[U-Boot] [PATCH 0/8] x86: Support microcode in a single place

As part of the effort to support Atom processors it became apparent the
they can only support microcode updates before RAM is available. In this
early environment the device tree is not available.

This series solves this problem by updating ifdtool to provide very early
microcode access on these platforms.


Simon Glass (8):
  x86: Add a script to process Intel microcode files
  x86: ifdtool: Correct a debug() missing parameter
  x86: ifdtool: Display filename when file errors are reported
  x86: ifdtool: Use a structure for the file/address list
  x86: ifdtool: Add support for early microcode access
  x86: Move microcode updates into a separate directory
  x86: ivybridge: Update the microcode
  x86: Convert microcode format to device-tree-only
