These values can be used to sign a U-Boot image for use when loading an image through the Serial Download Protocol (SDP). Note that the address of 0x910000 is usable with the stock configuration of imx_usb_loader on i.MX6 and i.MX7 SOCs: https://github.com/boundarydevices/imx_usb_loader/blob/master/mx6_usb_work.conf#L3 Refer to the section on imx_usb_loader in this post for more details: https://boundarydevices.com/high-assurance-boot-hab-dummies/ Signed-off-by: Eric Nelson <eric@nelint.com>
