1 /*
2 * tpudrv12.c (TPU driver for RF type 12) is a required part of the L1
3 * code for TI GSM chipset solutions consisting of Calypso or other
4 * classic (non-LoCosto) DBB, one of the classic ABB chips such as Iota
5 * or Syren, and Rita RF transceiver; the number 12 refers to the latter.
6 *
7 * We, the FreeCalypso team, have not been able to find an original
8 * source for this C module: the LoCosto source has tpudrv61.c instead,
9 * supporting LoCosto RF instead of Rita, whereas the TSM30 source
10 * only supports non-TI RF transceivers. Our only available reference
11 * for what this tpudrv12.c module is supposed to contain is the
12 * tpudrv12.obj COFF object from the Leonardo semi-src deliverable.
13 *
14 * The present reconstruction has been made by copying tpudrv61.c and
15 * tweaking it to match the disassembly of the reference binary object
16 * named above.
17 *
18 * The ugly hacks to support Compal and Pirelli targets in addition to
19 * classic TI/Openmoko ones are original to FreeCalypso.
