+ * @prtint: Host Port Interrupt (PrtInt)

+ * scheduled for the current microframe.
+ * Incomplete Isochronous OUT Transfer (incompISOOUT)
+ * The Device mode, the core sets this interrupt to indicate that

+ * in the current microframe. This interrupt is asserted along with
+ * the End of Periodic Frame Interrupt (EOPF) bit in this register.
+ * @oepint: OUT Endpoints Interrupt (OEPInt)
+ * The core sets this bit to indicate that an interrupt is pending on
+ * one of the OUT endpoints of the core (in Device mode). The
+ * application must read the Device All Endpoints Interrupt
+ * (DAINT) register to determine the exact number of the OUT
+ * endpoint on which the interrupt occurred, and then read the
+ * corresponding Device OUT Endpoint-n Interrupt (DOEPINTn)
+ * register to determine the exact cause of the interrupt. The
+ * application must clear the appropriate status bit in the
+ * corresponding DOEPINTn register to clear this bit.
+ * @iepint: IN Endpoints Interrupt (IEPInt)
+ * The core sets this bit to indicate that an interrupt is pending on
+ * one of the IN endpoints of the core (in Device mode). The
+ * application must read the Device All Endpoints Interrupt
+ * (DAINT) register to determine the exact number of the IN
+ * endpoint on which the interrupt occurred, and then read the
+ * corresponding Device IN Endpoint-n Interrupt (DIEPINTn)
+ * register to determine the exact cause of the interrupt. The
+ * application must clear the appropriate status bit in the
+ * corresponding DIEPINTn register to clear this bit.
+ * @epmis: Endpoint Mismatch Interrupt (EPMis)
+ * Indicates that an IN token has been received for a non-periodic
+ * endpoint, but the data for another endpoint is present in the top
+ * of the Non-Periodic Transmit FIFO and the IN endpoint
+ * mismatch count programmed by the application has expired.
+ * @eopf: End of Periodic Frame Interrupt (EOPF)

+ * @isooutdrop: Isochronous OUT Packet Dropped Interrupt (ISOOutDrop)
+ * The core sets this bit when it fails to write an isochronous OUT

+ * enough space to accommodate a maximum packet size packet
+ * for the isochronous OUT endpoint.
+ * @enumdone: Enumeration Done (EnumDone)
+ * The core sets this bit to indicate that speed enumeration is
+ * complete. The application must read the Device Status (DSTS)
+ * register to obtain the enumerated speed.
+ * @usbrst: USB Reset (USBRst)
+ * The core sets this bit to indicate that a reset is detected on the

+ * period of time.
+ * @erlysusp: Early Suspend (ErlySusp)

+ * This bit is always 0x0.
+ * @ulpickint: ULPI Carkit Interrupt (ULPICKINT)

+ * effect in the core. This bit can be cleared by writing the Clear
+ * Global OUT NAK bit in the Device Control register
+ * (DCTL.CGOUTNak).
+ * @ginnakeff: Global IN Non-Periodic NAK Effective (GINNakEff)
+ * Indicates that the Set Global Non-Periodic IN NAK bit in the
+ * Device Control register (DCTL.SGNPInNak), set by the
+ * application, has taken effect in the core. That is, the core has
+ * sampled the Global IN NAK bit set by the application. This bit
+ * can be cleared by clearing the Clear Global Non-Periodic IN
+ * NAK bit in the Device Control register (DCTL.CGNPInNak).
+ * This interrupt does not necessarily mean that a NAK handshake
+ * is sent out on the USB. The STALL bit takes precedence over
+ * the NAK bit.
+ * @nptxfemp: Non-Periodic TxFIFO Empty (NPTxFEmp)
+ * This interrupt is asserted when the Non-Periodic TxFIFO is
+ * either half or completely empty, and there is space for at least
+ * one entry to be written to the Non-Periodic Transmit Request
+ * Queue. The half or completely empty status is determined by
+ * the Non-Periodic TxFIFO Empty Level bit in the Core AHB
+ * Configuration register (GAHBCFG.NPTxFEmpLvl).
+ * @rxflvl: RxFIFO Non-Empty (RxFLvl)
+ * Indicates that there is at least one packet pending to be read
+ * from the RxFIFO.
+ * @sof: Start of (micro)Frame (Sof)
+ * In Host mode, the core sets this bit to indicate that an SOF
+ * (FS), micro-SOF (HS), or Keep-Alive (LS) is transmitted on the
+ * USB. The application must write a 1 to this bit to clear the
+ * interrupt.
+ * In Device mode, in the core sets this bit to indicate that an SOF
+ * token has been received on the USB. The application can read
+ * the Device Status register to get the current (micro)frame
+ * number. This interrupt is seen only when the core is operating
+ * at either HS or FS.
+ * @otgint: OTG Interrupt (OTGInt)
+ * The core sets this bit to indicate an OTG protocol event. The

There should be a few helper macros. I don't know the names for
these:
#define bid_to_xxx1(block_id) ((block_id) & 1) ? 0x100000000000ull : 0)
#define bid_to_xxx4(block_id) ((block_id) & 1) ? 0x40000000000ull : 0)
#define bid_to_xxx8(block_id) ((block_id) & 1) ? 0x8000000000ull : 0)
#define SEG_PREFIX 0x00016F001000ull << 15
#define CVMX_ADD(addr) CVMX_ADD_IO_SEG(SEG_PREFIX | (addr))
Then CVMX_USBCX_DAINTMSK() becomes:
#define CVMX_USBCX_DAINT(block_id) (CVMX_ADD(0x0818) + bid_to_xxx1(block_id))
It fits on one line and it uses words instead of magic numbers.
