If the image is found, it will return CMD_RET_SUCCESS, else CMD_RET_FAILURE. This allows hush scripts to conditionally load images. A simple example: if afs exists ${kernel_name}; then echo found; else echo \ not found; fi Signed-off-by: Ryan Harkin Reviewed-by: Linus Walleij --- common/cmd_armflash.c | 22 +++++++++++++++++++++- 1 file changed, 21 insertions(+), 1 deletion(-) diff --git a/common/cmd_armflash.c b/common/cmd_armflash.c index 1db92b0..a37f5c4 100644 --- a/common/cmd_armflash.c +++ b/common/cmd_armflash.c @@ -251,10 +251,28 @@ static void print_images(void) } } +static int exists(const char * const name) +{ + int i; + + parse_flash(); + for (i = 0; i < num_afs_images; i++) { + struct afs_image *afi = &afs_images[i]; + + if (strcmp(afi->name, name) == 0) + return CMD_RET_SUCCESS; + } + return CMD_RET_FAILURE; +} + static int do_afs(cmd_tbl_t *cmdtp, int flag, int argc, char * const argv[]) { + int ret = CMD_RET_SUCCESS; + if (argc == 1) { print_images(); + } else if (argc == 3 && !strcmp(argv[1], "exists")) { + ret = exists(argv[2]); } else if (argc == 3 && !strcmp(argv[1], "load")) { load_image(argv[2], 0x0); } else if (argc == 4 && !strcmp(argv[1], "load")) { @@ -266,12 +284,14 @@ static int do_afs(cmd_tbl_t *cmdtp, int flag, int argc, char * const argv[]) return CMD_RET_USAGE; } - return 0; + return ret; } U_BOOT_CMD(afs, 4, 0, do_afs, "show AFS partitions", "no arguments\n" " - list images in flash\n" + "exists \n" + " - returns 1 if an image exists, else 0\n" "load \n" " - load an image to the location indicated in the header\n" "load 0x
