[PATCH] ARM: 2644/1: Adds S3C2400 support to uncompress.h
Patch from Lucas Correia Villa Real The S3C2400 doesn't have a cpuid information stored anywhere. This patch adds support to the S3C2400 at include/asm-arm/arch-s3c2400/uncompress.h by initializing the cpuid variable to the S3C2410, as they share the same routine. The GSTATUS1 pin is then used only if not compiling for the S3C2400. Signed-off-by: Lucas Correia Villa Real Signed-off-by: Ben Dooks Signed-off-by: Russell King
