Re: [openpsion] Kernel source and bookboot

[David G. <dg...@co...>]

Thanks!

Looking at the patchsets on the website... there's not much there. In the
S7 patch (
http://www.yipton.net/content/psilinuxs7/patch-2.4.2-rmk2-np1-pvs2.gz) I
can see code for handling the keyboard and remapping the framebuffer, which
I assume is already set up by the ROM in order to display the boot progress
bar, but I'd expect to see some other drivers for things like PCMCIA or
even just turning the LEDs on or off. I know that at least some of this
should be generic SA1100 (serial?) but even if the LEDs are wired up to
SA1100 GPIOs there should be some S7-specific code for identifying which
one. Is there another bit I need?

Let me know if you find bookboot!

Regarding Fuzix: entertainingly, it uses a 16-bit value for memory size in
kilobytes, which means it can't handle anything bigger that 64MB. That's a
bit of a shame on a Raspberry Pi but luckily the netbook is smaller than
that. CF interrupts are a shame but as Fuzix does all I/O via busy waits
anyway I doubt it'll be a problem.

What'd be really nice is to see the documentation provided by Psion.
Unfortunately, as I understand it, this is only available to Linux
developers via a special agreement, and Fuzix isn't Linux... now that the
Symbian Foundation is defunct I doubt there's anybody left who could change
the agreement, sadly.
