Subject: [PATCH v3 00/13] Add support for using FF-A calls
Date: Fri, 15 Jan 2021 11:43:51 +0530 [thread overview]
Message-ID: <20210115061404.13552-1-sughosh.ganu@linaro.org> (raw)
The following patch series adds support for using the Firmware
Framework(FF-A) as a transport mechanism for requesting services from
the Secure Partition Manager(SPM). This is done through a Pcd which
can be used to enable the FF-A mechanism or to use the earlier used
SVC calls.
The patches have been pushed to my github repository[1]
Changes since V2:
* Added a STATIC storage class specifier for mSpmMajorVer and
mSpmMinorVer variables
* Added a STATIC storage class specifier for mSpmMajorVerFfa and
mSpmMinorVerFfa variables
* Add braces for if/else statements
* Add a check for EFI_NOT_FOUND as a possible return value from
LocateStandaloneMmCorePeCoffData in _ModuleEntryPoint function
* Check for the return value in Arg0 after the Direct Request call to
handle errors returned
* Put a comment to reflect the fact that FFA_INTERRUPT and FFA_SUCCESS
response won't be expected in return to a Direct Request call to get
the memory attributes
* Check for the return value in Arg0 after the Direct Request call to
handle errors returned
* Put a comment to reflect the fact that FFA_INTERRUPT and FFA_SUCCESS
response won't be expected in return to a Direct Request call to set
the memory attributes
