I've applied the series to u-boot/master.  But please note that with the
toolchain links above, MAKEALL doesn't agree that axs101 builds without
error (but doing it with 'make' does) and arcangel4 doesn't build due
to:
arc-linux-ld.bfd: Error: Overflow detected in relocation value;
arc-linux-ld.bfd: Relocation value should be between 16777215 and -16777216 whereas it  2130661664
arc-linux-ld.bfd: Global symbol: "default_serial_console".
arc-linux-ld.bfd:
Relocation type is:R_ARC_S25W_PCREL
FileName:drivers/serial/built-in.o
Section Name:.text
Offset in Section:10
arc-linux-ld.bfd: final link failed: Bad value
make: *** [/home/trini/work/u-boot/u-boot/temp/u-boot] Error 1
