Or is it that function-sections is not working as expected with the older
toolchains? The above error is with the nand_command function in the
nand_base.c which should not be getting linked at all -- the nand_command
function in the nand_spl_simple.c gets used for the spl build. The
functions in nand_base.c should get discarded, which should take care of
the undefined udelay. I disassembled the u-boot-spl file with my toolchain,
and don't see a udelay getting included at all -- as is expected with the
spl build. Btw, the nand_command function in nand_spl_simple.c is getting
name mangled by the compiler.
