRAM_CODT, codt); codt |= (SDRAM_CODT_IO_NMODE & (~SDRAM_CODT_DQS_SINGLE_END & ~SDRAM_CODT
