Revised patch is attached. - add some comments on L2 cache, - and cache.S is no longer 4K specific routines now! ================> [MIPS] Extend MIPS_MAX_CACHE_SIZE upto 64kB From: Shinya Kuribayashi <[EMAIL PROTECTED]> Signed-off-by: Shinya Kuribayashi <[EMAIL PROTECTED]> --- cpu/mips/cache.S | 14 +++++++++----- 1 files changed, 9 insertions(+), 5 deletions(-) diff --git a/cpu/mips/cache.S b/cpu/mips/cache.S index e6f3175..89ada71 100644 --- a/cpu/mips/cache.S +++ b/cpu/mips/cache.S @@ -1,5 +1,5 @@ /* - * Cache-handling routined for MIPS 4K CPUs + * Cache-handling routined for MIPS CPUs * * Copyright (c) 2003 Wolfgang Denk <[EMAIL PROTECTED]> * @@ -32,10 +32,14 @@ #define RA t8 - /* 16KB is the maximum size of instruction and data caches on - * MIPS 4K. - */ -#define MIPS_MAX_CACHE_SIZE 0x4000 +/* + * 16kB is the maximum size of instruction and data caches on MIPS 4K, + * 64kB is on 4KE, 24K, 5K, etc. Set bigger size for convenience. + * + * Note that the above size is the maximum size of primary cache.
