U-Boot should be compiled with stm32mp15_trusted_defconfig which is
supported since tag v2019.07-rc1 with commit [1].

The creation of the U-Boot binary with stm32 header is done at U-Boot
compilation step, it is no more required to call the extra command.

The platform port documents are not very standardised right now and
they don't integrate properly into the document tree so:

1) Make sure each port has a proper name and title (incl. owner)
2) Correct use of headings, subheadings, etc in each port
3) Resolve any naming conflicts between documents

Since STM32MP1 platform supports different boards, it is necessary
to build for a particular board. With the current instructions, the
user has to modify the DTB_FILE_NAME variable in platform.mk for
building for a particular board, but this can be avoided by passing
the appropriate board DTB name via DTB_FILE_NAME make variable.
Hence document the same in platform doc.

Support booting OP-TEE as BL32 boot stage and secure runtime
service.

OP-TEE executes in internal RAM and uses a secure DDR area to store
the pager pagestore. Memory mapping and TZC are configured accordingly
prior OP-TEE boot. OP-TEE image is expected in OP-TEE v2 format where
a header file describes the effective boot images. This change
post processes header file content to get OP-TEE load addresses
and set OP-TEE boot arguments.
