BaseTools/BinToPcd: Add support for multiple binary input files
https://bugzilla.tianocore.org/show_bug.cgi?id=890 There are use cases where a VOID * PCD needs to be generated from multiple binary input files. This can be in the form of an array of fixed size elements or a set of variable sized elements. Update BinToPcd to support multiple one or more -i INPUTFILE arguments. By default, the contents of each binary input file are concatenated in the order provided. This supports generating a PCD that is an array of fixed size elements Add -x, --xdr flags to BinToPcd to encodes the PCD using the Variable-Length Opaque Data of RFC 4506 External Data Representation Standard (XDR). https://tools.ietf.org/html/rfc4506 https://tools.ietf.org/html/rfc4506#section-4.10 The data format from RFC 4506 meets the requirements for a PCD that is a set of variable sized elements in the Variable-Length Opaque Data format. The overhead of this format is a 32-bit length and 0 to 3 bytes of padding to align the next element at a 32-bit boundary.

BaseTools/Scripts: Add BinToPcd utility
https://bugzilla.tianocore.org/show_bug.cgi?id=228 Add a utility that converts a binary file into a VOID* PCD value or a full DSC file VOID* PCD statement with support for all the DSC supported PCD sections. usage: BinToPcd [-h] [--version] -i INPUTFILE [-o OUTPUTFILE] [-p PCDNAME] [-t {VPD,HII}] [-m MAXSIZE] [-f OFFSET] [-n VARIABLENAME] [-g VARIABLEGUID] [-v] [-q] [--debug [0-9]] Convert a binary file to a VOID* PCD value or DSC file VOID* PCD statement. Copyright (c) 2016, Intel Corporation. All rights reserved. optional arguments: -h, --help show this help message and exit --version show program's version number and exit -i INPUTFILE, --input INPUTFILE Input binary filename -o OUTPUTFILE, --output OUTPUTFILE Output filename for PCD value or PCD statement -p PCDNAME, --pcd PCDNAME Name of the PCD in the form <PcdTokenSpaceGuidCName>.<PcdCName> -t {VPD,HII}, --type {VPD,HII} PCD statement type (HII or VPD). Default is standard. -m MAXSIZE, --max-size MAXSIZE Maximum size of the PCD. Ignored with --type HII. -f OFFSET, --offset OFFSET VPD offset if --type is VPD. UEFI Variable offset if --type is HII. -n VARIABLENAME, --variable-name VARIABLENAME UEFI variable name. Only used with --type HII. -g VARIABLEGUID, --variable-guid VARIABLEGUID UEFI variable GUID C name. Only used with --type HII. -v, --verbose Increase output messages -q, --quiet Reduce output messages --debug [0-9] Set debug level This utility can be used in PCD value mode to convert a binary file into a string that can then be copied into the PCD value field of a VOID* PCD. The following is an example of PCD value mode on an 8 byte test.bin file. BinToPcd.py -i test.bin {0x48, 0x65, 0x6c, 0x6c, 0x6f, 0x20, 0x0d, 0x0a} The DSC file VOID* PCD statement mode can be used to generate a complete PCD statement for the PCD section types that a DSC file supports: [PcdsFixedAtBuild] [PcdsPatchableInModule] [PcdsDynamicDefault] [PcdsDynamicExDefault] [PcdsDynamicVpd] [PcdsDynamicExVpd] [PcdsDynamicHii] [PcdsDynamicExHii] The PCD statement mode is useful when combined with a !include statement in a DSC file. BinToPcd.py can be used to convert a binary file to a PCD statement in an output file, and that output file can be included into a DSC file in the matching PCD section to set the value of the PCD to the value from the binary file without having to copy the value into the DSC file. Updates can be made to the included file without editing the DSC file. Some example use cases are the setting the public key PCDs such as: gEfiSecurityPkgTokenSpaceGuid.PcdRsa2048Sha256PublicKeyBuffer gEfiSecurityPkgTokenSpaceGuid.PcdPkcs7CertBuffer The following example converts a public key binary file to a [PcdsFixedAtBuild] compatible PCD statement: BinToPcd.py -i PublicKey.bin -o PublicKey.pcd --pcd gEfiSecurityPkgTokenSpaceGuid.PcdPkcs7CertBufferkenSpaceGuid The PublicKey.pcd output file contains a single line: gEfiSecurityPkgTokenSpaceGuid.PcdPkcs7CertBuffer|{0x48, ...} A DSC file can be updated to include the PublicKey.pcd file: [PcdsFixedAtBuild] !include PublicKey.pcd Value examples =============== BinToPcd.py -i test.bin {0x68, 0x65, 0x6c, 0x6c, 0x6f, 0x20, 0x0d, 0x0a} Normal examples: ================= BinToPcd.py -i test.bin -p Guid.Token Guid.Token|{0x68, 0x65, 0x6c, 0x6c, 0x6f, 0x20, 0x0d, 0x0a} BinToPcd.py -i test.bin -p Guid.Token -m 20 Guid.Token|{0x68, 0x65, 0x6c, 0x6c, 0x6f, 0x20, 0x0d, 0x0a}|VOID*|20 VPD examples: ============= BinToPcd.py -i test.bin -p Guid.Token -t VPD Guid.Name|*|8|{0x48, 0x65, 0x6c, 0x6c, 0x6f, 0x20, 0x0d, 0x0a} BinToPcd.py -i test.bin -p Guid.Token -t VPD -f 20 Guid.Name|20|8|{0x48, 0x65, 0x6c, 0x6c, 0x6f, 0x20, 0x0d, 0x0a} BinToPcd.py -i test.bin -p Guid.Token -t VPD -m 10 Guid.Name|*|10|{0x48, 0x65, 0x6c, 0x6c, 0x6f, 0x20, 0x0d, 0x0a} BinToPcd.py -i test.bin -p Guid.Token -t VPD -f 20 -m 10 Guid.Name|20|10|{0x48, 0x65, 0x6c, 0x6c, 0x6f, 0x20, 0x0d, 0x0a} HII examples: ============= BinToPcd.py -i test.bin -p Guid.Token -t HII -g VarGuid -n VarName Guid.Name|L"VarName"|VarGuid|0|{0x48, 0x65, 0x6c, 0x6c} BinToPcd.py -i test.bin -p Guid.Token -t HII -g VarGuid -n VarName -f 8 Guid.Name|L"VarName"|VarGuid|8|{0x48, 0x65, 0x6c, 0x6c} Cc: Yonghong Zhu <yonghong.zhu@intel.com> Cc: Liming Gao <liming.gao@intel.com> Contributed-under: TianoCore Contribution Agreement 1.0 Signed-off-by: Michael Kinney <michael.d.kinney@intel.com> Reviewed-by: Liming Gao <liming.gao@intel.com> Reviewed-by: Yonghong Zhu <yonghong.zhu@intel.com> |
