From f13e7b2e993c61fed1f607962501e051940d6e80 Mon Sep 17 00:00:00 2001 From: Marian Balakowicz Date: Tue, 8 Jan 2008 18:12:17 +0100 Subject: [new uImage] Cleanup image header pointer use in bootm code - use single image header pointer instead of a set of auxilliary variables. - add multi component image helper routines: get component size/data address Signed-off-by: Marian Balakowicz --- lib_microblaze/microblaze_linux.c | 71 +++++++++++++++------------------------ 1 file changed, 28 insertions(+), 43 deletions(-) (limited to 'lib_microblaze') diff --git a/lib_microblaze/microblaze_linux.c b/lib_microblaze/microblaze_linux.c index 7cd97995e..a4fce5a73 100644 --- a/lib_microblaze/microblaze_linux.c +++ b/lib_microblaze/microblaze_linux.c @@ -32,21 +32,21 @@ DECLARE_GLOBAL_DATA_PTR; -extern image_header_t header; /* from cmd_bootm.c */ -/*cmd_boot.c*/ extern int do_reset (cmd_tbl_t * cmdtp, int flag, int argc, char *argv[]); void do_bootm_linux (cmd_tbl_t * cmdtp, int flag, int argc, char *argv[], - ulong addr, ulong * len_ptr, int verify) + image_header_t *hdr, int verify) { - ulong len = 0, checksum; + int i; + ulong checksum; + + ulong rd_data, rd_len; ulong initrd_start, initrd_end; - ulong data; + image_header_t *rd_hdr; + /* First parameter is mapped to $r5 for kernel boot args */ void (*theKernel) (char *); - image_header_t *hdr = &header; char *commandline = getenv ("bootargs"); - int i; theKernel = (void (*)(char *))image_get_ep (hdr); @@ -54,33 +54,30 @@ void do_bootm_linux (cmd_tbl_t * cmdtp, int flag, int argc, char *argv[], if (argc >= 3) { show_boot_progress (9); - addr = simple_strtoul (argv[2], NULL, 16); - hdr = (image_header_t *)addr; + rd_hdr = (image_header_t *)simple_strtoul (argv[2], NULL, 16); + printf ("## Loading Ramdisk Image at %08lx ...\n", rd_hdr); - printf ("## Loading Ramdisk Image at %08lx ...\n", addr); - - if (!image_check_magic (hdr)) { + if (!image_check_magic (rd_hdr)) { printf ("Bad Magic Number\n"); show_boot_progress (-10); do_reset (cmdtp, flag, argc, argv); } - if (!image_check_magic (hdr)) { + if (!image_check_magic (rd_hdr)) { printf ("Bad Header Checksum\n"); show_boot_progress (-11); do_reset (cmdtp, flag, argc, argv); } show_boot_progress (10); + print_image_hdr (rd_hdr); - print_image_hdr (hdr); - - data = image_get_data (hdr); - len = image_get_data_size (hdr); + rd_data = image_get_data (rd_hdr); + rd_en = image_get_data_size (rd_hdr); if (verify) { printf (" Verifying Checksum ...
