Re: RK3588 optee question

Hello Sascha.

After enabling CONFIG_ARCH_ROCKCHIP_ATF_PASS_FDT=y the following build
errors occur:

So, to avoid this, can we define default for CONFIG_SCRATCH_SIZE as
CONFIG_ARCH_ROCKCHIP_ATF_FDT_SIZE if this option is used?

Finally, at least for RK3568 (cannot test RK3588 right now), the init
errors are gone:
...
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
...

The rksecure now works like this:
barebox@Diasom DS-RK3568-SOM-EVB:/ rksecure -i
NOTICE: optee: optee: No supplicant or RPC handler for command 0x0
ERROR: rk-secure: TA 5cfa57f6-1a4c-407f-94a7-a56c8c47019d: error 0xffff0009
