GP32 An Os For The Gp32

[mithris]

The bootloader doesn't do much, alteast not in the case of linux.
Since the default MMU setup from the BIOS is exactly what the linux kernel wants to boot, 1:1 mapping virtualhysical.

Then i guess it's up to the OS to reconfigure the MMU..
But after reading the docs it appears that there should be no problem with mapping 0x00-> to ram..

i was wandering can we replace the vector handler?
can we remap the BIOS rom area (0x00000-0xfffff)?

Sure you can remap it.. that's no magic just a different mmu setup.

mithris have you take a look at my cvs?
thanx to Jay Monkman (the guys whom made 3 rtems ports for arm) i've made impressive progress...(still not working ofcourse)
in fact if i had the ext connector maybe it would be working right now

in the cvs...
start, startup and irq modules should be ok...(ive drop some doc about the exception vector handling doc)
timers are not required for firsts tests and console module should be allready ok
all we need left is the uart modules(could you take a look please)
and the bootloader which im going to build asap
