imx-imx-boot-bootpart.wks.in: Use variable to choose ptable typebackport-2584-to-wrynose
In NXP i.MX BSP, i.MX 8 & 9 is preferred to use gpt ptable:
- Boot ROM Compatibility: i.MX 8/9 Boot ROM can work with both MBR and GPT
- U-Boot Configuration: NXP U-Boot has configured to recognize GPT (CONFIG_EFI_PARTITION=y)
- Partition Alignment: GPT first usable LBA in GPT is in sector 34 (17KB), and i.MX 8&9 has IMX_BOOT_SEEK offset (32-33KB), so no conflict
- Advantages of GPT
- Support for >2TB storage (not typically relevant for SD cards)
- More robust with CRC32 checksums and backup partition table
- Up to 128 partitions vs 4 primary partitions in MBR
- Better partition naming and GUID identification
