ARM: 6999/1: head, zImage: Always Enter the kernel in ARM state

2011-07-19T11:00:53Z

Currently, the documented kernel entry requirements are not explicit about whether the kernel should be entered in ARM or Thumb, leading to an ambiguitity about how to enter Thumb-2 kernels. As a result, the kernel is reliant on the zImage decompressor to enter the kernel proper in the correct instruction set state. This patch changes the boot entry protocol for head.S and Image to be the same as for zImage: in all cases, the kernel is now entered in ARM. Documentation/arm/Booting is updated to reflect this new policy. A different rule will be needed for Cortex-M class CPUs as and when support for those lands in mainline, since these CPUs don't support the ARM instruction set at all: a note is added to the effect that the kernel must be entered in Thumb on such systems.

The PORT_S3C2400 definition in include/linux/serial_core.h is left there to prevent a reuse of the same number for another port type. Signed-off-by: Nicolas Pitre Acked-by: Arnd Bergmann

ARM: 6886/1: mmc, Add zboot from eSD support for SuperH Mobile ARM

2011-06-29T09:00:52Z

This allows a ROM-able zImage to be written to eSD and for SuperH Mobile ARM to boot directly from the SDHI hardware block. This is achieved by the MaskROM loading the first portion of the image into MERAM and then jumping to it. This portion contains loader code which copies the entire image to SDRAM and jumps to it. From there the zImage boot code proceeds as normal, uncompressing the image into its final location and then jumping to it.

ARM: add a kuser_cmpxchg64 user space helper

2011-06-28T19:47:47Z

Some user space applications are designed around the ability to perform atomic operations on 64 bit values. Since this is natively possible only with ARMv6k and above, let's provide a new kuser helper to perform the operation with kernel supervision on pre ARMv6k hardware.

ARM: kuser: move interface documentation out of the source code

2011-06-20T14:49:24Z

Digging into some assembly file in order to get information about the kuser helpers is not that convivial. Let's move that information to a better formatted file in Documentation/arm/ and improve on it a bit. Thanks to Dave Martin for the initial cleanup and clarifications.
