This patch series adds initial framework for dual format uImage support to U-boot. Booting control flow is reworked and is now able to recognize both formats: legacy format based on a binary image_header stucture and new FIT uImage format based on a libfdt. Legacy specific code is adapted a bit and enterd only for legacy format images. Proper new uImage format handling is not implement in this patch series, appropriate cases are stubed and will be updated with the new uImage format low level code in the comming patchsets.
To sum up: Legacy format image handling shall continue to work, FIT format image handling will produce debug messages and return with error.
Three other patches refactor legacy format specific code to a helper routines image_get_kernel(), image_get_fdt() and move PPC FDT blob relocattion code to a dedicated routine fdt_relocate().
Included are also fixes: reworked gen_get_image() and correced raw FDT blob handling when CONFIG_FIT is disabled.
Please review and comment.
