> parseInfFile currently reading the EFI_BASE_ADDRESS from INF, once the
> address found still it's continues to read the complete inf file which is not
> required. once the EFI_BASE_ADDRESS read from the INF no need to read the
> INF further.
> MSFT compiler can generate the map file address 8 or 16 based on which
> architecture the INF is compiler. currently it's support for IA32, modified the
> patchfv to support for all.
> modification of few typo errors in parseModMapFile, getCurr function required
> 
> verification : Working Fine
