You're right, Andrew -- Rob (CC'd) changed the MMC Kconfig to build this
driver on Sparc. Mainline commit 236cdc7bc71 ("of: make drivers depend
on CONFIG_OF instead of CONFIG_PPC_OF").
Rob also posted a patch to devicetree-discuss@, on top of the one above
("mmc: sdhci-of: fix build on non-powerpc platforms"), to fix up the
Sparc build by ifdef'ing for PPC inside the driver. Grant merged the
first patch but not the second, hence sparc64 allmodconfig is broken
now. The reason Grant didn't merge the second patch may be that Wolfram
objected to #ifdef proliferation inside the driver.
Options, as I see it:
* revert the commit such that MMC_SDHCI_OF once again depends on PPC_OF
* take the second patch as-is
* come up with a less-#ifdeffy second patch
Wolfram, would appreciate your input on what we should do here. Thanks,
