9f92ecf761 Fix the remapping of the screen frame buffer. 
The size of the region to be mapped is determined by the buffer stride,
not the pixel width.

84a54ca083 uhci: use multiple TDs for data transfers larger than the max packet size. 
Unlike the other USB controllers, a UHCI transfer descriptor can only
request a single packet.

4c55182cd0 Disable UHCI legacy support and make sure all UHCI registers are initialised. 
The controller reset should set the USBINTR, FRNUM, and SOF registers to
their default values, but set them explicitly just to be sure.

08bbac1065 uhci: reset the queue head after handling a keyboard interrupt. 
When an interrupt transfer completes, the UHCI loads the QELP in the
QH with the link pointer from the TD (which is a null pointer in this
case). We need to set the QELP back to point at the TD to enable the
next interrupt transfer.

6cfb7e7e83 Miscellaneous fixes to the UHCI driver. 
This gets us to the point that a keyboard is detected when running
QEMU with a EHCI/UHCI combination controller and the first keypress
is detected and returned.

2c33aa3e85 Check for correct address space in probe_usb_controller() (issue #36). 
We expect UHCI controllers to be mapped into I/O space and the other
controller types to be mapped into Memory space. Print a diagnostic
message and abort if this is not the case. Only call map_region()
for controllers mapped into Memory space.

95c49848c8 Use the PRC status bit to detect when an XHCI port reset is complete (issue #31). 
Some controllers do not set the PR status bit immediately after it's written,
so polling that to detect when the reset is complete is unsafe.

Martin Whitaker
c13bb30893 Fix mapping of MADT (issue #29) 
We need to pass the physical address of the MADT to parse_madt(), not the
virtual address of the table signature, because parse_madt() needs to call
map_region() again to ensure the full table is mapped into virtual memory.

e0d42db07c Optimize the code by declaring several functions static in system/ehci.c.

b609c4dd81 Make detection of EHCI asynchronous transfer complete more robust. 
Using Interrupt On Completion is not robust, because the interrupt flag
is also set if a short transfer is detected. So we need to poll the
Active flag in the transfer descriptors.

5e2ab9289b Make sure the XHCI private memory is accessible. 
The XHCI device index and scratchpad buffers are mapped into high memory,
in order to conserve low memory. They need to be accessible in the virtual
address space to allow us to initialise them. After initialisation. only
the XHCI accesses them.

We also only need to access the data structures in the device private
workspace during initialisation, but keeping separate physical and virtual
addresses for these structures makes the code considerably more complex,
so for now, move these to low memory.

4078b7760e Faster barrier implementation. 
The old barrier implementation was very slow when running on a multi-socket
machine (pcmemtest issue 16).

The new implementation provides two options:

  - when blocked, spin on a thread-local flag
  - when blocked, execute a HLT instruction and wait for a NMI

The first option might be faster, but we need to measure it to find out. A
new boot command line option is provided to select between the two, with a
third setting that uses a mixture of the two.

9fca23105a Don't search for the RDSP at bootparams.acpi_rsdp_addr. 
This field is only used internally by the Linux kernel, so will always
be zero when bootparams is passed to us by a bootloader.

da7829d4c3 Ensure the ACPI tables and local APIC are mapped into an accessible region. 
We only map the first 4GB of physical address space, so if the ACPI tables
or local APIC are located above 4GB, or are overlaid when we remap something
else (e.g. the video frame buffer), we need to map them to somewhere we can
access. The ACPI tables are only used during startup, but the local APIC
will be needed when we are running tests if we are saving power by halting
idle CPU cores and using a NMI to wake them up.

5211b67e6c Add option to map_region to indicate we only use the region during startup.

e4ad2dfa1b Don't use the top 0.5GB of the 32-bit address space for device mapping. 
This region is commonly used by the BIOS for mapping hardware devices,

6b570cd779 Reduce the maximum mapped size of the linear frame buffer. 
This is needed for subsequent changes. If we do ever get presented with
a frame buffer larger than 8192x8192 pixels, we'll need to think again
about how to manage it.

f109a5814b Implement EHCI handover to companion controllers. 
Low/full speed USB devices attached directly to the root hub must be
rerouted to a companion controller. We can't rely on the BIOS to do
this for us. This requires us to initialise the EHCI device before
initialising any of its companions.

This also allows us to support keyboards attached via a high speed
hub on a system with EHCI plus companions.

dcac527068 Don't make assumptions about usable memory. 
When using a legacy BIOS, the memory regions used by the BIOS are well
defined. This is not the case when using a UEFI BIOS. So include the
stack area in the BSS so the loader knows how much memory to allocate,
and check we have space to relocate the program to either low or high
memory.

There are still some assumptions in the USB driver code that need to
be fixed.
