[RFC PATCH 00/13] spi: dw: Add support for XIP mode

This adds support for memory-mapped ("DIRMAP") reads (called XIP by the datasheet). In theory, these have better performance than regular reads. In practice, the CPU is already fast enough to max out the performance of this peripheral. The real end-goal is to be able to boot a XIP kernel. This SoC
