From 7e3297dc280f88ec0c6619a895f3d449776f952e Mon Sep 17 00:00:00 2001 From: Thomas Bogendoerfer Date: Fri, 27 Jun 2008 23:52:26 +0200 Subject: [MIPS] IP22: Fix crashes due to wrong L1_CACHE_BYTES The introduction of a real dma cache invalidate makes it important to have a correct cache line size, otherwise the kernel will gives out two memory segment, which might share one cache line. The R4400 Indy/Indigo2 CPU modules are using a second level cache line size of 128 bytes, so MIPS_L1_CACHE_SHIFT needs to be bumped up to 7 for IP22.
