[PATCH 00/24] ARM: stm32mp: add trusted bootchain (SCMI&FIP) support

[Ahmad Fatoum]

ST calls trusted firmware + SCMI for accessing some secure resources the
trusted boot chain (as opposed to the basic bootchain). This is
independent of cryptographically secured boot. So far, barebox generated
images with a STM32 header prepended, which could be booted after
upstream TF-A. This extends barebox to generate an extra image suitable
for inclusion in A TF-A Firmware Image Package and teaches barebox to
support firmware clocks and resets provided by TF-A over secure monitor
calls. There are no upstream DTs yet with SCMI and intention seems to be
to have boot firmware fix up the nodes. The SCMI changes here have been
tested by taking OpenSTLinux with its downstream TF-A, U-Boot, OP-TEE
and Linux components and just replacing U-Boot with barebox via fiptool
update.

Cheers,
