Hi, Intel Quark X1000 consists of two SPI controllers which can be PCI enumerated. SPI-PXA2XX PCI layer doesn't support it. Thus, we add support for Intel Quark X1000 SPI as well.
--- v4: [PATCH 1/2] * No changes. [PATCH 2/2] * Move all Quark specific macros out of #ifdef 'CONFIG_ARCH_PXA'.
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.
