[PATCH v2 0/5] edison: Support for writing an xFSTK image
At present it is painful to put Edison in a hardware lab because it has two separate recovery modes. When the board has a functioning U-Boot, DFU can be used. Otherwise an xFSTK image must be used.
This series converts Andy's script to a binman description so that U-Boot can produce an xFSTK image directly.
With this, I can put an Edison in my lab fairly easily.
The series is available at u-boot-dm/edison-working and is based on the reset binman series for sunxi.

Changes in v2: - Minor indenting change in ObtainContents() - Rename MBR to OSIP - Drop git hash from U-Boot version string
Simon Glass (5): x86: Use multiple images binman: Show an error when a file is missing binman: Support adding a U-Boot environment x86: edison: Generate an image suitable for xFSTK x86: edison: Add documentation for using am xFSTK image

We already use binman's 'multiple-images' feature with Chrome OS and we want to use it for Edison. There is no real down-side.
Adjust x86 to always use multiple-images.

The recent support for missing external binaries does not show an error message when a file is genuinely missing (i.e. it is missing but not marked as 'external'). This means that when -m is passed to binman, it will never report a missing file.
Fix this and add a test.

In some cases it is useful to include a U-Boot environment region in an image. This allows the board to start up with an environment ready to go.
Add a new entry type for this. The input is a text file containing the environment entries, one per line, in the format:

It is useful to be able to flash Edison directly without relying on the installed U-Boot being functional.
Add a binman image for this. It includes a 'OSIP' header (which happens to look like an MBR / (Master-Boot Record), U-Boot binary and an environment.
I am not able to find a specification for OSIP.
