Move leds and sched_clock build conditionals out of the Makefile into
the Kconfig file.  Move selection of HAVE_SCHED_CLOCK into the

420c34e4cc ARM: add versatile family consolidated CLCD support
This consolidates the CLCD panel definitions and memory allocation into
one location.

Rename the Sanyo 2.5in and Epson 2.2in displays after their respective
part numbers.  Rather than using a general "Sanyo 2.5in" and "Epson
2.2in" description of the display panel, use the manufacturers part
number to be more specific.  This helps people identify what the timings
actually refer to, which are panel specific.

While here, add CLCD capability information to each panel definition,
which has no effect until we add the board-level capabilities.

7b4e9ced69 ARM: clcd: add method for describing display capabilities
The ARM CLCD PL110 controller in TFT mode provides two output formats
based on whether the controller is in 24bpp mode or not - either 5551
or 888.  PL111 augments this with a 444 and 565 modes.

Some implementations provide an external MUX on the PL110 output to
reassign the bits to achieve 565 mode.

Provide a system of capability flags to allow the CLCD driver to work
out what is supported by each panel and board, and therefore which
display formats are permitted.

e6b9c1f8a6 ARM: integrator: support CLCD RGB5551 layout for 16bpp
When the CLCD is in anything but RGB888 mode, its outputs are configured
for RGB5551 output.  Integrator/CP supports RGB565 via an external
multiplexer, which we configure for RGB5551 or RGB565 based only on the
bits per pixel.  So when userspace asks for the RGB555 layout, the mux
remains in RGB565 mode, and we produce incorrect colours.  Fix this.

Note that Integrator doesn't support BGR565 mode, but does support
BGR5551.

baaece2245 ARM: 6635/2: Configure reference clock for Versatile Express timers
Timers on Versatile Express mainboard are used as system clock/event
sources. Driver assumes that they are clocked with 1MHz signal.
Old V2M firmware apparently configured it by default, but on newer
boards one can observe that "sleep 1" command takes over 30 seconds
to finish, as the timers are fed with 32kHz instead...

This patch performs required magic and also removes code clearing
timer's control registers, as exactly the same operations are
performed by the timer driver few jiffies later.

d2a1c9ad78 ARM: realview: name configuration options after actual board names
As no one seems to really know which configuration options tie up with
which boards, I thought I'd do some investigation and try to work it
out.  After discussion with some folk in linaro, I think I have this
nailed.

The names are updated to use the name on the front of the appropriate
board user guide for the various baseboards, which I've taken to be
the official name for each board.

I haven't significantly updated the descriptions for the tiles as that
is even less clear - as far as I can see on ARMs website, there is no
Cortex-A9 tile for Realview EB - only ARM11MPCore, ARM1156T2F-S,
ARM1176TZF-S and Cortex-R4F.  So exactly what this 'Multicore Cortex-A9
Tile' is...

The function write_pen_release() references

This is often because write_pen_release lacks a __cpuinitdata

and trying to boot a DomU with 615MB of memory, the following crash was
observed in the dump:

kernel direct mapping tables up to 26f00000 @ 1ec4000-1fff000
BUG: unable to handle kernel NULL pointer dereference at (null)
IP: [<c0107397>] xen_set_pte+0x27/0x60
*pdpt = 0000000000000000 *pde = 0000000000000000

Adding further debug statements showed that when trying to set up
pfn=0x26700 the returned mapping was invalid.

pfn=0x266ff calling set_pte(0xc1fe77f8, 0x6b3003)
pfn=0x26700 calling set_pte(0xc1fe7800, 0x3)

Although the last_pfn obtained from the startup info is 0x26700, which
should in turn not be hit, the additional 8MB which are added as extra
memory normally seem to be ok. This lead to looking into the initial
p2m tree construction, which uses the smaller value and assuming that
there is other code handling the extra memory.

When the p2m tree is set up, the leaves are directly pointed to the
array which the domain builder set up. But if the mapping is not on a
boundary that fits into one p2m page, this will result in the last leaf
being only partially valid. And as the invalid entries are not
initialized in that case, things go badly wrong.

I am trying to fix that by checking whether the current leaf is a
complete map and if not, allocate a completely new page and copy only
the valid pointers there. This may not be the most efficient or elegant
solution, but at least it seems to allow me booting DomUs with memory
assignments all over the range.
