From 566a494f592ae3b3c0785d90d4e1ba45574880c4 Mon Sep 17 00:00:00 2001 From: Heiko Schocher Date: Fri, 22 Jun 2007 19:11:54 +0200 Subject: [PCS440EP] upgrade the PCS440EP board: - Show on the Status LEDs, some States of the board. - Get the MAC addresses from the EEProm - use PREBOOT - use the CF on the board. - check the U-Boot image in the Flash with a SHA1 checksum. - use dynamic TLB entries generation for the SDRAM Signed-off-by: Heiko Schocher --- cpu/ppc4xx/44x_spd_ddr.c | 26 +++++++++++++++++--------- 1 file changed, 17 insertions(+), 9 deletions(-) (limited to 'cpu/ppc4xx/44x_spd_ddr.c') diff --git a/cpu/ppc4xx/44x_spd_ddr.c b/cpu/ppc4xx/44x_spd_ddr.c index c500d3f..8621aa0 100644 --- a/cpu/ppc4xx/44x_spd_ddr.c +++ b/cpu/ppc4xx/44x_spd_ddr.c @@ -70,6 +70,13 @@ #define ONE_BILLION 1000000000 +#if defined(CONFIG_PPC4xx_USE_SPD_DDR_INIT_HANG) +extern void spd_ddr_init_hang (void); +#define HANG() spd_ddr_init_hang() +#else +#define HANG() hang() +#endif + /*----------------------------------------------------------------------------- | Memory Controller Options 0 +-----------------------------------------------------------------------------*/ @@ -467,7 +474,7 @@ static void get_spd_info(unsigned long *dimm_populated, if (dimm_found == FALSE) { printf("ERROR - No memory installed.
