// Notes for the following two ION vendor-specific param descriptors:
//
//      1.      These have a standard USB descriptor header so they look like a
//              normal descriptor.
//      2.      Any strings in the structures are in USB-defined string
//              descriptor format, so that they may be separately retrieved,
//              if necessary, with a minimum of work on the 930. This also
//              requires them to be in UNICODE format, which, for English at
//              least, simply means extending each __u8 into a __u16.
//      3.      For all fields, 00 means 'uninitialized'.
//      4.      All unused areas should be set to 00 for future expansion.
//

// This structure is ver 2 format. It contains ALL USB descriptors as
// well as the configuration parameters that were in the original V1
// structure. It is NOT modified when new boot code is downloaded; rather,
// these values are set or modified by manufacturing. It is located at
// xC00-xFBF (length 3C0h) in the ROM.
// This structure is a superset of the v1 structure and is arranged so
// that all of the v1 fields remain at the same address. We are just
// adding more room to the front of the structure to hold the descriptors.
//
// The actual contents of this structure are defined in a 930 assembly
// file, converted to a binary image, and then written by the serialization
// program. The C definition of this structure just defines a dummy
// area for general USB descriptors and the descriptor tables (the root
// descriptor starts at xC00). At the bottom of the structure are the
// fields inherited from the v1 structure.
