The assignment of block device nodes in Linux is not deterministic by default, i.e. a newly added eMMC controller or other block device can change the assignment of /dev/mmcblkN (or other block device node like e.g. /dev/sdXy) and prevent the system from picking the correct block device for root filesystem in case the root filesystem is specified on kernel command line using 'root=/dev/mmcblkNpM' (or 'root=/dev/sdXy' etc.). One way out is to derive PARTUUID in U-Boot, which is unique identifier of a partition, and pass that as root=PARTUUID=<partuuid> to Linux via kernel command line. Linux would then find the partition using PARTUUID, no matter on which block device the partition resides and which node was assigned to that block device. Derive the PARTUUID before scanning for extlinux presence and assign it into distro_bootpart_uuid environment variable, which can then be used in extlinux.conf kernel command line specifier. Note that it is not possible to do this in scan_dev_for_extlinux script because this script is called from scan_dev_for_boot script, which is called for both block devices as well as UBI volumes, and we can not derive PARTUUID for UBI volumes.

* A note on error handling: It is possible for BOOT_TARGET_DEVICES to
|
|
* reference a device that is not enabled in the U-Boot configuration, e.g.
|
|
* it may include MMC in the list without CONFIG_CMD_MMC being enabled. Given
|
|
* that BOOT_TARGET_DEVICES is a macro that's expanded by the C pre-processor
|
|
* at compile time, it's not possible to detect and report such problems via
|
|
* a simple #ifdef/#error combination. Still, the code needs to report errors.
|
|
* The best way I've found to do this is to make BOOT_TARGET_DEVICES expand to
|
|
* reference a non-existent symbol, and have the name of that symbol encode
|
|
* the error message. Consequently, this file contains references to e.g.
|
|
* BOOT_TARGET_DEVICES_references_MMC_without_CONFIG_CMD_MMC. Given the
|
|
* prevalence of capitals here, this looks like a pre-processor macro and
|
|
* hence seems like it should be all capitals, but it's really an error
|
|
* message that includes some other pre-processor symbols in the text.
