Where is this defined? Or should be? Not top important issue now, as I
can continue with ubldr.bin for some time, but I still would like to
check it.

Private mail will follow.

I just found the reason 'make buildkernel' does not work for me - my
kernel config file is basically stock A20, and cc barfs with

error: unknown target CPU 'armv7a'

which is from /sys/arm/allwinner/a20/std.a20 - how can I find which
target CPU is supported by my cc? Maybe I need to adjust my build
script, but it is basically just

setenv SRCROOT /data/src/11
setenv TARGET arm
setenv KERNCONF ORANGEPI
setenv MAKEOBJDIRPREFIX /mnt/workdir/arm/obj
cd ${SRCROOT}
make buildworld
make buildkernel

(with some -DWITHOUT_YYY as make flags).
