I'm not sure, but at some point this is all going to get out of hand. Already we have these options:
common/spl/Kconfig:config SYS_MMCSD_RAW_MODE_U_BOOT_USE_SECTOR common/spl/Kconfig:config SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR common/spl/Kconfig:config SYS_MMCSD_RAW_MODE_U_BOOT_DATA_PART_OFFSET common/spl/Kconfig:config SYS_MMCSD_RAW_MODE_U_BOOT_USE_PARTITION common/spl/Kconfig:config SYS_MMCSD_RAW_MODE_U_BOOT_PARTITION common/spl/Kconfig:config SYS_MMCSD_RAW_MODE_U_BOOT_USE_PARTITION_TYPE common/spl/Kconfig:config SYS_MMCSD_RAW_MODE_U_BOOT_PARTITION_TYPE common/spl/Kconfig:config SYS_MMCSD_RAW_MODE_EMMC_BOOT_PARTITION common/spl/Kconfig:config SYS_MMCSD_FS_BOOT_PARTITION common/spl/Kconfig:config SYS_MMCSD_RAW_MODE_KERNEL_SECTOR common/spl/Kconfig:config SYS_MMCSD_RAW_MODE_ARGS_SECTOR common/spl/Kconfig:config SYS_MMCSD_RAW_MODE_ARGS_SECTORS
That is just for MMC raw mode.
For environment we have SYS_MMC_ENV_DEV and _PART. If you look around you'll see loads of these options.
I see that rockchip uses u-boot,spl-boot-order as a way to determine the boot order. This makes it configurable without rebuilding U-Boot...although I don't think we need to make the MMC stuff configurable, since I am assuming that the boot ROM determines at least some of it...?
This patch is about SPL loading main U-Boot. So the boot ROM is not involved.
But in that case we surely want to have a single board and SoC independent partition GUID?
No. I want to create one installation image which runs on multiple boards, e.g.
part 1, GUID 8300, /boot part 2, GUID 8300, / part 15, GUID EF00, /boot/efi part 20, GUID SPL 1, SPL for board 1 part 21, GUID U-Boot 2, U-Boot for board 1 ... part 127, GUID SPL 54, SPL for board 54 part 128, GUID U-Boot 54, U-Boot for board 54
Is this concept proposed somewhere that OS / distro people might further comment on?
