Since the mdio code got upstreamed it is not possible
to activate network ports on CP110 Master and Slave.

The problem is in mvpp2_base_probe which is called for each
CP110 and it initializes the buffer area for descs and rx_buffers.

This should only happen once though and the bd space is actually
set to 0 after the first run of the function.

This leads to an error when the second CP110 tries the initialization
again and disables all network ports on this CP110.

This patch adds a static variable to check if the buffer area is
initialized only once globally.

x86: video: Support copy framebuffer with probed devices

For PCI video devices that are not mentioned in the devicetree, U-Boot
does not bind a driver before relocation, since PCI is not fully probed
at that point. Furthermore it is possible for the video device to be on
a secondary bus which is not even scanned.

This is fine if the framebuffer is allocated in fixed memory, as it
normally is on x86. But when using this as a copy framebuffer, we also
need U-Boot to allocate its own cached framebuffer for working in. Since
the video driver is never bound before relocation, the framebuffer size
is never set and U-Boot does no allocation.

Add a new CONFIG option to reserve 16MB of memory for this eventuality.
This allows vesa devices to use the copy framebuffer.

is allocated. This is not correct, since it should hold the bottom of the

video: Add support for copying to a hardware framebuffer

Some architectures use a cached framebuffer and flush the cache as needed
so that changes are visible. This is supported by U-Boot.

However x86 uses an uncached framebuffer with a 'write-combining' feature
to speed up writes.  Reads are permitted but they are extremely expensive.

Unfortunately, reading from the frame buffer is quite common, e.g. to
scroll it. This makes scrolling very slow.

Add a new feature which supports copying modified parts of the frame
buffer to the uncached hardware buffer. This speeds up scrolling by at
least 10x on x86 so the extra complexity cost seems worth it.

As a starting point, add the Kconfig, update the video structures to keep

Also move the pbytes declaration up a little with the other long lines.
