U-Boot either supports USB host or device mode for a node at a time in the device tree nodes. To support both host and dfu bootmodes, dr_mode is set to "peripheral" by default and then fixed based on the mode selected by the boot mode config dip switches on the board.
This needs to happen before the cdns3 generic layer binds the usb device to a host or a device driver. Therefore, use fdtdec_setup_board() implementation to fixup the device tree property.

AM64 EVM board has a micro USB 2.0 AB connector and the USB0_VBUS is connected with a resistor divider in between. USB0_DRVVBUS pin is muxed between USB0_DRVVBUS and GPIO1_79 signals.
Add the corresponding properties and set the pinmux mode for USB subsystem in the evm dts file.

For USB DFU boot mode there is a limitation on the load address of boot images that they have to be less than 0x70001000. Therefore, move the SPL_TEXT_BASE address to 0x70000000.
Currently ATF is being loaded at 0x70000000, if the SPL is being loaded at 0x70000000 then ATF would overwrite SPL image when loaded. Therefore, move the location of ATF to a latter location in SRAM, past the SPL image. Also rearrange the EEPROM and BSS data on top of ATF.
Given below is the placement of various data sections in SRAM

Due to a limitation for USB DFU boot mode, SPL load address has to be less than or equal to 0x70001000. So, load address of SPL and ATF have been moved to 0x70000000 and 0x701a0000 respectively.
Also, the maximum size of ATF has been increased to 0x1c000 [1].
Therefore, update ATF's location and maximum size accordingly in the device tree file.
