Simon Glass 31eca69727 x86: ifdtool: Add support for early microcode access 
Some Intel CPUs use an 'FSP' binary blob which provides an inflexible
means of starting up the CPU. One result is that microcode updates can only
be done before RAM is available and therefore parsing of the device tree
is impracticle.

Worse, the addess of the microcode update must be stored in ROM since a
pointer to its start address and size is passed to the 'FSP' blob. It is
not possible to perform any calculations to obtain the address and size.

To work around this, ifdtool is enhanced to work out the address and size of
the first microcode update it finds in the supplied device tree. It then
writes these into the correct place in the ROM. U-Boot can then start up
the FSP correctly.
