Commit Message

Allred, Daniel April 11, 2016, 11:37 p.m. UTC 
Modifies the config.mk to build secure images when building
the SPL for secure devices.

Depending on the boot media, different images are needed
for secure devices. The build generates u-boot*_HS_* files
as appropriate for the different boot modes. The same u-boot
binary file is processed slightly differently to produce a
different boot image, depending on whether the user wants to
boot off SPI, QSPI or other boot media.

Refer to README.ti-secure for more information.
