Detailed Description

Implementiation of a GICv2m MSI shim.

This shim adds MSI support to GICv2.

This should be instantiated with the appropriate number of frames, and SPI numbers thereof, to the system being modelled.

For example, in RealView.py (or whichever board setup is used), instantiate:

gicv2m = Gicv2m(frames=[ Gicv2mFrame(addr=0x12340000, spi_base=320, spi_len=64), Gicv2mFrame(addr=0x12350000, spi_base=100, spi_len=32), Gicv2mFrame(addr=0x12360000, spi_base=150, spi_len=16), Gicv2mFrame(addr=0x12370000, spi_base=190, spi_len=8), ])
