PMERRLOC resource size was set to 0x100, which resulted in HSMC_ERRLOCx
register being truncated to offset x = 21, causing error correction to
fail if more than 22 bit errors and if 24 or 32 bit error correction
was supported.

Even if it's a fix, as we have this bug for a long time and that we are already at rc5 of the stabilization phase, I take it in at91-dt branch for 5.18 and not in another "fixes" batch.

Best regards,
