2017-03-06IntelFsp2WrapperPkg: Refine casting expression result to bigger sizeHao Wu1-5/+5
There are cases that the operands of an expression are all with rank less than UINT64/INT64 and the result of the expression is explicitly cast to UINT64/INT64 to fit the target size. An example will be: UINT32 a,b; // a and b can be any unsigned int type with rank less than UINT64, like // UINT8, UINT16, etc. UINT64 c; c = (UINT64) (a + b); Some static code checkers may warn that the expression result might overflow within the rank of "int" (integer promotions) and the result is then cast to a bigger size. The commit refines codes by the following rules: 1). When the expression is possible to overflow the range of unsigned int/ int: c = (UINT64)a + b; 2). When the expression will not overflow within the rank of "int", remove the explicit type casts: c = a + b; 3). When the expression will be cast to pointer of possible greater size: UINT32 a,b; VOID *c; c = (VOID *)(UINTN)(a + b); --> c = (VOID *)((UINTN)a + b); 4). When one side of a comparison expression contains only operands with rank less than UINT32: UINT8 a; UINT16 b; UINTN c; if ((UINTN)(a + b) > c) {...} --> if (((UINT32)a + b) > c) {...} For rule 4), if we remove the 'UINTN' type cast like: if (a + b > c) {...} The VS compiler will complain with warning C4018 (signed/unsigned mismatch, level 3 warning) due to promoting 'a + b' to type 'int'.

2016-05-13Add IntelFsp2Pkg and IntelFsp2WrapperPkg.Jiewen Yao6-0/+900
Add FSP2.0 support. This series of patch is to support FSP2.0 specification at https://firmware.intel.com/sites/default/files/FSP_EAS_v2.0_Draft%20External.pdf Some major updates include: 1) One FSP binary is separated to multiple components: FSP-T, FSP-M, FSP-S, and optional FSP-O. Each component has its own configuration data region. 2) All FSP-APIs use same UPD format - FSP_UPD_HEADER. 3) Add EnumInitPhaseEndOfFirmware notifyphase. 4) FSP1.1/FSP1.0 compatibility is NOT maintained. 5) We also add rename Fsp* to FspWrapper* in IntelFsp2WrapperPkg, to indicate that it is for FspWrapper only. IntelFspPkg and IntelFspWrapperPkg will be deprecated. The new Intel platform will follow FSP2.0 and use IntelFsp2Pkg and IntelFsp2WrapperPkg. The old platform can still use IntelFspPkg and IntelFspWrapperPkg for compatibility consideration.
