From 9966db25defba4e1dce263246db25237bc24479f Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Thu, 11 Oct 2007 23:46:17 +0100 Subject: [PATCH] [MIPS] Make facility to convert CPU types to strings generally available. So far /proc/cpuinfo has been the only user but human readable processor name are more useful than that for proc.
