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