ARM: 5884/1: arm: Fix DCC console for v7
Without this patch arch/arm/compressed/head.S defaults to generic
DCC code that does not work for v7.
For more information on the v7 DCC, see Cortex-A8 TRM
"12.11.1 Debug communications channel".
To use it with post 2.6.33-rc1 or later, you need to have:
CONFIG_DEBUG_LL=y
ONFIG_DEBUG_ICEDCC=y
CONFIG_EARLY_PRINTK=y
Earlier kernels need commit 93fd03a8c6728b58879f8af20ffd55d9c32a778b
backported.
Tested on omap3430.
