I see that defining ARCH_MULTIPLATFORM selects AUTO_ZRELADDR
Is that what is supposed to make Makefile.boot not required?

If I remove Makefile.boot altogether, 'make uImage' fails with

  Kernel: arch/arm/boot/Image is ready
  Kernel: arch/arm/boot/Image is ready
  Kernel: arch/arm/boot/zImage is ready
  Kernel: arch/arm/boot/Image is ready
  Kernel: arch/arm/boot/zImage is ready
multiple (or no) load addresses: 
This is incompatible with uImages
Specify LOADADDR on the commandline to build an uImage
make[1]: *** [arch/arm/boot/uImage] Error 1
make: *** [uImage] Error 2


On an unrelated topic, someone wrote
select CPU_USE_DOMAINS if MMU
in my platform Kconfig. But looking at arm/mm/Kconfig,
it looks like it is not set for other V7 platforms.
Is this an obsolete feature that I should remove?
