I think it could also be useful to be able to produce just the boot header without the U-boot image. For example if you want to place U-boot at some other location on the flash or (as a developer) frequently re-flash U-boot, but don't want to write to the first block all the time (you only need to rewrite it when moving U-boot).
Perhaps something like
+Typical example of kwimage.cfg file: +-----------------------------------
+# Boot Media configurations +BOOT_FROM nand +NAND_ECC_MODE default +NAND_PAGE_SIZE 0x0800
SOURCE_OFFSET 0x0 # Relative to the header or NAND start?
+static void kwbimage_set_header (void *ptr, struct stat *sbuf, int ifd,
struct mkimage_params *params)+{
- struct kwb_header *hdr = (struct kwb_header *)ptr;
[...]
- mhdr->srcaddr = sizeof(struct kwb_header);
and this could then be changed to have this info.
