- 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.
