- *
- * EFI platform error codes
- *
- * We derive our platform error codes from the possible values for
- * EFI_STATUS defined in the UEFI specification.
- *
- * EFI_STATUS codes are 32/64-bit values consisting of a top bit which
- * is set for errors and clear for warnings, and a mildly undefined
- * code of low bits indicating the precise error/warning code. Errors
- * and warnings have completely separate namespaces.
- *
- * We assume that no EFI_STATUS code will ever be defined which uses
- * more than bits 0-6 of the low bits. We then choose to encode our
- * platform-specific error by mapping bit 31/63 of the EFI_STATUS to
- * bit 7 of the platform-specific error code, and preserving bits 0-6
- * as-is.
