2018-09-19phy: marvell: Support changing SERDES map in board fileMarek Behún
This adds a weak definition of comphy_update_map to comphy_core, which does nothing. If this function is defined elsewhere, for example in board file, the board file can change some parameters of SERDES configuration. This is needed on Turris Mox, where the SERDES speed on lane 1 has to be set differently when SFP module is connected and when Topaz Switch module is connected. This is a temporary solution. When the comphy driver for armada-3720 will be added to the kernel, the comphy driver in u-boot shall also be updated and this should be done differently then.

2018-09-19ARM: mach-mvebu: handle fall-back to UART bootChris Packham
The bootROM in the Armada-38x (and similar) SoC has two modes for UART boot. The first is when the normal boot media is blank (or otherwise missing the kwb header). The second is when the boot sequence has been interrupted with the magic byte sequence on the UART lines. In the first mode the bootROM routine and error code register will indicate that there was an error booting from the configured media in bits 7:0. In the second mode there is no error to indicate but the boot source is provided via bits 31:28. Handle both situations so that kwboot can be used for both boot strapping a blank board and for intercepting a regular boot sequence.

2018-09-19tools: kwboot: Make kwboot more robust on a38xJon Nettleton
This patch accomplishes 2 things to make the kwboot procedure on the a38x more reliable. 1) We fill the tty with 1K of the magic bootparam. This helps with the timing of where the microcode picks up in the read of the line to ensure we actually catch the break to go into recovery mode 2) Before starting the xmodem transfer we sleep for 2 seconds and then flush the line. This allows all the magic bootparam to be flushed from the line and makes the xmodem transfer reliable and removes the Bad message failures.

This API is going to be used to configure some pins that are protected for simple modification. It's not a comprehensive pinctrl driver but can be turned into one when we need this in the future. Now it is planned to be used only in one place. So that's why I decided not to pollute the codebase with a full-blown pinctrl-merrifield nobody will use. This driver reads corresponding fields in DT and configures pins accordingly. The "protected" flag is used to distinguish configuration of SCU-owned pins from the ordinary ones.
