2020-07-09video: Clear the copy framebuffer when clearing the screenSimon Glass
Update video_clear() to also sync to the copy framebuffer. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Anatolij Gustschin <agust@denx.de> Tested-by: Bin Meng <bmeng.cn@gmail.com>

2020-07-09video: Add support for copying to a hardware framebufferSimon Glass
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.

2020-07-09video: Adjust rotated console to start at right edgeSimon Glass
At present when the console is rotated 180 degrees it starts almost a whole character to the left of the right edge (typically 7 pixels with an 8-pixel-wide font). On a display which aligns with the font width, this just wastes space. On a display that does not this can result in x_frac going negative for the final character (the one on the left side) and the overflow -EAGAIN check at the start of the function failing. Change the function to start at the rightmost pixel to fix these problems.

2020-07-09video: Split out expression parts into variablesSimon Glass
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).

2020-05-17efi_loader: round the memory area in efi_add_memory_map()Michael Walle
Virtually all callers of this function do the rounding on their own. Some do it right, some don't. Instead of doing this in each caller, do the rounding in efi_add_memory_map(). Change the size parameter to bytes instead of pages and remove aligning and size calculation in all callers. There is no more need to make the original efi_add_memory_map() (which takes pages as size) available outside the module. Thus rename it to efi_add_memory_map_pg() and make it static to prevent further misuse outside the module. Signed-off-by: Michael Walle <michael@walle.cc> Add missing comma in sunxi_display.c.
