Ok, I have a better fix for this one, which won't mess up the kernel build:
Assuming that the SDECFG_ARM_BOARDDEF='versatile' is the proper one to
build the Raspberry Pi Kernel,
that should be put back into target/rasperrypi/config.in :

(at least the kernel headers don't fail with this)
And then u-boot.conf should be fixed up for the exception of the
defconfig, I noticed a similar fix for the avr32, so this would be more
consistent with the existing conventions:

Hi Rene,
looks like I spoke too soon, I did a "Cleanup -build" and tried a
full re-build, and it's failing in the kernel headers now.
The actual problem is that the defconfig settings are also used in the
kernel builds, but the defconfig naming is different between the
kernel & uboot.
This may also be worsened by the fact that the kernel for the Pi is
pinned at 3.19 (2012 vintage), with a lot of Pi specific patches, but
the u-boot version is from Nov 2016. so the list of defconfig files
may have changed a lot since 2012. The newer kernels now have a lot
of built in support for the Raspberry Pi, and the defconfigs may now
be a better match.
That being said, I don't want to jump ahead of things and update the
kernel just now, since I am at the point of just trying to get through
the build process, and don't want to unknowingly add any run-time
surprises, I will try some further changes later today, to revert
the SDECFG_ARM_BOARDDEF='versatile' to keep the kernel happy, but then
override it with a value that makes u-boot happy, during the u-boot
build.
Once I have something running, I will consider updating the kernel.

One of the Pi failures was in u-boot, the T2 configuration was
asking for the 'versatile' defconfig, but that does not exist in the
u-boot source tree. But they do have some defconfigs to cover
various models of the raspberry pi (rpi rpi_2 rpi_3)
I got u-boot to build by changing the SDECFG_ARM_BOARDDEF to be
'rpi', and also adding that option to the
architecture/arm/config.in file.
I am not sure if this is the proper fix, since I don't know what
else SDECFG_ARM_BOARDDEF is used for. if it's only used for u-boot,
then this will work, if other packages use SDECFG_ARM_BOARDDE, then
the 'rpi' setting may not work.
I would like a build that would run on all versions of the Pi, so I
am using 'rpi'instead of 'rpi_3', but I am not sure if this will
work yet.
