f61831ee61 ARM: mach-shmobile: ap4evb, mackerel: fixup scif initialisation for zboot
* Set receive enable and transmit enable bits of SCASCR0 (E6C400089).
  Values previously written to this register was bogus.

  Curiously earlyprintk works with the previous code.

* Remove duplicate initialisation of GPIO port 152, SCIFA0_TXD (0xE6053098).
  This should have no effect other than to very slightly reduce the amount of
  code.

3d09fbcd26 ARM: 6514/1: mach-shmobile: Add zboot support for SuperH Mobile ARM
When CONFIG_ZBOOT_ROM is selected, the resulting zImage file will be small
boot loader and may be burned to rom or flash.

This is the board-specific portion of this patch-set.
