# This is responsible for extracting the DXE section from the ROM,
# extracting each of the images from it, and setting the sizes for
# the different firmware images.
#
# For space reasons the DXE is put in the recovery FV at 0x2C00000
# and the kernel/initrd are put in a separate volume at 0x3500000.
#
# To upload the entire ROM (including ME and PEI):
# ( echo u0 4000000 ; pv build/s2600wf/linuxboot.vol ) > /dev/ttyACM0
#
# To upload just kernel or DXE:
# ( echo u3500000 400000 ; pv build/s2600wf/linux.vol ) > /dev/ttyACM0
# ( echo u2c00000 400000 ; pv build/s2600wf/dxe.vol ) > /dev/ttyACM0
