This series adds support to enable/disable/lock the jtag interface
from u-boot. This becomes handy if secure boot is used but debugging
should be poissible for non-productions builds.

The series also adds support to get/set the multiboot register in order
to ensure a freash bootimage search after soft reset.

  zynq: Add get function for multi boot address register
  zynq: Add function to enable JTAG
  zynq: Add function to lock JTAG enable bits
