1568 Routine Description:
1569 This parses the FV looking for SEC and patches that address into the

1571
1572 For ARM the reset vector is at 0x00000000 or 0xFFFF0000.
1573 This would commonly map to the first entry in the ROM.
1574 ARM Exceptions:
1575 Reset +0
1576 Undefined +4
1577 SWI +8
1578 Prefetch Abort +12
1579 Data Abort +16
1580 IRQ +20
1581 FIQ +24
1582
1583 We support two schemes on ARM.
1584 1) Beginning of the FV is the reset vector
1585 2) Reset vector is data bytes FDF file and that code branches to reset vector
1586 in the beginning of the FV (fixed size offset).
1587
1588
1589 Need to have the jump for the reset vector at location zero.
1590 We also need to store the address or PEI (if it exists).
1591 We stub out a return from interrupt in case the debugger
1592 is using SWI.
1593 The optional entry to the common exception handler is
1594 to support full featured exception handling from ROM and is currently
