REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2977 For a source-level BIOS debugger the .map files are quite useful with one major shortcoming: the debugger cannot know, solely from the .map file, the format (PE/COFF vs. TE) of the image included in the final BIOS ROM Add Type=PE or TE in the map file Cc: Bob Feng <bob.c.feng@intel.com> Cc: Liming Gao <gaoliming@byosoft.com.cn> Cc: Yuwei Chen <yuwei.chen@intel.com> Signed-off-by: Yunhua Feng <fengyunhua@byosoft.com.cn> Reviewed-by: Bob Feng <bob.c.feng@intel.com>

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.
