[Qemu-devel] [PATCH 0/7] MIPS Boston board support

[Paul Burton]

This series introduces support for the MIPS Boston development board. It begins
by introducing support for moving MIPS Coherence Manager GCRs which Boston
software typically does to avoid conflicting with its flash memory region. An
API is then added to retrieve the emulated MIPS GIC timer frequency, which is
used to report system clock frequency to software via "platform registers"
which the Boston board provides. An issue with the MIPS GIC that current Boston
Linux kernels encounter is fixed, and an API introduced to allow the board to
determine whether the MIPS CPS hardware is supported.

The last 3 patches are more extensive, providing support for the FIT image
format used with Boston, the Xilinx PCIe controller which Boston boards include
3 of, and finally the Boston board support itself.

This can be tested with either U-Boot or Linux if desired. U-Boot support is
available in the following patchset:

Linux kernel support will hopefully be submitted for v4.9, but an older version
of it can be found in the "eng" branch of:

  git://git.linux-mips.org/pub/scm/linux-mti.git

The vmlinux.gz.itb make target should be used when building a Linux kernel to
run on the Boston board.
