Following fix is needed: - swap base addresses in CONFIG_SYS_FLASH_BANKS_LIST, as flash bank 1 is on chipselect 0 and flash bank 2 on chipselect 1 - call fdt_fixup_nor_flash_size() from ft_board_setup() Signed-off-by: Heiko Schocher cc: Wolfgang Denk cc: Werner Pfister cc: Detlev Zundel --- diff --git a/board/digsy_mtc/digsy_mtc.c b/board/digsy_mtc/digsy_mtc.c index afb0948057..cbfdc9edff 100644 --- a/board/digsy_mtc/digsy_mtc.c +++ b/board/digsy_mtc/digsy_mtc.c @@ -46,6 +46,7 @@ #include "is42s16800a-7t.h" #endif #include +#include DECLARE_GLOBAL_DATA_PTR; @@ -415,6 +416,10 @@ void ft_board_setup(void *blob, bd_t *bd) ft_delete_node(blob, "mc,rv3029c2"); #endif #if defined(CONFIG_SYS_UPDATE_FLASH_SIZE) +#ifdef CONFIG_FDT_FIXUP_NOR_FLASH_SIZE + /* Update reg property in all nor flash nodes too */ + fdt_fixup_nor_flash_size(blob); +#endif ft_adapt_flash_base(blob); #endif } diff --git a/include/configs/digsy_mtc.h b/include/configs/digsy_mtc.h index bfbec6a860..e7fd0f7f9c 100644 --- a/include/configs/digsy_mtc.h +++ b/include/configs/digsy_mtc.h @@ -268,8 +268,8 @@ #define CONFIG_SYS_FLASH_BASE 0xFE000000 #define CONFIG_SYS_FLASH_BASE_CS1 0xFC000000 #define CONFIG_SYS_MAX_FLASH_BANKS 2 -#define CONFIG_SYS_FLASH_BANKS_LIST { CONFIG_SYS_FLASH_BASE_CS1, \ - CONFIG_SYS_FLASH_BASE} +#define CONFIG_SYS_FLASH_BANKS_LIST { CONFIG_SYS_FLASH_BASE, \ + CONFIG_SYS_FLASH_BASE_CS1} #define CONFIG_SYS_UPDATE_FLASH_SIZE #define CONFIG_FDT_FIXUP_NOR_FLASH_SIZE #else
