These are the TOE regs (CSR0 included), they only exist on RZ/G2L, no?
See just one line above you can see CSR0 registers and comments on the right clearly
mentions "/* Documented for RZ/G2L only */
What I meant was commenting on them as /* RZ/GL2 only */ or some such.
Sorry for not being clear enough.
OK will do CSR0 initialisation as part of this patch instead of patch #10.
TIA!

... as this function returns u32.
I'm even suggesting to call this variable 'csr0'.
