Greetings,
Corcerning Cirrus patches, they are reserved for their evaluation board.
You will need a login/password to access them.
How I know that cirrus released a "2.6.8.1" patch some times ago.
Back to 2.6 !!! I posted (here) a similar question in march.
I don't remember offcial anwsers from Technologic Systems, but at this
time it was not stable enough and in its very early development stage.
But they worked on it.
It decided to make a (long long) try. Subscribed to linux-cirrus mailing
list :)
With help of few people I booted my TS-7200 with 2.6.11.3-ep93xx. Few
times later I did a terrible mistake in the flash driver, and I crashed
my board. It was also the last days of BitKeeper, and 2 or 3 before git.
I didn't reworked on kernel since this time.
I'm for basing our "linux-2.6.12-ep93xx-ts7200" patch from Michael
Burian (and
co) work and not from cirrus stuff.
Easy to say, but that's not so complicated, the m.burian patch do the
hard stuff
for you (complicated ethernet driver, serial console).
For my TS-7200 experience, it is very similar to EBD9301 (or EBD9302) :
- add a mach-ts7200.c inside arch/arm/mach-ep93xx
- hack some Kconfig files
- I remember that 1 or 2 files were missing on my rootdisk /dev. I was
working
with an arm testing debian
Loved the "Timer and CPU usage LEDs" option :)
Back to present, I don't have time right now for working on the kernel,
that require some
free time and skills ! However, there are nice guys on this group and in the
linux-cirrus ml for helping you.
Good luck !
