For everybody interested please find in attachment my OMAP1
realtime patch.

It's tested on OSK and boots with both, MPU and 32KHz timer
and plays mp3 via NFS. It's against recent OMAP 2.6.20 git
tree and should be applied on top of patch-2.6.20-rt2 [1].
Note that with our OMAP git, patch-2.6.20-rt2 will not apply
cleanly due to differences between mainline and our git.
Ignore the resulting patch-2.6.20-rt2 rejects, using e.g.
quilt you have to use push -f to force apply.

Order to use:

1) OMAP 2.6.20 git [2]

2) patch-2.6.20-rt2 [1]

(The -rtX patches are frequently updated. > -rt2 patches
should work as well unless major changes)

3) patch-2.6.20-rt2-omap1 in attachment

For more info see [3].

Enjoy,

Dirk
