Notes: * Currently limited to 32-bit sector addresses due to internal Rockbox APIs. So this means a practical limit of 2TiB per drive. * Only 'General Data' GPT partition type is recognised, as that's what SD cards seem to use for exFAT/FAT32. Note that _booting_ off GPT-partitioned drive will require rebuilding the various rockbox bootloaders, and even then there may be platform limitations that preclude this.
