Basically it's 2 questions:
1) Does eCos run on Yeeloong at all?
2) Does it support initrd-only operation mode?

Only 1MiB of adressing space on Yeeloong is reserved for boot rom. I
don't know how many address lines are actually connected. So we're
limited to either 512KiB or 1MiB. There is also a mention of LIO ROM
with 32MiB of addressing space reserved for it. I haven't looked yet if
it's actually present and how it's used on Yeeloong
