- Added iomux for CAN_STBY and RS484_TEN (GW52xx/GW53xx/GW54xx/GW551x) - Moved iomux of USBHUB_RST# out of board_ehci_hcd_init so that it is done regardless of USB being initialized in bootloader - Added usb_sel iomux/hwconfig for GW552x - Fixed mezzanine DIO for GW54xx - Fixed PANLEDR# for GW54xx - Fixed dio iomux/hwconfig for GW552x - Fixed dio iomux for GW551x - removed redundant #define Signed-off-by: Tim Harvey <tharvey@gateworks.com>
