I hoped to have missed some mails and that people were testing pandabard
support with full support but given what I see, the ethernet support is
not there yet. This thread is about removing the non-DT boot. I see some
contradiction here. Please, look again at what Thomas said in the IGEP thread:
breaking existing support is bad and removing non-DT boot for panda with
not-working ethernet would exactly to that.
Yeah, I'm aware that some extra patches are being developped like the
omap clocks one: https://patchwork.kernel.org/patch/2541331/ but they
don't seem to be in -next. So, again, please, wait that all needed bits
are merged mainline before killing non-DT support (or provide 'mixed'
support like what is/was done on kirkwood)
Thanks,
Arnaud
