Subject: [U-Boot]  socfpga: mainline cannot boot linux

Hi Marek,

Have you been able to successfully boot Linux using the mainline uboot?
I cannot seem to be able to boot linux on the C5 SocDK.

It starts to boot linux, but then reboots after a bit back into u-boot.
So I commented out #define CONFIG_HW_WATCHDOG in
include/configs/socfpga_cyclone5.h. That helped so that I can look that
__log_buf.
I was able to trace it down that it was not able to get a tty console,
because serial8250_console_setup() is failing at:

if (!port->iobase && !port->membase)

For reasons I haven't figured out yet, both port->iobase and
port->membase are NULL.

So no debug console, but Linux is able to boot all the way to the point
of tyring to mount a FS.

Perhaps some kind of memory setup issue? I've seen a thread where
Chin-Liang was able to boot, but I don't know if he did any other tricks.

Just wondering if I'm missing a patch or something?

Thanks,
Dinh
