The option statement has the following flags:
oneofoptionFlagsField ::=
Number
| "OPTION_DEFAULT"
| "OPTION_DEFAULT_MFG"
| "INTERACTIVE"
| "RESET_REQUIRED"
| "DEFAULT"
But it is not clear what the "INTERACTIVE" and "RESET_REQUIRED" flags should
do. Are they OR'd together and put in the parent question?
There are many other flags in the grammar that are undocumented. For example:
LATE_CHECK or NV_ACCESS. These flags values are also not defined in the UEFI
specification. Is there any further definition or are these from the older
Framework spec? If they are from the Framework spec, is there some way to add
error checking so that they can be excluded?
oneofoptionFlagsField [UINT8 & HFlags, UINT8 & LFlags] :
N:Number << $LFlags |=
_STOU8(N->getText(), N->getLine()); >>
| "OPTION_DEFAULT" << $LFlags |= 0x10; >>
| "OPTION_DEFAULT_MFG" << $LFlags |= 0x20; >>
| InteractiveFlag << $HFlags |= 0x04; >>
| NVAccessFlag << $HFlags |= 0x08; >>
| ResetRequiredFlag << $HFlags |= 0x10; >>
| LateCheckFlag << $HFlags |= 0x20; >>
| ManufacturingFlag << $LFlags |= 0x20; >>
| DefaultFlag << $LFlags |= 0x10; >>
;
