| * arm: mvebu: turris_omnia: add RESET button handlingMarek Behún2019-05-031-0/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a Factory RESET button on the back side of the Turris Omnia router. When user presses this button before powering the device up and keeps it pressed, the microcontroller prevents the main CPU from booting and counts how long the RESET button is being pressed (and indicates this by lighting up front LEDs). The idea behind this is that the user can boot the device into several Factory RESET modes. This patch adds support for U-Boot to read into which Factory RESET mode the user booted the device. The value is an integer stored into the omnia_reset environment variable. It is 0 if the button was not pressed at all during power up, otherwise it is the number identifying the Factory RESET mode. This patch also changes bootcmd to a special hardcoded value if Factory RESET button was pressed during device powerup. This special bootcmd value sets the colors of all the LEDs on the front panel to green and then tries to load the rescue image from the SPI flash memory and boot it.

However, the old call to set up MII pin muxing was not removed. This may result in misconfiguration of the pin muxing for the BBE or duplicate configuration for other boards and so we remove this obsolete call.

Before the DM conversion only usdhc3 was enabled and therefore it appeared as MMC 0 to u-boot. After enabling MMC DM though usdhc3 defaults to MMC 2, which left unattended would drive changes to existing pico-pi bootscripts and environment variables that rely on mmc 0. Setup the alias of mmc0 and usdhc3 so that existing pico-imx7d boot code will work unmodified. When converting to DM_MMC it is necessary that SPL initializes eMMC by itself, so move the original eMMC initialization from U-Boot proper to SPL.

This watchdog servicing is enabled via CONFIG_WATCHDOG. Without this approach, new boards or platforms needed to implement a board specific version of this functionality, mostly copy'ing the same code over and over again into their board or platforms code base. With this new generic function, the scattered other functions are now removed to be replaced by the generic one. The new version also enables the configuration of the watchdog timeout via the DT "timeout-sec" property (if enabled via CONFIG_OF_CONTROL). This patch also adds a new flag to the GD flags, to flag that the watchdog is ready to use and adds the pointer to the watchdog device to the GD. This enables us to remove the global "watchdog_dev" variable, which was prone to cause problems because of its potentially very early use in watchdog_reset(), even before the BSS is cleared.
