| | | | | | | | | EP93xx: The system controller register definition doesn't take into account a 4 byte gap between ChipId and SysCfg, in consequence all accesses to syscon registers ahead of ChipId fail. Fix this by inserting a filler field Signed-off-by: Matthias Kaehlcke <matthias@kaehlcke.net> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | These cache functions have been extracted from arch/arm/boot/compressed/head.S. The old code only worked properly on ARMv4. Tested on ARMv4, ARMv5, ARMv6 hardware. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | Using these macros simplify the configuration for special GPIO usage. But they should use correct bit positions for usage in the IOMUX_PAD() macro. Note: These are the bit positions of the i.MX35 CPU. Not checked for the other i.MX3x CPUs. Signed-off-by: Juergen Beisert <jbe@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Other architectures are supporting the uImage format used by barebox's 'bootm' command. x86 does'nt. So, we need a special command to be able to boot the x86 specific bzImage format. Signed-off-by: Juergen Beisert <jbe@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is a low level disk drive communication driver. It uses the real mode BIOS found on most x86 platforms, to read and write sectors. Used by the generic disk driver.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This code adds a generic x86 platform, enabling barebox to act as a bootloader like 'GRUB'. Very minimalistic, yet.
