Is FW_BLOBS needed? |
||
Issue descriptionIn https://chrome-internal-review.googlesource.com/c/375491/ we added FW_BLOBS. We use it to add a file that seems to be related to baseboard-reef. There is already a mechanism in the coreboot build to use files in /firmware/coreboot-private How come we don't install the ps8751_a3.bin into /firmware/coreboot-private/3rdparty/blobs/baseboard-reef ? Also how come it is installed after the emake within the coreboot ebuild? Does the coreboot Makefile not know about this file? Thanks!

the scheme we use to import this blob (there will be more) is modeled after the scheme we use for ec (ec*.bin) and pd (pdrw). see coreboot*.ebuild:add_ec() and PD_FIRMWARE and PD_SYNC in the various overlay make.conf files. if there's enough interest, we can refactor how we import these blobs, but as far as i can tell, this is WAI at this point. coreboot itself doesn't care about this blob. depthcharge needs it to flash the peripheral(s) during the software sync phase. |
