[PATCH 00/10] mtd: spi-nor: aspeed: support extensions

[Cédric Le Goater]

Hello,

Here is a series extending the support for the Aspeed AST2500 and
AST2400 SMC driver. First is a couple of simple fixes, then comes
support for :

 - DMA which applies to the FMC (BMC Firmware) controller only.
 - Dual Data (Quad is not supported by the controller). The spi-nor
   table of chips is modified to activate DUAL mode on the chips used
   on OpenPOWER systems. 
 - Configuration of the segment registers defining the mapping windows
   of the chips on the AHB bus.
 - Command mode for reads. Reads are performed directly on the mapping
   windows of the chip on the AHB Bus.
 - Read mode optimization, calculating the best settings for a given
   chip (for the SPI controllers only)

Tested on:

 * OpenPOWER Palmetto (AST2400)
 * Evaluation board (AST2500) 
 * OpenPOWER Witherspoon (AST2500)
 * OpenPOWER Romulus (AST2500)
 * OpenPOWER Zaius (AST2500)

Thanks,

C.
