Based on hw/usb/hcd-ehci.c and hw/usb/hcd-ohci.c. Note that to use this with the dwc-otg driver in the Raspbian kernel, you must pass the option "dwc_otg.fiq_fsm_enable=0" on the kernel command line. Emulation of slave mode and of descriptor-DMA mode has not been implemented yet. These modes are seldom used. I have used some on-line sources of information while developing this emulation, including: http://www.capital-micro.com/PDF/CME-M7_Family_User_Guide_EN.pdf which has a pretty complete description of the controller starting on page 370. https://sourceforge.net/p/wive-ng/wive-ng-mt/ci/master/tree/docs/DataSheets/RT3050_5x_V2.0_081408_0902.pdf which has a description of the controller registers starting on page 130. Thanks to Felippe Mathieu-Daude for providing a cleaner method of implementing the memory regions for the controller registers.

On read, this register reads bits [27:0] of FPSCR plus the CONTROL.SFPA bit. On write, it doesn't just write back those bits -- it writes a value to the whole FPSCR, whose upper 4 bits are zeroes. We also incorrectly implemented the write-to-FPSCR as a simple store to vfp.xregs; this skips the "update the softfloat flags" part of the vfp_set_fpscr helper so the value would read back correctly but not actually take effect. Fix both of these things by doing a complete write to the FPSCR using the helper function.

U-Boot scans PHY at address 4/5/6/7 (see board_eth_init() in the U-Boot source: board/boundary/nitrogen6x/nitrogen6x.c). On the real board, the Ethernet PHY is at address 6. Adjust this by updating the "fec-phy-num" property of the fsl_imx6 SoC object. With this change, U-Boot sees the PHY but complains MAC address: Net: using phy at 6 FEC [PRIME] Error: FEC address not set. This is due to U-Boot tries to read the MAC address from the fuse, which QEMU does not have any valid content filled in. However this does not prevent the Ethernet from working in QEMU.
