Thanks for pointing out layout option. But it still accepts 16MB image as argument.
true, but it will only "use" the part that is needed to fill the address range defined by the layout file. so this should be already sufficient for you?
Is there a way where i can select the second chip and give only 8MB image file ?.
not without patches. there is a patch to specify a file per layout image: http://patchwork.coreboot.org/patch/3486/
Just curious:
How to select the SPI flash chip using CS on ICH9 ? ICH9 doc states that CS can used to select the chip but didn't have enough information on how to program CS.
Is hwseq only solution for accessing multiple chips ?.
afaik hwseq is the only option because there is no (publicly documented?) access to any register that allows to toggle CS by the host software. we have studied all public and some non-public intel documents to no avail.
