This adds support for specifying FDT overlays in an extlinux/pxelinux configuration file.
Without this, there is no simple way to apply overlays when the kernel and fdt is loaded by the pxe command.
This change adds the 'fdtoverlays' keyword for a label, supporting multiple overlay files to be applied on top of the fdt specified in the 'fdt' or 'devicetree' keyword.
Example: label linux
kernel /Image devicetree /soc-board.dtbThis should be "fdt /soc-board.dtb",
Indeed, thx
fdtoverlays /soc-board-function.dtbo append console=ttyS0,115200 root=/dev/mmcblk0p2 rootwaitThis code makes usage of a new variable called fdtoverlay_addr_r used to load the overlay files without overwritting anything important.

Since I'll almost certainly forget when applying, can I get a v3 with the change? Thanks!
