From a26ee60f90daffe1de6be0d093af86e7279b3dfd Mon Sep 17 00:00:00 2001 From: Alain Knaff Date: Wed, 7 Jan 2009 00:10:27 -0800 Subject: bzip2/lzma: fix built-in initramfs vs CONFIG_RD_GZIP Impact: Resolves build failures in some configurations Makes it possible to disable CONFIG_RD_GZIP . In that case, the built-in initramfs will be compressed by whatever compressor is available (bzip2 or lzma) or left uncompressed if none is available. It also removes a couple of warnings which occur when no ramdisk compression at all is chosen. It also restores the select ZLIB_INFLATE in drivers/block/Kconfig which somehow came missing. This is needed to activate compilation of the stuff in zlib_deflate. Signed-off-by: Alain Knaff Signed-off-by: H.
