In V2, update array style to more than one dimension array. In V3, Update Pcd Field value assignment with array index. BZ: https://bugzilla.tianocore.org/show_bug.cgi?id=1292 1. Support the syntax of the structure array for structure PCD 2. Add the syntax to initialize structure PCD with C style value Contributed-under: TianoCore Contribution Agreement 1.1 Signed-off-by: Liming Gao <liming....@intel.com> Cc: Bob Feng <bob.c.f...@intel.com> --- 3_edk_ii_dec_file_format/310_pcd_sections.md | 2 +- .../32_package_declaration_dec_definitions.md | 11 +++++++++-- 2 files changed, 10 insertions(+), 3 deletions(-) diff --git a/3_edk_ii_dec_file_format/310_pcd_sections.md b/3_edk_ii_dec_file_format/310_pcd_sections.md index 42beee9..2711788 100644 --- a/3_edk_ii_dec_file_format/310_pcd_sections.md +++ b/3_edk_ii_dec_file_format/310_pcd_sections.md @@ -125,7 +125,7 @@ PCDs listed in `PcdsFeatureFlag` sections must only be listed in <PcdUint32> ::= {<NumValUint32>} {<Expression>} <FS> "UINT32" <Pcd64> ::= <PcdName> <FS> <PcdUint64> <FS> <Token> <CbOrEol> <PcdUint64> ::= {<NumValUint64>} {<Expression>} <FS> "UINT64" -<PcdStruct> ::= <PcdName> <FS> <PtrVal> <FS> <CName> <FS> <Token> "{" <EOL> +<PcdStruct> ::= <PcdName> <FS> <PtrVal> <FS> {<CName>} {<CArrayName>} <FS> <Token> "{" <EOL> <TS> <PcdStructHF> <TS> <PcdStructPKGs> "}" <CbOrEol> <PcdStructHF> ::= "<HeaderFile>" <EOL> <PcdStructFile> diff --git a/3_edk_ii_dec_file_format/32_package_declaration_dec_definitions.md b/3_edk_ii_dec_file_format/32_package_declaration_dec_definitions.md index a3120f3..dc18fb0 100644 --- a/3_edk_ii_dec_file_format/32_package_declaration_dec_definitions.md +++ b/3_edk_ii_dec_file_format/32_package_declaration_dec_definitions.md @@ -87,6 +87,7 @@ DEC file (for example, `<Expression>` statements are not permitted). <NonDigit> ::= (a-zA-Z_) <Identifier> ::= <NonDigit> <Chars>* <CName> ::= <Identifier> # A valid C variable name. +<CArrayName> ::= <Identifier>["["[<Number>]"]"]+ # A valid C variable array name. <AsciiChars> ::= (0x21 - 0x7E) <CChars> ::= [{0x21} {(0x23 - 0x26)} {(0x28 - 0x5B)} {(0x5D - 0x7E)} {<EscapeSequence>}]* @@ -166,7 +167,7 @@ DEC file (for example, `<Expression>` statements are not permitted). <MACRO> ::= (A-Z)(A-Z0-9_)* <MACROVAL> ::= "$(" <MACRO> ")" <PcdName> ::= <TokenSpaceGuidCName> "." <PcdCName> -<PcdFieldName> ::= <TokenSpaceGuidCName> "." <PcdCName> "." <Field> +<PcdFieldName> ::= <TokenSpaceGuidCName> "." <PcdCName> ["["<Number>"]"]* "." <Field> <PcdCName> ::= <CName> <TokenSpaceGuidCName> ::= <CName> <PcdFieldEntry> ::= <PcdFieldName> <FS> <PcdFieldValue> <EOL> @@ -208,7 +209,7 @@ DEC file (for example, `<Expression>` statements are not permitted). <StringVal> ::= {<UnicodeString>} {<CString>} {<Array>} <Array> ::= "{" {<Array>} {[<Lable>] <ArrayVal> [<CommaSpace> [<Lable>] <ArrayVal>]* } "}" -<ArrayVal> ::= {<Num8Array>} {<GuidStr>} {<DevicePath>} +<ArrayVal> ::= {<Num8Array>} {<GuidStr>} {<DevicePath>} {<CodeStr>} <NonNumType> ::= {<BoolVal>}{<UnicodeString>} {<CString>} {<Offset>} {<UintMac>} <Num8Array> ::= {<NonNumType>} {<ShortNum>} {<UINT8>} @@ -216,6 +217,7 @@ DEC file (for example, `<Expression>` statements are not permitted). <Num32Array> ::= {<NonNumType>} {<LongNum>} {<UINT32>} <Num64Array> ::= {<NonNumType>} {<LongLongNum>} {<UINT64>} <GuidStr> ::= "GUID(" <GuidVal> ")" +<CodeStr> ::= "CODE(" <CData> ")" <GuidVal> ::= {<DblQuote> <RegistryFormatGUID> <DblQuote>} {<CFormatGUID>} {<CName>} <DevicePath> ::= "DEVICE_PATH(" <DevicePathStr> ")" @@ -326,6 +328,11 @@ All C data arrays used in PCD value fields must be byte arrays.
