This commit adds support for the Broadcom STB S2/S3/S5 suspend states on MIPS based SoCs. This requires quite a lot of code in order to deal with the different HW blocks that need to be quiesced during suspend: - DDR PHY - DDR memory controller and arbiter - control processor The final steps of the suspend execute in cache and there is is a little bit of assembly code in order to shut down the DDR PHY PLL and then go into a wait loop until a wake-up even occurs. Conversely the resume part involves waiting for the DDR PHY PLL to come back up and resume executions where we left.
