If anyone has any objections, please let me know. ------------------ From: Rajendra Nayak 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.
