RK3588 optee question

[Alexander Shiyan]

Hello.

Yes, kernel loading stops immediately after loading the scmi driver.

I think that everything is described correctly, because the image with a working
configuration (Rockchip BL31) and a non-working one (TF-A) differ only
in the binary itself.

Here is a RK3588 output, and for the RK3568 the output is quite similar:
[root at diasom-evb ~]# dmesg | grep tee
[    0.000000] OF: reserved mem:
0x0000000030000000..0x0000000031bfffff (28672 KiB) nomap non-reusable
optee_core
[    0.000000] OF: reserved mem:
0x0000000031c00000..0x0000000031ffffff (4096 KiB) map non-reusable
optee_shm

Thanks!
