Linaro OP-TEE Contribution, LOC, monthly meeting May 27

[Jens Wiklander]

Hi,

Tomorrow, Tuesday, it's time for another LOC monthly meeting. For time
and connection details, see the calendar at
https://www.trustedfirmware.org/meetings/

OP-TEE version 4.6.0 was released on April 25.

Amir posted a v4 [1] of the QTEE driver. Sumit and I have spent quite
a bit of time reviewing this, but it would be welcome with comments
from others, too. For instance, for "tee: add
TEE_IOCTL_PARAM_ATTR_TYPE_UBUF" which adds yet another type of memory
reference.

optee_ftpm Issue "Warning in _plat__GetUnique()" [2], digging in this
reveals further issues.

[2] https://github.com/OP-TEE/optee_ftpm/issues/15

Are there any other topics?

Thanks,
Jens
