Hi Garrett:

Thanks for the report -- I didn't realise tinderbox was now building all =
kernels, or I would have merged my fix from P4 more quickly.

The patch you've attached isn't quite the right one -- BERI supports =
both FDT and non-FDT kernels, so we shouldn't build the Openfirmware =
headers in the non-FDT case. Instead, I've ifdef'd inclusion of the =
headers. However, as is probably clear from my breaking the non-FDT =
kernel configuration, I have been working only with FDT kernels. :-)

Thanks,

Robert
