does imx8qm support using CAAM in TEE

Hi nxp engineers,

For imx8qm serials, does it support CAAM in OPTEE

as I checked, CFG_NXP_CAAM was force set as false...

else ifneq (,$(filter $(PLATFORM_FLAVOR),$(mx8qm-flavorlist)))
$(call force,CFG_MX8QM,y)
$(call force,CFG_ARM64_core,y)
$(call force,CFG_IMX_SNVS,n)
CFG_IMX_LPUART = y
CFG_DRAM_BASE = 0x80000000
CFG_TEE_CORE_NB_CORE = 6
$(call force,CFG_NXP_CAAM,n)
$(call force,CFG_IMX_OCOTP,n)

thanks.

By default,Cryptographic algorithms are not accelerated by CAAM on OPTEE. How to enable it you can refer to this thread:
