Hi Alice,

I have a board with IMX95 A1 silicon - with respect to this
documentation should that be considered A0 vs B0? Are there any issues
with A1 that would make the oei/sm/atf/uboot not compatible here?

As far as I can tell the only part of boot firmware that needs
compile-time configuration based on silicon revision is the imx-oei
and I only see special handling for r=A0. If I build with anything
other than r=A0 the OEI does not run for me whereas building with r=A0
the OEI's appear to run fine yet I don't seem to make it to U-Boot
SPL.

Any ideas?

Best Regards,

Tim
