From b009f3eca99bb7b9e6ba6639a8909a138dd5e9fe Mon Sep 17 00:00:00 2001 From: Kumar Gala Date: Tue, 8 Jan 2008 01:22:21 -0600 Subject: 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.
