Rashmica,

This looks much nicer !  

Please take a look at branch aspeed-4.2 in which I have merged your
v5 and modified slightly the ast2600 part. 

  
https://github.com/legoater/qemu/commit/02b3df3f1a380eec4df7c49e88fa7ba27f75a610

I introduced a gpio_1_8v controller with its specific MMIO and IRQ
definitions. Tell me what you think of it. The principal motivation
behind these adjustments is that I don't know yet how we are going 
to instantiate/realize the specific models of the AST2600 SoC. the 
GPIO 1.8v is one of these extra controllers. 

Thanks,

C.
