<wens> lvrp16: for rk3399, likely yes; for rk3328, the non-secure efuse is empty
<wens> lvrp16: u-boot already has support for the rk3399 efuses, and enabling a few Kconfig options will make it generate stable MAC addresses
<lvrp16> wens: cool thanks. just wondering if there were any soc ids like meson's chip id
<wens> lvrp16: rk3399 has 16 bytes cpu id
<lvrp16> wens: gotcha so they have no consistent mechanism across socs?
<wens> lvrp16: nope (unless there's something in trusted firmware I don't know about)

<mmind00> dvergatal: up to 3.7.0 you just need to place the optee .elf as "tee.elf" into your uboot build directory ... see https://gitlab.denx.de/u-boot/u-boot/-/blob/master/arch/arm/mach-rockchip/make_fit_atf.py#L212
<mmind00> dvergatal: if that tee.elf is present it will be included into the u-boot.itb
<mmind00> dvergatal: of course you need to make sure that you built atf with the correct params (added option: SPD=opteed)
<mmind00> with 3.8.0 optee changed their build process and nobody has adapted the u-boot side yet
<dvergatal> mmind00: ech but optee-3.9.0 has the support for rk3399
<mmind00> dvergatal: the rk3399 patches should be backportable ... for newer versions you'd need to investigate how to adapt to the new optee build
<dvergatal> ach oki so just copy tee.bin from optee and bl31.elf from atf
<dvergatal> and built uboot
<dvergatal> mmind00: now i know why rockchip has to radisys (our client) that they have optee support only up to 3.6.0
<dvergatal> mmind00: now i know why rockchip has told to radisys (our client) that they have optee support only up to 3.6.0
<dvergatal> sorry for typo
