[Qemu-devel] [PATCH for-2.9 00/30] Aspeed SoC fixes and model improvements

[Cédric Le Goater]

Here is a collection of fixes and improvements on existing models for
the Aspeed SoCs

 * Block
   - add a 'model' option to -drive for MTD devices  

 * SoC level 
   - an AST2400 A1 SoC for the Palmetto machine
   - a new Romulus machine  
   - a SRAM region (which is used at early boot in U-Boot, serves as a
     stack, and by DRAM calibration)

 * SMC (Flash controller) 
   - Command mode support. Flash contents is accessed directly on the
     AHB bus   
   - DMA support
   - dummy bytes
   - auto strapping of configuration for boot flash
   - use CS0 as a boot ROM. Today, qemu can not boot from a MMIO region.
     As this is complex to do (TCG layer modification), we use a ROM
     region in which we copy the flash contents. Hopefully, I got it 
     right this time.

 * Watchdog 
   - new model.  
   - not complete but reset under U-Boot and reboot under Linux now
     work    

Thanks,

C.
