[coreboot] EP80579 Mainboard support

[Arnaud Maye]

Hello Again,

I've just received my UART dongle and I could see that indeed something 
has been sent over UART.

The first error seen was about the fact only ECC DIMMs are allowed, in 
the devkit they provide
non-ecc memory. Is it normal coreboot only supports ECC DIMMs?

I've then plugged some nice kingston DIMM with ecc and what I get then 
is an exception :

Unexpected Exception: 13 @ 10:00002f08 - Halting
Code: 4096 eflags: 00010282
eax: 002163b6 ebx: 0000c000 ecx: 0000227e edx: fffffffe
edi: 0000eb02 esi: 0000f444 ebp: 0000bebc esp: 0000bebc

As soon I get this exception, the 7 segments display : FF

I guess if this is the first thing I get, coreboot has a problem not the 
payload, right?

Could you tell me which coreboot version from the 1.3 tree you have been 
using when you
validated the port?

Thank you.

Arnaud
