That seems a bit harsh to me, but I'm not against it. Again, just my 2 cents. Another (softer) approach would be to mark the board as deprecated/unstable in the build/kconfig, and then remove it from the tree if it's not tested by the next release.

Re: [coreboot] Changing console uart on Bayley Bay CRB
by Gailu Singh 07 Nov '14

07 Nov '14

Hi, I got the schematics now and I see that J9B4 is connected to Embedded Controller (EC), so I think that this is not 8250 UART2. Am I right? I am not able to find the documentation what purpose is served by Embedded Controller and does coreboot use it at all? Any pointers please. I am trying to understand what is the purpose of COM port at J9B4. Any specific document that I should refer to to understand it? I checked user guide and schematics. There are 2 com ports I see using usb to serial and Port0 is used for console. Is another port on usb to serial is spare and can be used for console or is it serving some other purpose in coreboot.

Changing console uart on Bayley Bay CRB
by Gailu Singh 07 Nov '14

07 Nov '14

Hi Experts, I have working console uart 0 on Baytrail CRB board. However I am trying to change to uart 2 (J9B4) DB9 connector. I have changed CONFIG_UART_FOR_CONSOLE=2 from menuconfig, cleaned and rebuild and flashed coreboot but do not see any log on port 2. Is there any other changes required apart from CONFIG_UART_FOR_CONSOLE ?

If we want to go for a library, we should also handle redistribution issues - vgabios, various firmware could be extracted from the running system or downloaded images and compared against known-good hashes, then added to partial images. > So how about we forget about release cycles for the tree and think in > terms of the problem of distribution of good images for people? Does > that make things easier? I don't know. The concern with having buildable source for users is relevant for a certain groups of tinkerers and vendors alike. The former build everything from source (because they have unusual demands on their firmware), the latter want to be able to point to working code for reference boards that can serve as template for further development. Since the most recent request was about keeping certain parts of the code stable, that's what I ran with. Patrick

Based on the community feedback and this email discussion, isolation of the PI and AGESA source is the preferred development path. While we were trying for a common interface, it is not necessary. I concede that AMD has not contributed updates to AGESA releases and has had poor community interactions. It should be more beneficial to the development of coreboot to fix the long standing issues in the code. I have removed my NACK(-2) on 7149 and it should be un-abandoned. Thanks to each of you to your contributions and improvements to coreboot. Regards, Marc -- http://se-eng.com

Meng Qiaohui, I noticed a file called ChangesRequiredForRambiWinboot.txt in Intel released UEFI package, it can tell you how to modify coreboot/ACPI files to boot Windows 7, you can download the package @ http://uefidk.intel.com/sites/default/files/2014-WW26-UEFI.CoreBoot.Payload…, its decryption key @ http://uefidk.intel.com/sites/default/files/2014-WW26-UEFI.CoreBoot.Payload… and release note @ http://uefidk.intel.com/sites/default/files/2014-WW26-UEFI.CoreBoot.Payload… . If you want to fully understand ACPI, go to http://www.acpi.info/ to download the ACPI specification, reading it and practicing with your Bayley Bay coreboot code is the best way to understand it. -Fei On Tue, Nov 4, 2014 at 3:07 AM, <mengqiaohui(a)mindray.com> wrote: > ------------------------------ > > Hi，expert. > > Now Coreboot with Intel FSP ,can load Linux on my BayleyBay.I > tried to use Seabios 1.7.5 load Win7 64bit,but i got a blue screen > issue,stop at A5(0x1000,0x000,0x105a23a1,0x100).Obviously I think this > trouble was called by ACPI.Am I wrong?
