Marek Behún 539f0242f3 arm: mvebu: turris_omnia: add RESET button handling ... 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.
