Hi Lucy,

Here are the NXP LPC288x patch against linux-2.6.21 kernel and the
vendor/NXP directory for uClinux.
The same resources would also be found in the LPC2400_uClinux Yahoo
group as well as a getting started document.

Couple of comments:
1. Your diff/patches are reversed. Please generate them using something
like "diff -Naurp <old> <new>". Note that <old> is first, <new>
second :-)
2. It is not a good idea to manually add entries to the arm arch machine
table. Go to the ARM linux web site http://www.arm.linux.org.uk/
and in the developer section you can add machine entries.
(Code doesn't need to be in the kernel yet for it).
3. Use standard names where possible, for example
arch/arm/mach-lpc28xx/Kconfig-features should just be Kconfig
4. not strictly necessary but it is nice to consistently put
GPL type license text at top of new source files (some in the
kernel patch have it, some dont').
5. In a few spots looks like debug and trace code still in.
6. Try to avoid white space changes in amongst other changes.
I have applied the vendors support to uClinux-dist. I have applied
quite a few of the lpc kernel changes - not all though. The arch
specific parts are ok.
Have a look what ends up in the next uClinux-dist patch (in the
next couple of days) and we can sort out the remaining bits.
Note that to push this up to mainline would require some more
cleanup work too. But some testing time in the uClinux-dist
seems like a good start.
Thanks
Greg
