There was a problem when using the getpir utility with the coreboot_ram file, basically removed the loop around the search function, in the coreboot_ram image the start $PIR is not on a 16 byte boundary. due to the search already was matching 6 bytes of the start of the table (including the version of the table), this was not necessary any more.
