Etienne Carriere 6959d628d4 boot/arm-trusted-firmware: add support for using OP-TEE as BL32
This change allows one to build trusted firmware (TF-A) with OP-TEE as
BL32 secure payload.

When BR2_TARGET_ARM_TRUSTED_FIRMWARE_BL32_DEFAULT is enabled TF-A
builds a BL32 stage according the TF-A configuration directive.  If
these specify no BL32 stage then TF-A will build without BL32
support. This is the default configuration and reflects TF-A legacy
integration in BR.

When BR2_TARGET_ARM_TRUSTED_FIRMWARE_BL32_OPTEE is enabled TF-A builds
with support for the OP-TEE OS as BL32.

README

Buildroot is a simple, efficient and easy-to-use tool to generate embedded
Linux systems through cross-compilation.

The documentation can be found in docs/manual. You can generate a text
document with 'make manual-text' and read output/docs/manual/manual.text.
Online documentation can be found at http://buildroot.org/docs.html

To build and use the buildroot stuff, do the following:

1) run 'make menuconfig'
2) select the target architecture and the packages you wish to compile
3) run 'make'
4) wait while it compiles
5) find the kernel, bootloader, root filesystem, etc. in output/images

You do not need to be root to build or run buildroot.  Have fun!

Buildroot comes with a basic configuration for a number of boards. Run
'make list-defconfigs' to view the list of provided configurations.

Please feed suggestions, bug reports, insults, and bribes back to the
buildroot mailing list: buildroot@buildroot.org
You can also find us on #buildroot on Freenode IRC.
