Subject: [PATCH v3] ARM: bcm: Add DEBUG_LL console support
Date: Sat,  5 Oct 2013 08:43:29 -0700	[thread overview]
Message-ID: <1380987809-4886-1-git-send-email-bcm@fixthebug.org> (raw)

This patch adds low level debug uart support to Broadcom
 mobile based SOCs.

Signed-off-by: Christian Daudt <bcm@fixthebug.org>

Changes from V2:
 - Changed to follow hex ordering on entries
 - Dropped defconfig changes

Changes from V1:
 - Switched to use the common 8250 debug introduced in 3.12-rc1
