ppc: Fix ppc4xx CONFIG_SYS_GENERIC_BOARD
I realized that with v2014.10 u-boot is not starting up on ppc4xx boards with CONFIG_SYS_GENERIC_BOARD set. I bisected it down to this: d54d7eb support blackfin board initialization in generic board_f With d29437a ppc: Make ppc4xx ready for CONFIG_SYS_GENERIC_BOARD I set gd to a defined value for ppc4xx in cpu_init_f(). I did not realize that the gd struct has also to be memset() to zero at this point. But at least commit d54d7eb assumes it is: @@ -516,11 +528,13 @@ static int reserve_malloc(void) /* (permanently) allocate a Board Info struct */ static int reserve_board(void) { - gd->start_addr_sp -= sizeof(bd_t); - gd->bd = (bd_t *)map_sysmem(gd->start_addr_sp, sizeof(bd_t)); - memset(gd->bd, '\0', sizeof(bd_t)); - debug("Reserving %zu Bytes for Board Info at: %08lx\n", - sizeof(bd_t), gd->start_addr_sp); + if (!gd->bd) { + gd->start_addr_sp -= sizeof(bd_t); + gd->bd = (bd_t *)map_sysmem(gd->start_addr_sp, sizeof(bd_t)); + memset(gd->bd, '\0', sizeof(bd_t)); + debug("Reserving %zu Bytes for Board Info at: %08lx\n", + sizeof(bd_t), gd->start_addr_sp); + } return 0; } #endif This might also be an issue on other architectures, so maintainers should check.
