Arrange the code to fix this. Note: The question was raised as to why we don't keep all archs in sync. PowerPC doesn't have specific bootstage markers at present (although it does use boot progress). I hope that the generic board series will solve this problem in general, but in the meantime this is a real problem, and only in ARM. We now get a correct time for board_init_f: Timer summary in microseconds: Mark Elapsed Stage 0 0 reset 100,000 100,000 spl_start 848,530 748,530 board_init_f 907,301 58,771 board_init_r 910,478 3,177 board_init Signed-off-by: Simon Glass --- diff --git a/arch/arm/lib/board.c b/arch/arm/lib/board.c index ec5c35f131..404ef4dceb 100644 --- a/arch/arm/lib/board.c +++ b/arch/arm/lib/board.c @@ -232,8 +232,17 @@ int __power_init_board(void) int power_init_board(void) __attribute__((weak, alias("__power_init_board"))); + /* Record the board_init_f() bootstage (after arch_cpu_init()) */ +static int mark_bootstage(void) +{ + bootstage_mark_name(BOOTSTAGE_ID_START_UBOOT_F, "board_init_f"); + + return 0; +} + init_fnc_t *init_sequence[] = { arch_cpu_init, /* basic arch cpu dependent setup */ + mark_bootstage, #ifdef CONFIG_OF_CONTROL fdtdec_check_fdt, #endif @@ -277,8 +286,6 @@ void board_init_f(ulong bootflag) void *new_fdt = NULL; size_t fdt_size = 0; - bootstage_mark_name(BOOTSTAGE_ID_START_UBOOT_F, "board_init_f"); - memset((void *)gd, 0, sizeof(gd_t)); gd->mon_len = _bss_end_ofs;
