This is FSP 1.1. I’ll work on getting serial output. It shouldn’t be difficult assuming this dev board has it routed. I agree that it will make debug easier. --David Crammer From: coreboot [mailto:coreboot-bounces@coreboot.org] On Behalf Of Jin, Huang Sent: Wednesday, December 09, 2015 2:01 PM To: David Crammer Cc: coreboot(a)coreboot.org Subject: Re: [coreboot] FSPInitiNot Returning Hi David, May I know which FSP version are you using?

I submitted a patch to rename the fsp_baytrail/baytrail folder to fsp_baytrail/include/soc. https://review.coreboot.org/12686 It touched a lot of code that I don't normally compile, so I'm waiting on the build results to see what may have broke. It is all automated with grep and sed (commands in the commit message), except for the Makefile.inc change to add the folder to the include path. Please take a look. Thanks, Ben

there's another way to do this that few people use. Back in the E7500 days, the 7505 came along. We experimented with this: src/northbridge/intel/e750x and put the common files in there. Under e750x we had e7500 e7505 for the different files. so, src/northbridge/intel/e750x/{e7500,e7505} worked fine. nobody cared enough to really do the work of putting it all together, we were just happy that the build system supported the naming in the files and so on. Part of the trick is this: in the mainboard file, the part becomes src/northbridge/intel/e750x/e7500 and in e7500 you include parts from src/northbridge/intel/e750x So you don't make e750x the northbridge directory; rather you make e750x/e7505 and e750x/e7500 the directory. That way, no condition includes or anything. It's a pretty standard build setup. this is similar to what we did on the ARM parts a few years back. ron On Mon, Dec 7, 2015 at 4:08 PM Ben Gardner <gardner.ben(a)gmail.com> wrote: > On Mon, Dec 7, 2015 at 9:55 AM, Martin Roth <gaumless(a)gmail.com> wrote: > > I think we can cut down on some of the code redundancy, but as Alex > > says, they are different chipsets, and we need to be careful about > > trying to combine too much. > > > > Here are my suggested steps: > > 1) Look for commonalities between baytrail and other chipsets and move > > pieces things into soc/intel/common or southbridge/intel/common. > > Let's not do a bunch of work just for baytrail that could help all the > > intel chipsets.
