Adds a centralized config_secure.mk in omap-common for OMAP-style TI secure devices to use for boot image generation
Depending on the boot media, different images are needed for secure devices. These commands generates u-boot*_HS_* files that need to be used to boot secure devices.
Please refer to README.ti-secure for more information.
