[PATCH] CI: x86: coreboot: Update to latest coreboot

[Simon Glass]

Use a recent coreboot build for this test.

The coreboot commit is:

   6f5ead14b4 mb/google/nissa/var/joxer: Update eMMC DLL settings

This is build with default settings, i.e. QEMU x86 i440fx/piix4

Add some documentation as to how to update it next time.

+coreboot in CI
+--------------
+
+CI runs tests using a pre-built coreboot image. This ensures that U-Boot can
+boot as a coreboot payload, based on a known-good build of coreboot.
+
+To update the `coreboot.rom` file which is used:
+
+#. Build coreboot with `CONFIG_LINEAR_FRAMEBUFFER=y`. If using `make menuconfig`
+   this is under
+   `Devices ->Display->Framebuffer mode->Linear "high resolution" framebuffer`.
+
+#. Compress the resulting `coreboot.rom`::
+
+      xz -c /path/to/coreboot/build/coreboot.rom >coreboot.rom.xz
+
+#. Upload the file to Google drive
+
+#. Send a patch to change the file ID used by wget in the CI yaml files.
