[PATCH v2 0/5] scripts: rockchip: fix and cleanup rkimage

[Michael Tretter <m.tretter@pengutronix.de>]

This series prepares the Rockchip tooling for creating and handling
signed images. The patch series for adding code to sign the images will
follow as a second step.

Fix the wrong size when calculating the hash over the image header.
Rename the hashtype field in the header to flags, because there are
other flags in this field, too. Extend the rk-usb-loader to accept
signed images and load signed images to a board via USB.
