RK3588 optee question

[Alexander Shiyan]

Hello, Sascha.

With CONFIG_SCRATCH_SIZE=0x100000 compiles fine.

Now about the current errors, one build is used for two images for
RK3568 and RK3588.

RK3568, Rockchip BL31, tee.bin from OPTEE_OS:
arm-scmi firmware:scmi.of: SCMI Protocol v2.0 'rockchip:' Firmware version 0x0
optee: smc_abi: probing for conduit method.
optee: smc_abi: revision 4.10 (5c827bf3bc358e9a)
psci psci.of: detected version 1.1

RK3588, open source TF-A, tee.bin from OPTEE_OS:
arm-scmi firmware:scmi.of: SCMI Protocol v2.0 'rockchip:' Firmware version 0x0
optee: smc_abi: probing for conduit method.
WARNING: optee: smc_abi: api uid mismatch
ERROR: optee firmware:optee.of: probe failed: Invalid argument

Switching to a configuration using Rockchip BL31 with the TEE/OPTEE options
currently enabled results in a constant restart of DDR init code, meaning the
code never reaches BL31...

What else can I watch?

Thanks!
