on other x86 boards since coreboot deals with most of the low-level details.
U-Boot also supports booting directly from x86 reset vector without coreboot,
aka raw support or bare support. Currently Link, Intel Crown Bay and Intel
Minnowboard Max support running U-Boot 'bare metal'.

As for loading an OS, U-Boot supports directly booting a 32-bit or 64-bit
Linux kernel as part of a FIT image. It also supports a compressed zImage.

Intel Galileo instructions:
Only one binary blob is needed for Remote Management Unit (RMU) within Intel
Quark SoC. Not like FSP, U-Boot does not call into the binary. The binary is
needed by the Quark SoC itself.
You can get the binary blob from Quark Board Support Package from Intel website:
* ./QuarkSocPkg/QuarkNorthCluster/Binary/QuarkMicrocode/RMU.bin
Rename the file and put it to the board directory by:
$ cp RMU.bin board/intel/galileo/rmu.bin

These notes are for those who want to port U-Boot to a new x86 platform.
Since x86 CPUs boot from SPI flash, a SPI flash emulator is a good investment.
