SPI-PXA2XX PCI layer doesn't support it. Thus, we add support for Intel Quark X1000 SPI as well. --- v3: [PATCH 1/2] * Improve the commit message. * A couple of minor fixes. [PATCH 2/2] * Set '.num_chipselect' to '1' instead of '4'. * A couple of minor fixes. v2: Split into two patches: one is for helper functions, and another is for quark supporting. [PATCH 1/2] * Add helper functions to access registers. * Use 'switch' instead of 'if-else'. [PATCH 2/2] * Use 'switch' instead of 'if-else'. * Add comments for the 'dds'&'clk_div' caculation. * A couple of minor fixes.
