(as highlighted in previous review of this patch):
https://lore.kernel.org/linux-arm-kernel/20230728102905.267131-1-varshini.rajendran@microchip.com/T/#m2dac0ce9e1991c3d714785062a76ccdce11a02a6

I want RAM size in Bytes.

Sorry but NACK.

Best regards,

Could you keep these sorted after SoC name and memory size? E.g. see
sama7g5 entries, sama5dX entries.

Could you keep this chunk after SAM9X60_* one to have some kind of
alphanumerical sort?
