So let us keep the SMCCC transportspecific routines abstracted.It is kept simple for now. Once we add another transport, we can developbetter abstraction.Link: https://lore.kernel.org/r/20210521151033.181846-4-sudeep.holla@arm.comTested-by: Jens Wiklander <jens.wiklander@linaro.org>Reviewed-by: Jens Wiklander <jens.wiklander@linaro.org>Signed-off-by: Sudeep Holla <sudeep.holla@arm.com> List of files: /linux-6.15/drivers/firmware/arm_ffa/Kconfig Fri, 21 May 2021 15:10:31 +0000 Sudeep Holla <sudeep.holla@arm.com> http://172.16.0.5:8080/history/linux-6.15/drivers/firmware/arm_ffa/Kconfig#e7818584 firmware: arm_ffa: Add initial FFA bus support for device enumerationThe Arm FF for Armv8-A specification has concept of endpoints orpartitions. In the Normal world, a partition could be a VM whenthe Virtualization extension is enabled or the kernel itself.In order to handle multiple partitions, we can create a FFA device foreach such partition on a dedicated FFA bus. Similarly, different driversrequiring FFA transport can be registered on the same bus. We can matchthe device and drivers using UUID. This is mostly for the in-kernelusers with FFA drivers.Link: https://lore.kernel.org/r/20210521151033.181846-2-sudeep.holla@arm.comTested-by: Jens Wiklander <jens.wiklander@linaro.org>Signed-off-by: Sudeep Holla <sudeep.holla@arm.com> List of files: /linux-6.15/drivers/firmware/arm_ffa/Kconfig Fri, 21 May 2021 15:10:29 +0000 Sudeep Holla <sudeep.holla@arm.com>
