[Abdellatif El Khlifi]

Moving the changelogs in each commit to the changes section.

No code change in v5.

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

Cheers,
Abdellatif
