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