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.

USB Mass Storage Devices sometimes have the RMB (removable) bit set in
the SCSI INQUIRY response. Thumbdrives tend to have the bit set whereas
hard disks do not.
Operating systems differentiate between removable devices and fixed
devices. Under Linux, the anaconda installer looks for removable
devices. Under Windows, only fixed devices may have more than one
partition and AutoRun is also affected by the removable bit.
For these reasons, allow USB Mass Storage Devices to override the
removable bit:
qemu -usb
-drive if=none,file=test.img,cache=none,id=disk0
-device usb-storage,drive=disk0,removable=on
The default is off.

Provide the "removable" qdev property bit to override the SCSI INQUIRY
removable (RMB) bit for non-CDROM devices. This will be used by USB
Mass Storage Devices, which sometimes have this guest-visible bit set
and sometimes do not. They therefore requires a means for user
configuration.

Merge ide_dma_submit_check into it's only caller. Also use tail recursion
using a goto instead of a real recursion - this avoid overflowing the
stack in the pathological situation of an recurring error that is ignored.
We'll still be busy looping in ide_dma_cb, but at least won't eat up
all stack space after this.

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

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.
