[PATCH v3 00/18] pxe: Refactoring to tidy up and prepare for bootflow

[Simon Glass <sjg@chromium.org>]

This collects together the patches previously sent relating to PXE.

Firstly, it moves the boot code out of common/ and into a new boot/
directory. This helps to collect these related files in one place, as
common/ is quite large.

Secondly, it provides patache so clean up the PXE code and refactor it
into something closer to a module that can be called, teasing apart its
reliance on the command-line interpreter to access filesystems and the
like. Also it now uses function arguments and its own context struct
internally rather than environment variables, which is very hard to
follow. No core functional change is intended.

Changes in v3:
- Rebase to -master

Changes in v2:
- Rebase to -next
- Split out from the bootmethod patches
