From: Daniel Allred Date: Fri, 20 May 2016 00:10:51 +0000 (-0500) Subject: spl: build: ti: add support for secure boot images X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=410f52579498ebe7863c0b88f417eb2d9fb25551;p=u-boot.git spl: build: ti: add support for secure boot images Updates the SPL build so that when CONFIG_TI_SECURE_DEVICE is in use (which it should be when building for secure parts), the TI secure development package is used to create a valid secure boot image. The u-boot SPL build processes is NOT aware of the details of creating the boot image - all of that information is encapsulated in the TI secure development package, which is available from TI. More info can be found in README.ti-secure Right now, two image types are generated, MLO and X-LOADER. The types are important, as certain boot modes implemented by the device's ROM boot loader require one or the other (they are not equivalent). The output filenames are u-boot-spl_HS_MLO and u-boot-spl_HS_X-LOADER. The u-boot-spl_HS_MLO image is also copied to a file named MLO, which is the name that the device ROM bootloader requires for loading from the FAT partition of an SD card (same as on non-secure devices).
