Date: Mon, 6 Jan 2014 14:36:46 -0800 From: Greg Kroah-Hartman <gregkh@...uxfoundation.org> To: linux-kernel@...r.kernel.org Cc: Greg Kroah-Hartman <gregkh@...uxfoundation.org>, stable@...r.kernel.org, Lokesh Vutla <lokeshvutla@...com>, Rajendra Nayak <rnayak@...com>, Paul Walmsley <paul@...an.com> Subject: [PATCH 3.12 045/144] ARM: DRA7: hwmod: Fix boot crash with DEBUG_LL 3.12-stable review patch. If anyone has any objections, please let me know. ------------------ From: Rajendra Nayak <rnayak@...com> commit 38958c15dc640a9249e4f0cd0dfb0ddc7a23464d upstream. With commit '7dedd34: ARM: OMAP2+: hwmod: Fix a crash in _setup_reset() with DEBUG_LL' we moved from parsing cmdline to identify uart used for earlycon to using the requsite hwmod CONFIG_DEBUG_OMAPxUARTy FLAGS. On DRA7 though, we seem to be missing this flag, and atleast on the DRA7 EVM where we use uart1 for console, boot fails with DEBUG_LL enabled.
