[Qemu-devel] [RFC 0/5] execute code from mmio area

[fred . konrad]

From: KONRAD Frederic <address@hidden>

This patch-set allows to execute code from mmio areas.
The main goal of this is to be able to run code for example from an SPI device.

The three first patch fixes the way get_page_addr_code fills the TLB.

The fourth patch implements the mmio execution helpers: the device must
implement the request_ptr callback of the MemoryRegion and will be notified when
the guest wants to execute code from it.

The fifth patch implements the execution from the SPI memories in the
xilinx_spips model.

Thanks,
Fred
