Subject: [U-Boot] [PATCH 1/2] 85xx: Use CONFIG_SYS_CACHELINE_SIZE instead of magic number
Date: Thu, 23 Oct 2008 01:47:37 -0500	[thread overview]
Message-ID: <1224744458-15481-1-git-send-email-galak@kernel.crashing.org> (raw)

Using CONFIG_SYS_CACHELINE_SIZE instead of 31 means we can handle
e500mc's 64-byte cacheline properly when it gets added.
