Leon3 is an open-source VHDL System-On-Chip, well known in space industry (more
information on http://www.gaisler.com).

Leon3 is made of multiple components available in the GrLib VHDL library.
Three devices are implemented: uart, timers and IRQ manager.
You can find code for these peripherals in the grlib_* files.

Due to signed/unsigned comparison, the dirty bits are never reset, and
the screen redrawn each time. Fix that by only using ram_addr_t types,
and looking for page_min != addr_max instead.

isa_mem_base is computed from registers during reset, but due to QEMU
limitations some devices (e.g. VGA card) need to know it earlier when
they are registered.

Workaround this by setting the value during registration instead of
reset.

The PL190 implementation keeps the default vector address
in vect_addr[16], but we weren't using this for writes to
the DEFVECTADDR register. As a result of this fix the
default_addr structure member is unused and we can delete it.

Some tests in FPU emulation code were wrongly using float64_is_nan()
before commit 18569871, and wrongly
using float64_is_quiet_nan() after. Fix them by using float64_is_any_nan()
instead.

The current FPU code returns 0.0 if one of the operand is a
signaling NaN and the VXSNAN exception is disabled.

fload_invalid_op_excp() doesn't return a qNaN in case of a VXSNAN
exception as the operand should be propagated instead of a new
qNaN to be generated. Fix that by calling fload_invalid_op_excp()
only for the exception generation (if enabled), and use the softfloat
code to correctly compute the result.

deassert intx on device reset.
So far pci_device_reset() is used for system reset.
In that case, interrupt controller is reset at the same time so that
all irq is are deasserted.
But now pci bus reset/flr is supported, and in that case irq needs to be
disabled explicitly.
