Subject: UBI: Add compile-time check for correct malloc area configuration
X-Git-Tag: v2009.08-rc1~153^2~29
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=60cfe87bd39e6f07f2b92eb4bff82bfd105f4724;p=platform%2Fkernel%2Fu-boot.git

UBI: Add compile-time check for correct malloc area configuration

UBI is quite memory greedy and requires at least approx. 512k of malloc
area. This patch adds a compile-time check, so that boards will not
build with less memory reserved for this area (CONFIG_SYS_MALLOC_LEN).
