Hi all,
Now I've converted the previous RFC (v2) to PATCH.
Compared with RFC v2 [1], this version mianly have the following
changes:
* Make PMU related QAPIs accept decimal value instead of string.
* Introduce a three-level QAPI section to organize KVM PMU stuff.
* Fix QAPI related style issue

Filter PMU events with raw format in i386 code.
For i386, raw format indicates that the PMU event code is already

Introduce a new vbootrom memory region. The region is mapped at address
"0x" and has a size of 128KB, identical to the SRAM region size.
This memory region is intended for loading a vbootrom image file as part of the
boot process.
The vbootrom region is initialized as ROM and registered in
