Hi guys,
I answer to myself. I solved this part of the issue.
First, referring to: http://www.coreboot.org/Memtest86, I built a
coreboot including memtest86+ as payload.
Then, using cbfstool I extracted it to a file, ignoring the warning
concerning the raw type.
At last, rebuild a coreboot with seabios as payload, and add the
previous file with cbfstool as another payload.
That way, in combination with sgabios, I'm able to boot the Mohon Peak,
'ESC' to the boot menu and choose the 'Memtest86+' entry.
The RAM test is then performing in a loop.
What remains to fix is the keyboard entry through the serial link in
order to access to the memtest86+ menu...
(Almost the same as in
http://www.coreboot.org/pipermail/coreboot/2015-February/079173.html)
Hope it helps.
Regards,
Patrick agrain
