Hi Ilias,

...

Add MM communication support using FF-A transport

This feature allows accessing MM partitions services through EFI MM communication protocol. MM partitions such as StandAlonneMM or smm-gateway secure partitions which reside in secure world. ...

Changelog:

v19:

Tom:

• use CONFIG_FFA_SHARED_MM_BUF_* in place of macros

v18:

Ilias, Tom:

• drop the use of configs for the shared MM buffer, put back #ifdefs instead
• add test information to the commit log

Thanks for the quick rework. I like the fact you have the SMC as a fallback to FF-A in case it's not discovered. Once and if we get dynamic buffer allocation for the NS-world we can easily switch this to an automatically scanable feature again.

Tom, I am fine with the series now. I've reviewed the relevant EFI and asm bits, feel free to pull it in if the rest of the people are happy.
