UpdateArmResetVectorIfNeeded (

  IN FV_INFO                *FvInfo
  )
/*++

Routine Description:
  This parses the FV looking for SEC and patches that address into the
  beginning of the FV header.

  For ARM32 the reset vector is at 0x00000000 or 0xFFFF0000.
  For AArch64 the reset vector is at 0x00000000.

  This would commonly map to the first entry in the ROM.
  ARM32 Exceptions:
  Reset            +0
  Undefined        +4
  SWI              +8
  Prefetch Abort   +12
  Data Abort       +16
  IRQ              +20
  FIQ              +24

  We support two schemes on ARM.
  1) Beginning of the FV is the reset vector
  2) Reset vector is data bytes FDF file and that code branches to reset vector
    in the beginning of the FV (fixed size offset).

  Need to have the jump for the reset vector at location zero.
  We also need to store the address or PEI (if it exists).
  We stub out a return from interrupt in case the debugger
   is using SWI (not done for AArch64, not enough space in struct).
  The optional entry to the common exception handler is
   to support full featured exception handling from ROM and is currently
    not support by this tool.

Arguments:
  FvImage       Memory file for the FV memory image
  FvInfo        Information read from INF file.

Returns:

  EFI_SUCCESS             Function Completed successfully.
  EFI_ABORTED             Error encountered.
  EFI_INVALID_PARAMETER   A required parameter was NULL.
