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
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
