Hi Experts, On Intel Leafhill board grub fails to find cbfsdisk. We tried to debug and found that cbfs header address validation fails.
According to https://github.com/mrnuke/coreboot/blob/master/documentation/cbfs.txt, "A pointer to the location of the header will be located at offset -4 from the end of the ROM. This translates to address 0xFFFFFFFC on a normal x86 system. The pointer will be to physical memory somewhere between - 0xFFFFB000 and 0xFFFFFFF0". We checked the coreboot.rom in hex editor and address in last 4 bytes is all ones (FFFFFFFF) as a result grub is not able to find cbfs header. We have earlier used coreboot on baytrail and in the coreboot.rom cbfs header address in last 4 byte was a valid pointer. What is the location grub can find cbfs header on this board?
