2015-02-06x86: Use tab instead of space to indent in PCIE_ECAM_BASEBin Meng
Space is used before 'default' in PCIE_ECAM_BASE in arch/x86/Kconfig so it looks misaligned. Replace the space with tab to indent. Signed-off-by: Bin Meng <bmeng.cn@gmail.com> Acked-by: Simon Glass <sjg@chromium.org>

2015-02-06x86: Add SPI support to quark/galileoBin Meng
The Quark SoC contains a legacy SPI controller in the legacy bridge which is ICH7 compatible.

2015-02-06x86: Add support for Intel Minnowboard MaxSimon Glass
This is a relatively low-cost x86 board in a small form factor. The main peripherals are uSD, USB, HDMI, Ethernet and SATA. It uses an Atom 3800 series CPU. So far only the dual core 2GB variant is supported. This uses the existing FSP support. Binary blobs are required to make this board work. The microcode update is included as a patch (all 3000 lines of it).

2015-02-06x86: Allow a UART to be set up before the FSP is readySimon Glass

2015-02-06x86: mmc: Move common FSP functions into a common fileSimon Glass
Since these board functions seem to be the same for all boards which use FSP, move them into a common file. We can adjust this later if future FSPs need more flexibility.

2015-01-24x86: Implement a cache for Memory Reference Code parametersSimon Glass
The memory reference code takes a very long time to 'train' its SDRAM interface, around half a second. To avoid this delay on every boot we can store the parameters from the last training sessions to speed up the next. Add an implementation of this, storing the training data in CMOS RAM and SPI flash.

2015-01-23x86: Test mtrr support flag before accessing mtrr msrBin Meng
On some x86 processors (like Intel Quark) the MTRR registers are not supported. This is reflected by the CPUID (EAX 01H) result EDX[12]. Accessing the MTRR registers on such processors will cause #GP so we must test the support flag before accessing MTRR MSRs.

Note the symbolic link file chromebook_link.dts is deleted and link.dts is renamed to chromebook_link.dts.
