/*
 * 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.

	20	* The best way I've found to do this is to make BOOT_TARGET_DEVICES expand to
	21	* reference a non-existent symbol, and have the name of that symbol encode
	22	* the error message. Consequently, this file contains references to e.g.
	23	* BOOT_TARGET_DEVICES_references_MMC_without_CONFIG_CMD_MMC. Given the
	24	* prevalence of capitals here, this looks like a pre-processor macro and
	25	* hence seems like it should be all capitals, but it's really an error
	26	* message that includes some other pre-processor symbols in the text.
