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).

This solves a compatibility issue with Linux device trees that contain TPMv2.x hardware. So it's easier to import DTS from upstream kernel when migrating board init from C code to DTS. The issue is that fallback binding is different between Linux and u-Boot. Linux: "tcg,tpm_tis-spi" U-Boot: "tis,tpm2-spi" As there are currently no in-tree users of the U-Boot binding, it makes sense to use Linux fallback binding.

2020-07-07net: smc911x: Properly handle EEPROM MAC addressAndre Przywara
When compiled as a DM_ETH driver, the scm911x driver was reading the MAC address from the optional EEPROM storage, but failed to copy this to the platdata struct. Since it was also missing a definition of the read_rom_hwaddr() function, the generic Ethernet code was dismissing this MAC address, falling back to a random address or denying to start at all. Add an implementation of .read_rom_hwaddr, and refactor the function reading the ROM address to be called by all interested parties. This fixes MAC address issues when using the driver in DM_ETH "mode".

2020-07-07gpio: search for gpio label if gpio is not found through bank nameHeiko Schocher
dm_gpio_lookup_name() searches for a gpio through the bank name. But we have also gpio labels, and it makes sense to search for a gpio also in the labels we have defined, if no gpio is found through the bank name definition. This is useful for example if you have a wp pin on different gpios on different board versions. If dm_gpio_lookup_name() searches also for the gpio labels, you can give the gpio an unique label name and search for this label, and do not need to differ between board revisions.

There maybe an overshoot: - when disabling, then re-enabling vrefbuf too quickly - or upon platform reset as external capacitor maybe slow discharging (VREFBUF is HiZ at reset by default). VREFBUF is used by ADC/DAC on some boards. An overshoot on the reference voltage make the conversions inaccurate for a short period of time. So: - Don't put the VREFBUF in HiZ when disabling, to force an active discharge. - Enforce a 1ms OFF/ON delay, also upon reset Penalty is a 1ms delay is applied (even for a cold boot), when enabling VREFBUF.
