-/* Overview
- * ========
- *
- * _nomem_amba_init         - Init AMBA bus and calls _nomem_ambapp_find_buses
- * _nomem_ambapp_find_buses - Scan AMBA PnP info for AHB buses/bridges and
- *                            place them in i0-i5, see below
- * _nomem_find_apb          - Find one APB device identified by VENDOR:DEVICE
- *                            ID and an index.
- * _nomem_find_ahb          - Find one AHB Master or Slave device identified
- *                            by VENDOR:DEVICE ID and an index.
- * init_ahb_bridges         - Local function. Clears i0-i5
- * insert_ahb_bridge        - Local function. Insert a new AHB bus into first
- *                            free register in i0-i5. It also checks that the
- *                            bus has not already been added.
- * get_ahb_bridge           - Local function. Get AHB bus from registers,
- *                            return register iN, where N is defined by o0.
- *
- * The _nomem_find_apb and _nomem_find_ahb function requires that i0-i5
- * are populated with the AHB buses of the system. The registers are
- * initialized by _nomem_ambapp_find_buses.
- *
- * AHB Bus result and requirements of i0-i5
- * ========================================
- *
- * i0: AHB BUS0 IOAREA, no parent bus
- * i1: AHB BUS1 IOAREA, parent bus is always i0 (AHB BUS0) and bridge address
- * i2: AHB BUS2 IOAREA, 3-bit parent bus number and bridge address
- * i3: AHB BUS3 IOAREA, 3-bit parent bus number and bridge address
- * i4: AHB BUS4 IOAREA, 3-bit parent bus number and bridge address
- * i5: AHB BUS5 IOAREA, 3-bit parent bus number and bridge address
- *
- * AHB BUS
- * -------
- * Bits 31-20 (0xfff00000) contain the found bus I/O Area (AHB PnP area).
- *
- * 3-bit Parent bus
- * ----------------
- * Bits 2-0 (0x00000007) contain parent bus number. Zero if no parent
- * bus, 1 = parent is AHB BUS 0 (i0), 2 = parent is AHB BUS 1 (i1)..
- *
- * Bridge Address
- * --------------
- * Bits 10-5 (0x000007e0) contain the index of the Bridge's PnP
- * information on the parent. Since all bridges are found in the
- * PnP information they all have a PnP entry. Together with the
- * parent bus number the PnP entry can be found:
- *  PnPEntry = (BRIDGE_ADDRESS + (iN & 0xfff00000)) | 0x000ff800
- *  where N is the parent bus minus one.

-/**********************************************************************
- * How it works:
- * -------------
- * The framelist / Transfer descriptor / Queue Heads are similar like
- * in the linux usb_uhci.c.
- *
- * During initialization, the following skeleton is allocated in init_skel:
- *
- *         framespecific           |           common chain
- *
- * framelist[]
- * [  0 ]-----> TD ---------\
- * [  1 ]-----> TD ----------> TD ------> QH -------> QH -------> QH ---> NULL
- *   ...        TD ---------/
- * [1023]-----> TD --------/
- *
- *              ^^             ^^         ^^          ^^          ^^
- *              7 TDs for      1 TD for   Start of    Start of    End Chain
- *              INT (2-128ms)  1ms-INT    CTRL Chain  BULK Chain
- *
- *
- * Since this is a bootloader, the isochronous transfer descriptor have been removed.
- *
- * Interrupt Transfers.
- * --------------------
- * For Interrupt transfers USB_MAX_TEMP_INT_TD Transfer descriptor are available. They
- * will be inserted after the appropriate (depending the interval setting) skeleton TD.
- * If an interrupt has been detected the dev->irqhandler is called. The status and number
- * of transferred bytes is stored in dev->irq_status resp. dev->irq_act_len. If the
- * dev->irqhandler returns 0, the interrupt TD is removed and disabled. If an 1 is returned,
- * the interrupt TD will be reactivated.
- *
- * Control Transfers
- * -----------------
- * Control Transfers are issued by filling the tmp_td with the appropriate data and connect
- * them to the qh_cntrl queue header. Before other control/bulk transfers can be issued,
- * the programm has to wait for completion. This does not allows asynchronous data transfer.
- *
- * Bulk Transfers
- * --------------
- * Bulk Transfers are issued by filling the tmp_td with the appropriate data and connect
- * them to the qh_bulk queue header. Before other control/bulk transfers can be issued,
- * the programm has to wait for completion. This does not allows asynchronous data transfer.
