/*
 * tpudrv12.c (TPU driver for RF type 12) is a required part of the L1
 * code for TI GSM chipset solutions consisting of Calypso or other
 * classic (non-LoCosto) DBB, one of the classic ABB chips such as Iota
 * or Syren, and Rita RF transceiver; the number 12 refers to the latter.
 *
 * We, the FreeCalypso team, have not been able to find an original
 * source for this C module: the LoCosto source has tpudrv61.c instead,
 * supporting LoCosto RF instead of Rita, whereas the TSM30 source
 * only supports non-TI RF transceivers.  Our only available reference
 * for what this tpudrv12.c module is supposed to contain is the
 * tpudrv12.obj COFF object from the Leonardo semi-src deliverable.
 *
 * The present reconstruction has been made by copying tpudrv61.c and
 * tweaking it to match the disassembly of the reference binary object
 * named above.
 *
 * The ugly hacks to support Compal and Pirelli targets in addition to
 * classic TI/Openmoko ones are original to FreeCalypso.
