From 883dfd15536e41d2b994099dd478be5a18660960 Mon Sep 17 00:00:00 2001 From: Daniel Allred Date: Thu, 19 May 2016 19:10:46 -0500 Subject: [PATCH] ti: AM43xx: config.mk: Add support for generating secure boot images 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.
