Payload that can do mmio32/pciserial UART on x86

[Alex G.]

Is there such a payload? Seabios is stuck with IO UARTs. Not sure if
grub can handle it (and if so, how). Depthcharge is out of the question
because it is unbelievably difficult to build outside chromium os's
uber-cumbersome build system.

So, is there something?

I would think you could roll your own REPL payload pretty easily w/
libpayload. Aside from that suggestion (go build one!) I don't know of
any.

FILO.

It uses libpayload for drivers which has uart8250_mmio32.c.

Hi Patrick,

Thanks! Someone else had also suggested this in a private email. I have
one thing to say, and one thing only:

AWWWWW YEAAAHHHH!
