/**
* @file
*
* 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.
