Hi David,

While trying an ARM BE kernel for kinks, the 3 drivers below started not
working and the reasons why became pretty obvious because the register space
remains LE (hardwired), except for Broadcom MIPS where it follows the CPU's
native endian (let's call that a feature).

Thanks!

Changes in v2:

- correctly set RSB_SWAP1 and RSB_SWAP0 for all combinations, now properly
  tested on SYSTEMPORT (BCM7445), SYSTEMPORT Lite (BCM7278) under both endian

Florian Fainelli (4):
  net: systemport: Use correct I/O accessors
  net: dsa: bcm_sf2: Use correct I/O accessors
  net: systemport: Set correct RSB endian bits based on host
  net: phy: mdio-bcm-unimac: Use correct I/O accessors
