My apologies, this is misleading/incorrect. Rebooting from Linux, reset command in u-boot and even pushing the reset button on the development board all lead to this condition (address 0xfed0c560 with value of 0x2003cc80). On first boot, address 0xfed0c560 has a value of 0x2003cc81 (SERIRQ function selected). I'll update the commit message, add your reviewed-by and post a v2. > >> Signed-off-by: George McCollister <george.mccollister@gmail.com> >> --- >> arch/x86/dts/baytrail_som-db5800-som-6867.dts | 6 ++++++ >> 1 file changed, 6 insertions(+) >> > > Reviewed-by: Bin Meng <bmeng.cn@gmail.com>
