I have ported i.MXRT10xx family to uboot while Jesse the i.MXRT11xx
family and then we ported the initial support to Linux too.

I have checked the S32K family but it doesn't have a sdram bus so even
if on some component u-boot can run then I don't know if you could
run Linux or other OSes :-/

While S32G2/3 instead support DDR3L/LPDDR4 but they have a lot of
cortex-M7 and a lot of cortex-A53. This is a completely different
architecture.

S32R same as S32G.

S32Z2 and S32E2 instead are based on cortex-R52+M33 and they both
support LPDDR4 memory.

It depends on your goal.
