| 7 | First, you need the following binary blobs: |
| 8 | |
| 9 | * descriptor.bin - Intel flash descriptor |
| 10 | * me.bin - Intel Management Engine |
| 11 | * mrc.bin - Memory Reference Code, which sets up SDRAM |
| 12 | * video ROM - sets up the display |
| 13 | |
| 14 | You can get these binary blobs by:: |
| 15 | |
| 16 | $ git clone http://review.coreboot.org/p/blobs.git |
| 17 | $ cd blobs |
| 18 | |
| 19 | Find the following files: |
| 20 | |
| 21 | * ./mainboard/google/link/descriptor.bin |
| 22 | * ./mainboard/google/link/me.bin |
| 23 | * ./northbridge/intel/sandybridge/systemagent-r6.bin |
| 24 | |
| 25 | The 3rd one should be renamed to mrc.bin. |
| 26 | As for the video ROM, you can get it `here`_ and rename it to vga.bin. |
| 27 | Make sure all these binary blobs are put in the board directory. |
| 28 | |
| 29 | Now you can build U-Boot and obtain u-boot.rom:: |
| 30 | |
| 31 | $ make chromebook_link_defconfig |
| 32 | $ make all |
