+ * 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.
