Do not use the base address to access data in local memory. This is in
preparation to allow chip connected via PCI where base address depends
on where the BAR is mapped so it will be unknown.

We only emulate the sysbus device in its default LE mode and PCI is LE
as well so specify this for registers. Colors were also off on both
SH4 and PPC which is also fixed here.

This says "the pixel in the framebuffer is little endian. If
the guest CPU is bigendian then the pixel format is RGB565;
otherwise it's BGR565". (This difference isn't a simple
endianness thing because the G pixel crosses the boundary
between two bytes.)
In the Linux kernel driver source, these two formats
correspond to "SWAP_FB_ENDIAN set" (BGR565) and not set
(RGB565), and the swap flag is set for BE PCI and for
(LE) embedded sh. I'm not convinced by that code though,
because the comment claims it's for handling an IO layer
swap that makes the PCI bus little endian, but that can't
make RGB565 turn into BGR565. See also kernel commit
fedbb3625b3c1644 which also says that code is wrong.
So I would not trust the kernel driver as a guide to the
right behaviour for 16 bit formats: it is clearly buggy.

This says "the pixel in the framebuffer is 32-bits always
little endian. If the guest CPU is bigendian then the
pixel format is XBGR; otherwise it's RGBX".
This is also saying the hardware behaves differently
for big and little endian guest CPUs, but in a different
way from 16 bit (both in whether big or little gets
the RGB order and in whether the other order is a
straight "all the fields in reverse order" or not).
That seems even less likely.
In the Linux kernel, "SWAP_FB_ENDIAN" flag set gets
us BGRX; not set gets us XRGB.
I think the correct behaviour here is for 16 bits:
rgb565 = lduw_le_p(s);
r = (rgb565 >> 8) & 0xf8;
g = (rgb565 >> 3) & 0xfc;
b = (rgb565 << 3) & 0xf8;
ie "always LE framebuffer, RGB565"
and for 32 bits:
r = s[2];
g = s[1];
b = s[0];
ie "always LE framebuffer, XRGB8888".
That makes sense, and it matches what the hardware
claims it does. I would recommend implementing that, unless
it doesn't work for some bit of guest software that you can
100% guarantee does display correctly on real hardware.
If it doesn't work on a particular bit of guest software
then that is quite likely guest software error
because nobody really thoroughly tested the driver
code a decade ago and nobody has the hardware now
to test the driver against.
The sm501 x.org driver appears to have been independently
implemented, so might be an interesting thing to test.
(Yes, trying to sort out a model of ancient hardware so it's
accurate sucks. If you can find a real copy of the hardware
so you can cross-check what it really does that's about
the only way to be sure about things.)
thanks

Adding vmstate saving is not in this patch because the state structure
will be changed in further patches, then another patch will add
vmstate descriptor after those changes.

v2: Add memory regions to device state instead of allocating them
v3: Added reset function and make sure to use adjusted mem size when
creating local mem region (also print a warning when mem size was
adjusted)
v4: Replace warning for corrected memory size with a hard error

This is not used by default on any emulated machine yet but it is
still useful to have it compiled so it can be added from the command
line for clients that can use it (e.g. MorphOS has no driver for any
other emulated video cards but can output via SM501)

Rework HWC handling to simplify it and fix cursor not updating on
screen as needed. Previously cursor was not updated because checking
for changes in a line overrode the update flag set for the cursor but
fixing this is not enough because the cursor should also be updated if
its shape or location changes. Introduce hwc_invalidate() function to
handle that similar to other display controller models.

This is to allow clients to initialise these without failing as long
as no 2D engine function is called that would use the written value.
Saved values are not used yet (may get used when more of 2D engine is
added sometimes) and clients normally only write to most of these
registers, nothing is known to ever read them but they are documented
as read/write so also implement read for these.

v2: Fixed mask of video_control register for a read only bit
Changed IRQ status register to write ignored as IRQ is not implemented
v3: Squashed read implementation into this patch
v4: Add reset for all 2D engine registers (although these are
documented to be 0 on reset, a comment in U-Boot source suggests that
they are really undefined so the previous version might have been enough)
