From mboxrd@z Thu Jan 1 00:00:00 1970 From: lokeshvutla@ti.com (Lokesh Vutla) Date: Tue, 6 Jan 2015 13:54:50 +0530 Subject: [PATCH] ARM: DRA7: beagle-x15: hwmod: Fix boot crash with DEBUG_LL Message-ID: <1420532690-29340-1-git-send-email-lokeshvutla@ti.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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 beagle-x15, we use uart3 for console and missed enabling this flag for uart3 hwmod, so boot fails with DEBUG_LL. Enable DEBUG_OMAP4UART3_FLAGS for uart3 hwmod. For using DEBUG_LL, enable CONFIG_DEBUG_OMAP4UART3 in menuconfig.
