[U-Boot] [PATCH v4 00/10] mips: bmips: add SPI support

[Álvaro Fernández Rojas]

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.

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.
