Changelog of the major changes: ===========================
v5:
* move changelogs in each commit to the changes section
v4: [4]
* add FF-A support README (doc/README.ffa.drv) * improving error handling by mapping the FF-A errors to standard errors and logs * replacing panics with an error log * align sandbox driver and tests with the new FF-A driver interfaces and new way of error handling * use the new FF-A driver interfaces for MM communication * discover MM partitions at runtime * copy FF-A driver private data to EFI runtime section at ExitBootServices() * moving the FF-A driver work to drivers/firmware/arm-ffa * improving features discovery in FFA_FEATURES * add remove/bind functions to the FF-A core device * improve how the driver behaves when bus discovery is done more than once * move clearing x0-x17 registers code into a new macro like done in the linux kernel * enable EFI MM communication for the Corstone1000 platform
v3: [3]
* port x0-x17 registers support from linux kernel as defined by SMCCCv1.2 * align the interfaces of the u-boot FF-A driver with those in the linux FF-A driver * remove the FF-A helper layer * make the u-boot FF-A driver independent from EFI * provide an optional config that enables copying the driver data to EFI runtime section at ExitBootServices service * use 64-bit version of FFA_RXTX_MAP, FFA_MSG_SEND_DIRECT_{REQ, RESP} * update armffa command with the new driver interfaces
v2 [2]:
* make FF-A bus discoverable using device_{bind, probe} APIs * remove device tree support
v1 [1]:
* introduce FF-A bus driver with device tree support * introduce armffa command * introduce FF-A Sandbox driver * add FF-A Sandbox test cases * introduce FF-A MM communication
