kconfig: move initramfs options to General Setup Move initramfs options from Device Drivers | Block Drivers to General Setup This is a more natural place for this option. Furthermore separate out intramfs options to usr/Kconfig Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

bzip2/lzma: move initrd/ramfs options out of BLK_DEV Impact: Partial resolution of build failure Move the initrd/initramfs configuration options from drivers/block/Kconfig to usr/Kconfig, since they do not and should not depend on CONFIG_BLK_DEV. This fixes builds when CONFIG_BLK_DEV=n. Signed-off-by: H. Peter Anvin <hpa@zytor.com>

usr/Kconfig: make initrd compression algorithm selection not expert The kernel has support for (nearly) every compression algorithm known to man, each to handle some particular microscopic niche. Unfortunately all of these always get compiled in if you want to support INITRDs, and can be only disabled when CONFIG_EXPERT is set. I don't see why I need to set EXPERT just to properly configure the initrd compression algorithms, and not always include every possible algorithm Usually the initrd is just compressed with gzip anyways, at least that's true on all distributions I use. Remove the dependencies for initrd compression on CONFIG_EXPERT. Make the various options just default y, which should be good enough to not break any previous configuration.

bzip2/lzma: move CONFIG_RD_* options under CONFIG_EMBEDDED Impact: reduce Kconfig noise Move the options that control possible initramfs/initrd compressions underneath CONFIG_EMBEDDED. The only impact of leaving these options set to y is additional code in the init section of the kernel; there is no reason to burden non-embedded users with these options. Signed-off-by: H.

bzip2/lzma: make internal initramfs compression configurable Impact: Avoids silent environment dependency Make builtin initramfs compression an explicit configurable. The previous version would pick a compression based on the binaries which were installed on the system, which could lead to unexpected results. It is now explicitly configured, and not having the appropriate binaries installed on the build host is simply an error. Signed-off-by: Alain Knaff <alain@knaff.lu> Signed-off-by: H.

decompressors: add boot-time XZ support This implements the API defined in <linux/decompress/generic.h> which is used for kernel, initramfs, and initrd decompression. This patch together with the first patch is enough for XZ-compressed initramfs and initrd; XZ-compressed kernel will need arch-specific changes. The buffering requirements described in decompress_unxz.c are stricter than with gzip, so the relevant changes should be done to the arch-specific code when adding support for XZ-compressed kernel. Similarly, the heap size in arch-specific pre-boot code may need to be increased (30 KiB is enough). The XZ decompressor needs memmove(), memeq() (memcmp() == 0), and memzero() (memset(ptr, 0, size)), which aren't available in all arch-specific pre-boot environments. I'm including simple versions in decompress_unxz.c, but a cleaner solution would naturally be nicer. Signed-off-by: Lasse Collin <lasse.collin@tukaani.org> Cc: "H.
