[PATCH qemu 00/38] aspeed: going mainline

[Cédric Le Goater]

Hello,

This is rather large patchset which I intend to send to mainline qemu
in a couple of weeks when time permits. In there, you will find a lot
of littles fixes, some improvements on existing models and a couple of
new models which were never exposed to mainline yet. Feel free to scan
through the patches or just read the summary below and ask questions.

* SoC level 
  - an AST2400 A1 SoC for the Palmetto machine
  - a 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.

* SDMC (DRAM controller) 
  - support for new registers to fake DRAM calibration (AST2400). This
    is a good start to understand what these 3000 lines of ARM
    assembly do in the lowlevel_init routine of U-Boot. What a mess ...
  
* I2C
  - a couple more devices 
  - the current model does not support the Linux driver sent to
    mailine. This is because the irq status handling is way too
    simplistic, or even broken. Anyone has some spare cycles for it ?
  
* Watchdog 
  - new model.  
  - not complete but reset under U-Boot and reboot under Linux now
    work so I think it is time to send the model upstream.
  - needs an upstream sponsor 
  
* Network 
  - new model of the ftgmac100 device
  - the ring buffer handling is imperfect and it does not support
    U-Boot (a pity) but we need feedback else this is going to bit rot
    for another 6 months
  - NSCI fake backend

For future work, please see the wiki :

Cheers,

C.
