To finally fix this, this patch now moves the U-Boot size from 0x6.0000 to 0x8.0000, giving enough space for the next time. This also changes the environment location and potentially the MTD partitioning, but I see no better fix for now. Especially since this board does not have an active maintainer.

It has the following features - 512M DDR2 - 2 PCI connectors - 1 x1 PCI-e interface - 1 Gigabit Ethernet Port - 2 SATA Ports - USB 2.0 Interface - SDIO - 128M NAND Flash - 16M SPI Flash It can be strapped to boot from SPI or NAND so there are two defconfigs (one per boot media).

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.
