	This patch brings the lwmon5 board support up-to-date. Here a summary of the changes: lwmon5 board port related: - GPIO's changed to control the LSB transmitter - Reset USB PHY's upon power-up - Enable CAN upon power-up - USB init error workaround (errata CHIP_6) - EBC: Enable burstmode and modify the timings for the GDC memory - EBC: Speed up NOR flash timings lwmon5 board POST related: - Add FPGA memory test - Add GDC memory test - DSP POST reworked - SYSMON POST: Fix handling of negative temperatures - Add output for sysmon1 POST - HW-watchdog min. time test reworked Additionally some coding-style changes were done.
