It adds Dual Data support and read training giving the best read settings for a given chip. Support for the new AST2600 SoC is added at the end. I understand that a new spi_mem framework exists and I do have an experimental driver using it. But unfortunately, it is difficult to integrate the read training. The Aspeed constraints are not compatible and i haven't had the time to extend the current framework. This patchset has been in use for some time in the OpenBMC kernel on these systems : * OpenPOWER Palmetto (AST2400) * Evaluation board (AST2500) * OpenPOWER Witherspoon (AST2500) * OpenPOWER Romulus (AST2500) * OpenPOWER Zaius (AST2500) and many others and it is now in use on these boards with the new SoC : * Evaluation board (AST2600) * Tacoma board (AST2600) Thanks, C.
