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 93fd03a8 backported. Tested on omap3430.
