/*
 * Test method is:
 *
 * 1) Create a mock regmap in cache-only mode so that all writes will be cached.
 * 2) Create a XM header with an algorithm list in the cached regmap.
 * 3) Create dummy wmfw file to satisfy cs_dsp.
 * 4) Create bin file content.
 * 5) Call cs_dsp_power_up() with the bin file.
 * 6) Readback the cached value of registers that should have been written and
 *    check they have the correct value.
 * 7) All the registers that are expected to have been written are dropped from
 *    the cache (including the XM header). This should leave the cache clean.
 * 8) If the cache is still dirty there have been unexpected writes.
 *
 * There are multiple different schemes used for addressing across
 * ADSP2 and Halo Core DSPs:
 *
 *  dsp words:	The addressing scheme used by the DSP, pointers and lengths
 *		in DSP memory use this. A memory region (XM, YM, ZM) is
 *		also required to create a unique DSP memory address.
 *  registers:	Addresses in the register map. Older ADSP2 devices have
 *		16-bit registers with an address stride of 1. Newer ADSP2
 *		devices have 32-bit registers with an address stride of 2.
 *		Halo Core devices have 32-bit registers with a stride of 4.
 *  unpacked:	Registers that have a 1:1 mapping to DSP words
 *  packed:	Registers that pack multiple DSP words more efficiently into
 *		multiple 32-bit registers. Because of this the relationship
 *		between a packed _register_ address and the corresponding
 *		_dsp word_ address is different from unpacked registers.
 *		Packed registers can only be accessed as a group of
 *		multiple registers, therefore can only read/write a group
 *		of multiple DSP words.
 *		Packed registers only exist on Halo Core DSPs.
 *
 * Addresses can also be relative to the start of an algorithm, and this
 * can be expressed in dsp words, register addresses, or bytes.
