[PATCH 0/5] edison: Fix mainline boot and convert the image to binman

[Simon Glass]

Mainline U-Boot does not boot on the Intel Edison. The mask ROM enters
the OS image 0x1000 above its load address, so U-Boot needs 4KB of zero
padding ahead of it. That padding used to come from an alignment rule in
board/intel/edison/config.mk, but the Kbuild-6.1 bump stopped that input
being built, so u-boot.bin now starts with code at offset 0 and the ROM
jumps into the middle of it.

This series moves the image build into binman: a new intel-osip entry
generates the OSIP header (with the GPT-protective MBR the mask ROM
needs) and a fill provides the 4KB gap, replacing the config.mk hack and
restoring the boot. It also widens the DFU auto-probe window so an
automated flash has time to start, adds the board to the sjg-lab CI and
rewrites the documentation to separate a normal DFU update from xFSTK
recovery.

Tested on real hardware: a bricked board recovers via xFSTK, takes a
fresh U-Boot over DFU and boots the result.
