2007-07-12[ARM] 4393/2: ARMv7: Add uncompressing code for the new CPU Id formatCatalin Marinas
The current arch/arm/boot/compressed/head.S code only supports cores to ARMv6 with the old CPU Id format. This patch adds support for the new ARMv6 with the new CPU Id and ARMv7 cores that no longer have the ARMv4 cache operations.

2007-07-12[ARM] riscpc: fix decompressor font file handlingRussell King
font_acorn_8x8.o was being built in drivers/video/console/ twice during a build _in the same location_ - once for the kernel proper, and once for the decompressor. The result is when you came to run an install target, the kernel was always rebuilt due to this file apparantly having been built with different compiler arguments. Solve this by making a local copy at build time in the decompressor's directory. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2007-07-12[ARM] 4407/1: Remove in-kernel mach id setting for gtwx5715 ixp4xx boardMichael-Luke Jones
If MACH_GTWX5715 is set in Kconfig, this code sets the mach id automatically. Howeber, this means that any IXP4xx kernel which is setup to support the gtwx5715 board will not successfully boot on any other board. If the bootloader sets the wrong mach id, it should be set correctly by a kernel shim. Signed-off-by: Michael-Luke Jones <mlj28@cam.ac.uk> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2007-06-02[ARM] 4392/2: Do not corrupt the SP register in compressed/head.SCatalin Marinas
ARMv7 support code requires a valid stack for saving/restoring registers as the whole D-cache flushing function is more complex. This patch ensures that the SP register is not corrupted.

2006-09-30[ARM] 3809/3: get rid of 4 megabyte kernel image size limitLennert Buytenhek
We currently have a hardcoded 4 megabyte uncompressed kernel image size limit, which is easily exceeded by, for example, enabling some of the various kernel debugging options. When setting up the initial page tables (which is where this 4M limit is hardcoded), it's actually relatively easy to find out the true size of the uncompressed kernel image and create enough page table entries for things to fit, so this patch makes it so. In the decompressor, we also need to know the size of the uncompressed kernel image, to figure out whether there is any chance that uncompressing the kernel might overwrite the compressed kernel image stored elsewhere in memory. We don't have that info at this boot stage, though, so we approximate the size of the uncompressed kernel by taking the compressed kernel image size and allowing for a maximum 4x expansion.

2006-01-12[ARM] Allow r2 to be passed through the decompressor to the kernelRussell King
This is part of a patch from Marc Singer to allow r2 to be passed to the kernel. Marc's original comments follow: This revised R2 (atags pointer) patch incorporates comments from Nico Pitre and Ben Dooks. It modifies the head.S files such that the R2 value set by the bootloader is conveyed to the kernel startup code. The kernel head.S heuristically validates the pointer. It will set R2 to zero if it believes the pointer is invalid. Presently, it requires that the ATAGS list reside in the first 16KiB of physical RAM. Relaxing this contraint may be both desirable as well as tricky. Signed-off-by: Marc Singer <elf@buici.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2005-04-16Linux-2.6.12-rc2Linus Torvalds
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
