From 58e5585625d06530cf52ffc2b7b9a188dc46bffe Mon Sep 17 00:00:00 2001 From: Francois Retief Date: Mon, 23 Nov 2015 09:49:57 +0200 Subject: [PATCH] sparc: leon3: Clear GD_FLAG_SERIAL_READY flag on AMBA failure Clear the GD_FLG_SERIAL_READY flag on AMBA P&P lookup failure so that the panic function can use DEBUG_UART driver. drivers/serial/serial.c set this flag before calling this function, preventing DEBUG_UART code from running.
