barebox does not need the screen size directly, but we pass the
framebuffer to Linux via simnplefb it is desirable to pass the
full size of the framebuffer. Default to calculated values from
the screen resolution.

The IPU has a fractional pixelclock divider. When used, this produces
clock jitter which especially LVDS transceivers can't handle. Allow
to disable it via platform_data.

When requested 32bit formats the IPU generated a 24bit format instead.
Implement real 32bit format (xxrrggbb) and let the IPU generate a 24bit format
when requested.

No need to hardcode the channel parameters for the rgb offsets,
we can calculate them from the fb_bitfields. ipu_ch_param_write_field()
is the same as is the mainline IPUv3 driver.

bitfields are not portable and one should make assumptions of the
layout of bitfields. Replace them with the ipu_ch_param_write_field()
which is already used in the mainline IPUv3 driver.

With the IPU the way the display is connected is completely independent
of the framebuffer pixel format. So instead of specifying a pixel width
in platform_data we have to specify how the display is connected.

Before we jump to SDRAM where we just copied our code we have to

Do not call mtd_ioctl for mtdraw devices. mtd_ioctl will derefence
the priv pointer to a struct mtd_info whereas with mtdraw devices it will be
a struct mtdraw pointer. We do not need ioctls for mtdraw devices, so drop
it instead of fixing it.

A chdir to a path registered as an automount path followed by a 'ls'
results in an endless loop. This happens because the command the
automounter executes results in another automount request.
Fix this by running the automounter from the chdir code before
the cwd is actually changed.

We want to check whether boarddata contains a valid dtb if it's inside
valid memory. This includes the base of SDRAM, so use '>=' instead of '>'.

| ARM: omap4: Use writel where appropriate
