History

Mohamed Mansoor bde683ce9f This patch changes following in getpir application. 1 - Moved the check sum validation to probe_table function. 2 - Proper handling of resources allocated. 3 - Signature check is done in 16 byte boundaries. 4 - irq_tables.c file is created only if a valid PIRQ table is found. 5 – Makefile and README file are modified accordingly.

README

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.
