2056Routine Description:\r
2057 This parses the FV looking for SEC and patches that address into the \r
2058 beginning of the FV header.\r
2059\r
2060 For ARM32 the reset vector is at 0x00000000 or 0xFFFF0000.\r
2061 For AArch64 the reset vector is at 0x00000000.\r
2062\r
2063 This would commonly map to the first entry in the ROM. \r
2064 ARM32 Exceptions:\r
2065 Reset +0 \r
2066 Undefined +4\r
2067 SWI +8\r
2068 Prefetch Abort +12\r
2069 Data Abort +16\r
2070 IRQ +20\r
2071 FIQ +24\r
2072\r
2073 We support two schemes on ARM.\r
2074 1) Beginning of the FV is the reset vector\r
2075 2) Reset vector is data bytes FDF file and that code branches to reset vector \r
2076 in the beginning of the FV (fixed size offset).\r
2077\r
2078 Need to have the jump for the reset vector at location zero.\r
2079 We also need to store the address or PEI (if it exists).\r
2080 We stub out a return from interrupt in case the debugger \r
2081 is using SWI (not done for AArch64, not enough space in struct).\r
2082 The optional entry to the common exception handler is \r
2083 to support full featured exception handling from ROM and is currently \r
2084 not support by this tool.\r
