When reading or writing MHI registers, the core assumes that the physical link is a memory mapped PCI link. This assumption may not hold for all MHI devices. The controller knows what is the physical link (ie PCI, I2C, SPI, etc), and therefore knows the proper methods to access that link. The controller can also handle link specific error scenarios, such as reading -1 when the PCI link went down. Therefore, it is appropriate that the MHI core requests the controller to make register accesses on behalf of the core, which abstracts the core from link specifics, and end up removing an unnecessary assumption.
