This series adds a few improvements to the image signing feature to make it easier to use on the Beaglebone Black.
- Add a DEV_TREE_BIN option to make it easier to include the correct FDT (with embedded public keys) into the U-Boot image - Enable cache for more TI boards (to speed things up) - Increase malloc size - Enable CONFIG_OF_CONTROL, FIT and secure boot on am33xx/omap (RFC only, not sure we want this, although we could create a separate config for it)
I also have a change to adjust mkimage to automatically make space in the FDT when adding hashes and signatures. Included here is the ENOSPC patch, but the fit_image.c patch will wait until the dumpimage tool is merged, since I am changing the same code.
With this, secure boot was tested successfully on Beaglebone Black.
Simon Glass (8): am33xx/omap: Allow cache enable for all Sitara/OMAP hash: Export functions to find and show hash fdt: Add DEV_TREE_BIN option to specify a device tree binary file fdt: Update functions which write to an FDT to return -ENOSPC arm: ti: Increase malloc size to 16MB for armv7 boards RFC: am33xx/omap: Enable CONFIG_OF_CONTROL RFC: am33xx/omap: Enable FIT support RFC: am33xx/omap: Enable secure boot with CONFIG_FIT_SIGNATURE
