From 9272dcc232b84ccb027d6861077934055d42764d Mon Sep 17 00:00:00 2001 From: Wu Zhangjin Date: Fri, 24 Dec 2010 21:39:08 +0800 Subject: pata_cs5536: Add support for non-X86_32 platforms pata_cs5536 does work on the other platforms(e.g. Loongson, a MIPS variant), so, remove the dependency of X86_32 and fix the building errors under the other platforms via only reserving the X86_32 specific parts for X86_32. pata_amd also supports cs5536 IDE controller, but this one saves about 33k for the compressed kernel image(vmlinuz for MIPS).
