Merge patch series "pxe: Precursor series for supporting read_all() in extlinux / PXE"

Browse Source 
Simon Glass <sjg@chromium.org> says:

This series includes some patches related to allowing read_all() to be
used with the extlinux / PXE bootmeths.

These patches were split out from the stb4 series, since it will need to
have additional patches for LWIP, to avoid breaking PXE booting when
LWIP is used.
