ARM: decompress: remove unused ARCH_HAS_DECOMP_WDOG

2013-01-11T02:53:55+00:00

ARCH_HAS_DECOMP_WDOG is only used in lib/inflate.c which is not included in arch/arm/boot/compressed/decompress.c now. That said, ARCH_HAS_DECOMP_WDOG is not used at all. Let's remove it. Signed-off-by: Shawn Guo Acked-by: Nicolas Pitre

ARM: 7492/1: add strstr declaration for decompressors

2012-08-25T08:22:30+00:00

With the generic unaligned.h, more kernel headers get pulled in including dynamic_debug.h which needs strstr. As it is not really used, we only need a declaration here. Signed-off-by: Rob Herring Tested-by: Thomas Petazzoni Reviewed-by: Arnd Bergmann Signed-off-by: Russell King

ARM: zImage: don't ignore error returned from decompress()

If decompress() returns an error without calling error(), we must not attempt to boot the resulting kernel. Signed-off-by: Nicolas Pitre Tested-by: Shawn Guo Tested-by: Tony Lindgren

ARM: 6026/1: ARM: Add support for LZMA-compressed kernel images

2010-04-14T11:05:36+00:00

This patch allows using a kernel image compressed with LZMA on ARM. Extracting the image is fairly slow, but it might be useful on machines with a very limited amount of storage, as the size benefit is quite significant (about 25% smaller with LZMA compared to GZIP) Tested-by: Martin Michlmayr Tested-by: Paulius Zaleckas Signed-off-by: Albin Tonnerre Signed-off-by: Russell King

ARM: Add final piece to fix XIP decompressor in read-only memory

2010-03-15T14:29:22+00:00

This defines STATIC_RW_DATA, which prevents the read/write malloc management data being declared with a static attribute. Signed-off-by: Russell King

ARM: Eliminate decompressor -Dstatic= PIC hack

2010-02-25T19:34:31+00:00

We used to build decompressors with -Dstatic= to avoid any local data being generated. The problem is that local data generates GOTOFF relocations, which means we can't relocate the data relative to the text segment. Global data, on the other hand, goes through the GOT, and can be relocated anywhere. Unfortunately, with the new decompressors, this presents a problem since they declare static data within functions, and this leads to stack overflow. Fix this by separating out the decompressor code into a separate file, and removing 'static' from BSS data in misc.c. Also, discard the .data section - this means that should we end up with read/write initialized data, the decompressor will fail to link and the problem will be obvious.
