src/sys/arch/arm/sunxi: sunxi_debe.c
Log Message:
sunxi_debe_set_videomode(): As byte-swapped framebuffer is now handled by
FDT override, do not configure FB to little-endian format for __ARMEB__.
XXX
This function is not actually called at the moment. IIRC, it worked in
the pre-FDT era. Something went wrong since then...
