From 144fdbdeb1f5cbf3ee99300f7d903da373b0a90d Mon Sep 17 00:00:00 2001 From: George McCollister Date: Thu, 28 Jul 2016 09:49:37 -0500 Subject: x86: som-db5800-som-6867: fix SERIRQ on reset Explicitly enable ILB_SERIRQ function 1 in cfio_regs_pad_ilb_serirq_PCONF0. Pad configuration for SERIRQ is not set to enable the SERIRQ function after a reset though strangely, it is on initial boot. Rebooting from Linux, reset command in u-boot and even pushing the reset button on the development board all lead to the SERIRQ function being disabled (address 0xfed0c560 with value of 0x2003cc80).
