BCM63xx SPI controller is a bit tricky since it doesn't allow keeping CS active between transfers, so I had to modify the spi_flash driver in order to allow limiting reads.
v8: Introduce changes suggested by Jagan Teki & Daniel Schwierzeck: - Squash wait_bit commits. - Remove register param castings. v7: Introduce changes suggested by Jagan Teki & Daniel Schwierzeck: - Use const void* reg for compatibility with 64 bit systems. - Remove prefix and use __func__ instead. - Remove wait_for_bit and update callers to wait_for_bit_le32. v6: Introduce changes suggested by Jagan Teki: - Use cmd instead of val to avoid confusions. - Switch to wait_for_bit instead of infinite loop. v5: Introduce changes suggested by Jagan Teki: - Use long structs for registers v4: Introduce changes suggested by Jagan Teki: - Add data for each HW controller instead of having two separate configs. v3: Fix bug introduced in v2: sizeof(cmd) vs len. Also rename BCM6338 SPI driver to BCM6348 SPI since BCM6338 is a stripped down version of the BCM6348. Switch to devfdt_get_addr_size_index(). v2: Introduce changes requested by Simon Glass: - Always include command bytes when determining max write size. Also move SPI aliases from .dts to .dtsi files.
