An easy approach would be to list both ARM_SINGLE_ARMV7M and
EFM32 in the UNCOMPRESS_INCLUDE option initially, and then
follow-up with a patch that converts the three other platforms
(efm32, stm32 and lpc18xx) to ARM_SINGLE_ARMV7M and also
change the UNCOMPRESS_INCLUDE statement.

Note that I've already added both stm32 and lpc18xx to the
UNCOMPRESS_INCLUDE list in the next/soc branch.

I'm fine with that, too. If Shawn thinks the patches are ok, you can
just send all patches you want me to apply in arm-soc based on
the appropriate branches (next/soc, next/dt and next/defconfig, I
presume), and I'll apply them this time. In the future, you should
send all patches to Shawn though.
