From: Kumar Gala Date: Tue, 8 Jan 2008 07:22:21 +0000 (-0600) Subject: 85xx: Remove cache config from configs.h X-Git-Tag: v1.3.2-rc1~102^2~37^2~3 X-Git-Url: https://git.sur5r.net/?a=commitdiff_plain;h=b009f3eca99bb7b9e6ba6639a8909a138dd5e9fe;p=u-boot 85xx: Remove cache config from configs.h Either use the standard defines in asm/cache.h or grab the information at runtime from the L1CFG SPR. Also, minor cleanup in cache.h to make the code a bit more readable.
