[U-Boot] [PATCH v7 00/13] 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.

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.

Álvaro Fernández Rojas (13):
  wait_bit: add 8/16/32 BE/LE versions of wait_for_bit
  wait_bit: use wait_for_bit_le32 instead of wait_for_bit
  wait_bit: remove old wait_for_bit function
  drivers: spi: allow limiting reads
  drivers: spi: consider command bytes when sending transfers
