The following patch series reworks the board support code for PowerPC 44x
platforms. It eliminates a number of redundant <board>.c files and add a
ppc44x_simple.c file that has an explicit list of boards that are supported
by it. This is the same mechanism that Grant Likely has used for MPC 5200
boards.
It also adds some more explicit support for Glacier and Yosemite boards, as
those boards were using a board level compatible property in their DTS files
that was a bit confusing.
Review would be appreciated. Tested on Sequoia, and I plan on testing on as
many boards as I can before committing to my tree.

Sorry if I miss anything, but
what happens if I build an uImage just for Rainier (not enabling other
platforms in the kernel config) and then start it on Canyonlands for
example?
They both use PowerPC_44x_simple stuff and looks like now we claim that
all these "simple" boards are compatible. So, board check always passes,
although Canyonlands support is actually disabled (CONFIG_460EX = n;
CONFIG_PPC4xx_PCI_EXPRESS = n). It's not critical, but I just thought we
might also remove the platform-specific options from
arch/powerpc/platforms/44x/Kconfig for these boards at all. Just enable
all board-specific stuff under "config PPC44x_SIMPLE".
Otherwise we probably should have a configurable char *board[] array.
Thanks,
Valentine.
