/*
|
|
* 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.
