With CONFIG_ARCH_STM32 making it into arch/arm64, a couple of format
strings no longer work, since they rely on size_t being compatible
with %x, or they print an 'int' using %z:

Fix up all three instances to work across architectures, and enable
compile testing for this driver to ensure it builds everywhere.

I also have it for the stm32mp2 :)

Please find a remark below , with or without that

What about cast the RSC_TBL_SIZE define instead to ensure to be independent from
the arch and to match with the use of RSC_TBL_SIZE?

#define RSC_TBL_SIZE		((size_t)1024)

Thanks,
Arnaud

I have no objection to that, but I don't see it doing anything good either,
as this is a constant value that will always work.

It was just to avoid to have the constant used with different types in the code
But that's nitpicking, let's keep your proposal.

The kernel robot shot me for my STM32MP25  PR due to this issue. Do I 
have to resend something ?
