[RFC PATCH 2/2] ARM: OMAP4: setup CPU model name during ID initialisation

From: Ruslan Bilovol
Date: Tue Jan 29 2013 - 10:54:56 EST


Set up the CPU model name during OMAP ID initialisation
so it will be displayed in /proc/cpuinfo:

/ # cat proc/cpuinfo
processor : 0
model name : ARMv7 Processor rev 10 (v7l)
BogoMIPS : 1590.23
Features : swp half thumb fastmult vfp edsp thumbee neon vfpv3 tls
CPU implementer : 0x41
CPU name : OMAP4470 ES1.0 HS
CPU architecture: 7
CPU variant : 0x2
CPU part : 0xc09
CPU revision : 10
[...]
