-ABOUT:
-
-This utility will help to create irq_table.c file, that is very hard to create
-manually, specialy when you are testing new motherboards, changing your
-hardware often, placing new cards, etc..
-
-USAGE:
-
-Steps
-1. make distclean;
-2. make getpir
-3. ./getpir
-
- Will dump irq table to the file called irq_tables.c, ready to use with
- coreboot. Just move the file to corresponding place in the coreboot tree.
-
-
-4. CHECKING CUSTOM irq_tables.c:
-
- make checkpir
- ./checkpir
-
- checkpir.c Will verify the irq_tables.c, currently it only checks the
- checksum. In case of wrong checksum, a good value is proposed, so you can
- edit irq_tables.c manualy and replace checksum.
-
-
-Do not run make checkpir and ./checkpir directly because it needs to be linked
-to irq_table.o first.
-
