FLASH_SUBREGION_DESCRIPTION *
ParseSubregionDefinition (
unsigned int SizeLeft
)
/*++
Routine Description:
Parse Subregion definitions from the input flash definition file. Format:
Subregion {
CreateHob = TRUE,
Name = "FOO",
Size = 0xA000,
Attributes = "EFI_FLASH_AREA_SUBFV | EFI_FLASH_AREA_MEMMAPPED_FV",
AreaType = "EFI_FLASH_AREA_EFI_VARIABLES",
NameGuid = 12345678-1234-5678-AAAA-BBBBCCCCDDDD (or "EFI_SOME_GUID"),
AreaTypeGuid = 11111111-2222-3333-4444-1, (or "EFI_SOME_GUID") (optional)
FileSystemGuid = 11111111-2222-3333-4444-1, (or "EFI_SOME_GUID") (optional)
}
NOTE: The caller has already parsed the "Subregion" token, so start with the opening brace.
Arguments:
SizeLeft - in the flash definition file, a Region can be broken up into
one or more subregions. As we parse the subregion definitions,
the caller keeps track of how much space is left in the region
that we're parsing subregions for. SizeLeft is that size, and
so the size of the subregion we're now parsing better not
exceed the size left.
Returns:
NULL - unrecoverable errors detected while parsing the subregion definition
pointer to a subregion definition created from the parsed subregion
