add-per-board-init-change-qi.patch
Giant patch: - renames everything from kboot to qi - changes filenames accordingly in several places - fixes the linker script so stuff that does not execute from steppingstone context has real linked addresses in the relocated region, it means all code and pointers work now outside first 4KBytes - adds src/gta02/gta02.c to contain board-specific init and other functions - adds sophisticated structs to define most features in the board-specific files, including board type detection, board revision detection, and multiple kernel source definition (NAND, SD FAT, SD ext2, etc), including auto sequencing of trying the kernel sources in order (filesystems and partition support not done yet) - GTA02 detects itself by NOR presence and reports A5 / A6 - commandlines for kernel also come from board-specific kernel source definitions so correct kernel commandlines are provided depending on boot device -- on GTA02 now boots NAND kernel into NAND jffs2 filesystem - CRC32 is checked on loaded kernel image to make sure we know about corruption in bootloader Signed-off-by: Andy Green <andy@openmoko.com>
