Hi Mike,
Some comment, please check it. thanks.
1. How about change the PcdValue as below since we also support the integer value.
<PcdValue> ::= {<Boolean>} {<Number>} {<CString>} {<CArray>}
<Number> ::= {<Integer>} {<HexNumber>}
<Integer> ::= {(0-9)} {(1-9)(0-9)+}
2. How about change HexNumber to support the upper case "0X" ?
<HexNumber> ::= {"0x"} {"0X"} (a-fA-F0-9){1,16}
3. No <HexByte> definition. How about add this one ?
<HexByte> ::= {"0x"} {"0X"} (a-fA-F0-9){1,2}
4. A typo error (it is INF, not INC) in sentence " command-line take precedence over PCD provided in DSC, FDF, INC, and DEC files".
Best Regards,
Zhu Yonghong
