41 | ==========================================================================================\r | |
42 | EDK_r4955: Non-Compatible: qhuang8\r | |
43 | \r | |
44 | Class_HFile: Update the Device Type Value of MEDIA_FV_DP & MEDIA_FV_FILEPATH_DP.\r | |
45 | The definitions in MdePkg have already been updated in r4632. This will remove the\r | |
46 | potential compatibility issues when native EDK II modules & EDK modules built with\r | |
47 | ECP and run with EDK II core. \r | |
48 | \r | |
49 | Code Change:\r | |
50 | 1) Reverse the value of MEDIA_FV_DP & MEDIA_FV_FILEPATH_DP to fix a UEFI errata. \r | |
51 | \r | |
52 | \r | |
53 | Possible impact:\r | |
54 | 1) EDK I modules built with this update might not work with old EDK environment. \r | |
55 | \r | |
56 | \r | |
57 | ==========================================================================================\r | |
58 | EDK_r4960: Non-Compatible: qhuang8\r | |
59 | \r | |
60 | Class_HFile: Remove the default value 0xE0000000 of EDKII_GLUE_PciExpressBaseAddress.\r | |
61 | It now requires platform DSC file to specify it explicitly to avoid runtime issue\r | |
62 | if they ever uses PciExpressLib in EDK GlueLib.\r | |
63 | Unlike other default value in GlueLib, this value might not function for all real\r | |
64 | platforms. \r | |
65 | \r | |
66 | Code Change:\r | |
67 | 1) Replace 0xE0000000 to be PCD_EDKII_GLUE_PciExpressBaseAddress. \r | |
68 | \r | |
69 | Possible impact:\r | |
70 | 1) If a platform ever uses PciExpressLib in Glue Lib. It needs to explictly specify\r | |
71 | the value of PCD_EDKII_GLUE_PciExpressBaseAddress for their platform to function.\r | |
72 | e.g. in EDK II DSC file to build EDK modules: \r | |
73 | [BuildOptions]\r | |
74 | *_*_*_CC_FLAGS = /D PCD_EDKII_GLUE_PciExpressBaseAddress=0xC0000000\r | |
75 | \r |
