From abbe536ebc3ee974593b115de716705f0091344a Mon Sep 17 00:00:00 2001 From: Matthew McClintock Date: Mon, 13 Aug 2012 08:10:39 +0000 Subject: powerpc/p1010rdb: nandboot: compare SVR properly We were not comparing the SVRs properly previously. This comparison will properly shift the SVR and mask off the E bit This fixes the boot output to show the correct DDR bus width: 512 MiB (DDR3, 16-bit, CL=5, ECC off) instead of 512 MiB (DDR3, 32-bit, CL=5, ECC off) Signed-off-by: Matthew McClintock Signed-off-by: Andy Fleming --- nand_spl/board/freescale/p1010rdb/nand_boot.c | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'nand_spl') diff --git a/nand_spl/board/freescale/p1010rdb/nand_boot.c b/nand_spl/board/freescale/p1010rdb/nand_boot.c index 1f89ab5..f5294d0 100644 --- a/nand_spl/board/freescale/p1010rdb/nand_boot.c +++ b/nand_spl/board/freescale/p1010rdb/nand_boot.c @@ -35,7 +35,8 @@ unsigned long ddr_freq_mhz; void sdram_init(void) { ccsr_ddr_t *ddr = (ccsr_ddr_t *)CONFIG_SYS_MPC85xx_DDR_ADDR; - u32 svr = mfspr(SPRN_SVR); + /* mask off E bit */ + u32 svr = SVR_SOC_VER(mfspr(SPRN_SVR)); out_be32(&ddr->sdram_cfg, CONFIG_SYS_DDR_CONTROL | SDRAM_CFG_32_BE); out_be32(&ddr->cs0_bnds, CONFIG_SYS_DDR_CS0_BNDS); -- cgit v1.1
