Hi Peter,
Please take a look at the attached. Note that the default kernel variant
is actually a versatile, and you weren't inheriting that. Also, we need
to set the V6_V7 multiplatform option because the current Kconfig logic
will otherwise enable AUTO CPU support, which will force us to have a V5
kernel. So take a look. I'll be online later.
Tested with a cross compiler only, but it built.
Jon.
