String variables created as field variables and save variables are
already handled properly by having their values copied when set. The
same isn't done for normal variables, but needs to be - simply saving

No need to add a check to subtract the number of bits if bits is zero after

same answer for size of 0 and 1, but that's fine.

We have real overruns. We have ~2800 bytes of XSAVE (regisiter) state
mostly from AVX-512, and a 2048 byte MINSIGSTKSZ.

phy_device_create()) and the queued work may be executed prior to the

Hi.
The first patch is to enable UHS-1 Support for Keem Bay EVM.
The second patch is the header file to handle ATF call.
These 2 patches was tested with Keem Bay evaluation module board.
Kindly help to review this patch set.
Thank you.
