Yes, but that is not the issue. The issue is that the section
extern has no place in a driver, this is precisely what asm/sections.h is
for. Only microblaze and sh define it there today, and there is already
inconsistency. Having the others define it for themselves and agreeing on
a type would permit us to kill it off from the driver.
