Arm FF-A updates for v6.15
This update primarily focuses on FF-A framework notification support
along with other improvements, including UUID handling enhancements
and various fixes.
1. FF-A framework notification upport
- Adds support for multiple UUIDs per partition to register individual
SRI callbacks.
- Handles Rx buffer full framework notifications and provides a general
interface for future extensions.
2. Improved multiple UUID/services per-partition handling
- Adds support for UUID passing in FFA_MSG_SEND2, improving multiple
UUID/service support in the driver.
- Introduces a helper function to check whether a partition can
receive REQUEST2 messages.
3. Partition handling generic improvements
- Implements device unregistration for better partition cleanup.
- Improves handling of the host partition presence in partition info.
4. FF-A version updates
- Upgrades the driver version to FF-A v1.2.
- Rejects major versions higher than the driver version as incompatible.
5. Big-Endian support fixes
- Fixes big-endian issues in:
__ffa_partition_info_regs_get()
__ffa_partition_info_get()
- Big-endian support is still incomplete, and only these changes can
be verified without additional application/testing updates at the
moment. We can discover all the partitions correctly with big-endian
kernel now.
6. Miscellaneous fixes
- Fixes function prototype misalignments in: sync_send_receive{,2}
- Adds explicit type casting for return values from: FFA_VERSION
and NOTIFICATION_INFO_GET
- Corrects vCPU list parsing in ffa_notification_info_get().
7. UUID management in the driver and DMA mask updates
- Replaces UUID buffer with the standard UUID format in ffa_partition_info
structure.
- Fixes a typo in some FF-A bus macros.
- Sets dma_mask for FF-A devices.
In short, this update enhances notification handling, UUID support, and
overall robustness of the FF-A driver while addressing multiple fixes
and cleanups.
