soc: bcm: brcmstb: Add support for S2/S3/S5 suspend states (ARM) This commit adds support for the Broadcom STB S2/S3/S5 suspend states on ARM 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 SHIM - DDR memory controller and sequencer - control processor The final steps of the suspend execute in an on-chip SRAM and there is a little bit of assembly code in order to shut down the DDR PHY PLL and then go into a wfi 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. For S3, because of our memory hashing (actual hashing code not included for simplicity, and is bypassed) we need to relocate the writable variables (stack) into SRAM shortly before suspending in order to leave the DRAM untouched and create a reliable hash of its contents. This code has been contributed by Brian Norris initially and has been incrementally fixed and updated to support new chips by a lot of people.
