arm, am335x: update for the siemens boards - dxr2: define unused pins as input - do not enable RTC32K OSC on dxr2 board - update default environment - add splashpos=m,m to default environment, so splash screen is always centered. - adapt environment for bootcount feature - add altbootcmd to default environment - rut: SPL add early reset pulse for eth-phy, maXTouch and display - rut: display timing aenderungen - siemens boards: adapt for background color = white - add boutcount feature for the siemens boards store the bootcount in the environment, as we have no softreset save registers on this hardware. Use therefore the CONFIG_BOOTCOUNT_ENV bootcount driver. - change spi mode from 3 to 0 for the lcd init - add gpio pin for lcd reset with state 0 and add mdelay - siemens boards: use own USB id's - add dfu serial and device number for siemens boards Add for the siemens boards the possibility to define in dfu mode, the iSerialNumber and the bcdDevice fields in the USB Device descriptor. - fix upgrade mechanism based on bootcount Correct location of saveenv and remove not active variable. Add CONFIG_BOOT_RETRY_TIME and CONFIG_RESET_TO_RETRY to reboot board in case of empty kernel partition. Without these defines an empty kernel partition leads to an abort of boot process and one remains in u-boot prompt. - general cleanup of dxr2, pxm2 and rut boards all: * Remove net boot from bootcmd Ping can cause a crash on boards without ethernet phy. net_nfs command is used only for development * Add reset at the end of bootcmd In order to have an immediate reset of the boot when bootcmd fails, add reset at the end of bootcmd. rut: * add nand_img_size dxr2: * update nand_img_size * ddr3 timings updated with iocontrol property that can be modified via eeprom.
