Hi,
this is the reference source for the lasat platforms.
I have cleaned up the original code to give a patch which
applies against todays tree and produces a running kernel
on both platforms.
The patch adds (v)r5000 cache support, the general stuff
required to add a new platform and some small patches
in various places to fix bugs and add, for example, mtd
support for the flash in these machines.
The files not patched (not existing in the oss CVS) are
in lasat.tar.gz. This includes arch/mips/lasat and
include/asm-mips/lasat - one file to support r5000 cache
support and one for the memory mapped flash modules
to give mtd support. In addition there are two drivers for
the rtc and display in the two machines which have
interface include files in include/linux.
I know I was encouraged to split up this stuff but I could
spend weeks or months doing that and not have something
which would satisfy the authorities - This is my first attempt.
Perhaps, Florian, you can look at it and give me some advice
as to how I should structure any splitting-up to get this
accepted.
If anyone has a masquerade (or safepipe) box then you will
also need the information on http://debian.murphy.dk to get
this stuff uploaded on your box. Any problems, send me a
mail.
regards
/Brian
