I have been using Yocto Project release Honister with meta-freescale for an i.MX6ul based target very similar to the mx6ul_14x14_evk. u-boot-fslc_2021.07 with SPL builds and works fine.
I am in the process of updating to YP release Kirkstone. However, now with u-boot-fslc_2022.07 building SPL fails with the following messages:

Essentially the two symbols 'reset_cpu' and 'read_fuse' cannot be resolved. The configuration settings CONFIG_SPL_LIBGENERIC_SUPPORT and CONFIG_SPL_LIBCOMMON_SUPPORT are enabled. I am somewhat at a loss what could have changed. Maybe someone from the NXP team involved with u-boot can shed some light on it. Thank you.
