[U-Boot] Bare x86 support is merged to u-boot-x86
Hi Bin (and others interested in U-Boot on x86),
I've applied the remaining x86 patches to u-boot-x86. It runs on chromebook_link (Pixel) with support for most hardware relevant to a boot loader: SDRAM, SPI, PCI, USB (and USB Ethernet), SATA (internal 32GB SSD), SD card, LCD, UART, keyboard, EC.
Bin this should be a good base for you to send patches for your Atom platform and I have no major work pending now so should not get in your way.
Instructions on how to build and run are here:
http://www.denx.de/wiki/U-Boot/X86
For this platform 4 binary blobs are needed. This is an unavoidable feature of the platform at present. The blobs cover flash descriptor, SDRAM init, video init and Management Engine. Instructions on how to get these are on the same page.
Here is a list of some missing features:
- README.x86 in the source (mostly the content from the Wiki page would be a good start) - MTRR support (for performance) - Audio - Chrome OS verified boot (only a rough rebase has been done, I'm not sure how to track mainline anyway) - SMI and ACPI support, to provide platform info and facilities to Linux

Thanks for all of your efforts on getting some x86 support into U-Boot. Hopefully in the new year when project work is back under control I will have some time to get involved with this - I have almost 20 years experience porting commercial BIOS and UEFI solutions for x86 hardware and possibly a bunch of Atom C2750 hardware arriving in January.
Other than the list of missing features, what are your long term goals/ambitions/desires with x86 support in U-Boot? From what I can see on the Coreboot mailing list it isn't the friendliest of people and doesn't seem to know how to deal with the binary blobs that both Intel and AMD seem to mandate for their chipsets now.
Andy.

This is great! Thanks for applying your patch series into the mainline so quickly. I will start working on my patches soon.

One question related to ACPI, do we need support pre-ACPI protocols for handling over resource allocations and interrupt vector assignment information to the OS? I mean the PIRQ table and MP table. These specs are really old nowadays, and even commercial BIOS does not always get those tables correct, but as far as I can see, ACPI tables are more reliable. I think this is largely because they validate ACPI support with Windows and Linux which always use ACPI.

I vote no. ACPI should be enough.

This is awesome! Thanks so much for the work you two have done on this. We've been using u-boot on our PPC platforms for years and love it. We're considering moving to an Atom processor and wanted to continue to use u-boot, but were worried about getting it up and running with the FSL from Intel so we haven't made the jump yet. This is going to be a huge leg up in my argument for actually getting that project off the ground. If we do, I'll be sure to be pushing out any work we do that isn't in the mainline.
Thanks again guys!
Bruce

Not sure yet. We had originally settled on the first one Intel put out, but since we've waited so long and we're not locked in by design yet, we'll probably pick a newer generation. Our products tend to be in service for a long time (upwards of 20 years) so we like to get as cutting edge as we can without losing a finger :)

I am currently working on patches to support Intel Atom E6xx with Platform Controller Hub EG20T. This Atom platform aims at the embedded market. More newer Atom would be Bay Trail, which is an SoC and I believe Simon is going to support that platform once he gets a board. The latest Atom would be Braswell. If Intel keeps open for the chipset datasheet, I think we can try to support that too. We will see.
