I still stumbled upon these linker errors when building for my OMAP3
board, using the current linux-omap master branch. I inadvertently had
CONFIG_ARCH_OMAP4=y (leftover from my starting point,
omap2plus_defconfig), but didn't have any of the boards with
omap_phy_internal.o selected (OMAP_4430SDP, OMAP4_PANDA, PCM049, PCM049,
OMAP3517EVM). Maybe this isn't a concern anyway, since anybody building
with CONFIG_ARCH_OMAP4 will presumably also be building one of those
boards? I don't know if it is our goal to build successfully with every
wacky CONFIG_ combination, but I thought I would report it here just in
case.
