| /* |
| * 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. |
