This will probably break other platforms if
CONFIG_PPC_EARLY_DEBUG_USBGECKO
is set. In general, we try hard to make it possible to build generic
kernels for multiple systems, so it would be better to also add a
runtime check here.
No Arnd. The whole point of EARLY_DEBUG is that it is -known- to break
other platforms :-) So that we can use it before we even get to probe
anything.
I am still tempted, one day, to change the kernel early init to
setup a
stack in .bss and go straight to C to do that sort of stuff by parsing
the flat DT, this could be done using pretty much completely generic
code :-) But not right now.
No Ben. The whole point of EARLY_DEBUG is that it _always works_,
because
it is such trivial code. Don't break that please, or we'll be forced to
add a "REALLY_EARLY_DEBUG" instead :-)
