Enable config 'm' for the QCOMTEE driver to facilitate communication with the Qualcomm Trusted Execution Environment (QTEE) on Qualcomm platforms.
I can do it forever, but next time I will just NAK.
Which platforms need this? Which platforms use this?
Looks like I misunderstood your comment on the last patch regarding Qualcomm platform support for this driver as more of a generic question instead of being a hard request to update the commit message. https://lore.kernel.org/all/f20833a4-1571-41f8-875a-d27086be3090@oss.qualcom...
I will take care of this now, however I am still a bit confused regarding how many platforms should I explicitly list out in the commit message. I took reference of these below patches merged earlier in the defconfig for enabling the QCE crypto block driver, Qualcomm Watchdog driver and Qualcomm RNG driver. And I did not see them listing out any specific Qualcomm platforms which need/use these drivers. I understand that this is because the drivers provide generic functionality applicable on all Qualcomm SoCs. https://lore.kernel.org/all/20220921045602.1462007-5-bhupesh.sharma@linaro.o... https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i... https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
Similarly, all Qualcomm SoCs have ARM TrustZone support with a QTEE firmware OS running. The version of the firmware might differ, but it is always there, and so the QCOMTEE driver is applicable to all Qualcomm SoCs just like the Watchdog or RNG driver.
Please do let me know however if we must provide an explicit list of applicable Qualcomm platforms which benefit from this driver.
Thank you, Harshal
