*ErasePolarity
56 This utility relocates PEI XIP PE32s in a FV.
60 argc - Number of command line arguments
62 BaseAddress The base address to use for rebasing the FV. The correct
63 format is a hex number preceded by 0x.
64 InputFileName The name of the input FV file.
65 OutputFileName The name of the output FV file.
66 MapFileName The name of the map file of relocation info.
68 Arguments come in pair in any order.
76 0 No error conditions detected.
77 1 One or more of the input parameters is invalid.
78 2 A resource required by the utility was unavailable.
79 Most commonly this will be memory allocation or file creation.
80 3 PeiRebase.dll could not be loaded.
81 4 Error executing the PEI rebase.
