Really nice looking board guys ...
But I hope you consider releasing a later kernel; 2.6.12 is over two
years old already. Most of the cool arm stuff is much more recent:
HRT, tickless kernel, preempt, EABI (the biggie, appeared in 2.6.18
or .19 I believe), etc. EABI is really needed to get the best FP
out of the ARMs with linux. To put it in perspective, this massive
hardware change brings 3X performance, but (for FP users) EABI &
softfloat bring 12X performance increase with no HW change.
There's a group of people porting current linux kernels to the
Buffalo LinkStation NAS boxes & clones (also Marvell Orion-1,
88F4182(?), with AVR, looks very close to the TS-7800). They
haven't gotten any help from Marvell though ... but most stuff is
working I think. [Even Buffalo shipped a 2.6.16 kernel, and that
was last September ...]
Good news though is that Tzachi Perelstein from Marvell has released
patches for basic support of the MV88F5281 (Orion-2) in current
upstream kernels, and support for the MV88F5182 (Orion-NAS) is next
in the pipeline.
I see that the 88F5281 has a VFP unit; does the 88F5182 have one
too? I guess not if the chip targets NAS rather than media
processing. And who named these chips anyway? .... Dyslexics will
be lost :)
Hope this doesn't sound too negative; it's great to see you moving
to 2.6. And you asked for comments .... :)
