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.

When using a copy framebuffer we need to tell the video subsystem its
address. U-Boot's normally allocated framebuffer is used as the working
buffer, but nothing is displayed until it is copied to the copy
framebuffer.
For this to work the video driver must request that a framebuffer be
allocated separately from the hardware framebuffer, so add a check for
that.
Also add a log category so that logging appears correctly.

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
track of the buffer and add a function to do the copy.

The functions in this file do similar things but not always in the same
way. To make the code easier to read and compare, use a separate 'linenum'
variable in every function. This is then multiplied by the line length to
get the offset within the frame buffer to modify. Also use an 'x' variable
to hold the pixel position within that line. This is multipled by the
pixel size and added to the offset.
Also move the pbytes declaration up a little with the other long lines.
A side effect of splitting out these variables is that they are promoted
to int, i.e. a signed type, from the unsigned short used in the
vidconsole_priv struct. This would be necessary should any of the
variables go negative. At present this can actually happen in
console_putc_xy_2(), if the display width is not a multiple of the
character size (see next patch).

On a 4096bit key this comes down to to 257 uint32_t elements
in rr and 256 elements in rrtmp but with the current allocation
rr and rrtmp only have 129 uint32_t elements.
On 2048bit keys this works by chance as the defined max_rsa_size=4096
allocates a suitable number of elements, but with an actual 4096bit key
this results in other memory parts getting overwritten.
So as suggested by Heinrich Schuchardt just use the actual bit-size
