Re: GP2X hardware platform

Hi John,

So, about kernel, we just could port 2.4 kernel to 2.6 and there would
be no problem besides that closed firmware that runs on the other
processor without MMU (/dev/dualcore).

About bootloader, the same bootloader that boots now could be used
boot armel kernel, don't you think? As debian-arm is little endian
stuff and debian-armel is little endian stuff with a new EABI, and the
kernel is the one that understand about those things. (Is that right
or i might be missing some point).

Regards,
Hector Oron
