Intel Quark SoC has a low end x86 processor with only 400MHz frequency. Currently it takes about 15 seconds for U-Boot to boot to shell and the most time consuming part is with MRC, which is about 12 seconds. MRC programs lots of registers on the SoC internal message bus indirectly accessed via pci
