u-boot with TPM

Hi, I need a u-boot package for Raspberry Pi 4 with TPM / Soft SPI configuration as shown here: https://github.com/joholl/rpi4-uboot-tpm/blob/ad31306ce2f2d52f0572385bfc8bac... Otherwise, tpm2_pcrread shows blank PCR values. Would it be possible to enable this for the current u-boot-rpi4 package, or can we package a separate package with a name such as "u- boot-rpi4-tpm" which has this specific configuration? I have a fork here which already does it: https://build.opensuse.org/package/show/home:jonaski:vendanor/u-boot And how do I solve this? "unresolvable: nothing provides %prjconf_multibuild_selection" without removing "BuildRequires: %prjconf_multibuild_selection". Jonas
