2020-07-17treewide: convert bd_t to struct bd_info by coccinelleMasahiro Yamada
The Linux coding style guide (Documentation/process/coding-style.rst) clearly says: It's a **mistake** to use typedef for structures and pointers. Besides, using typedef for structures is annoying when you try to make headers self-contained. Let's say you have the following function declaration in a header: void foo(bd_t *bd); This is not self-contained since bd_t is not defined. To tell the compiler what 'bd_t' is, you need to include <asm/u-boot.h> #include <asm/u-boot.h> void foo(bd_t *bd); Then, the include direcective pulls in more bloat needlessly. If you use 'struct bd_info' instead, it is enough to put a forward declaration as follows: struct bd_info; void foo(struct bd_info *bd); Right, typedef'ing bd_t is a mistake. I used coccinelle to generate this commit.

2020-07-09drivers: rename drivers to match compatible stringWalter Lozano
When using OF_PLATDATA, the bind process between devices and drivers is performed trying to match compatible string with driver names. However driver names are not strictly defined, and also there are different names used when declaring a driver with U_BOOT_DRIVER, the name of the symbol used in the linker list and the used in the struct driver_info. In order to make things a bit more clear, rename the drivers names. This will also help for further OF_PLATDATA improvements, such as checking for valid driver names.

2020-07-09x86: video: Support copy framebuffer with probed devicesSimon Glass
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. 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).
