BD allocation and IDMA driver question

[kas turi]

Hi
 I would like to know what is the difference between
m8260_cpm_hostalloc and m8260_dp_alloc. The FCC driver
uses the former API and the serial driver uses the
latter API. When I try to use m8260_cpm_hostalloc to
allocate buffer descriptor for the SPI driver the
timesys 2.4 kernel hangs. When I use m8260_dp_alloc
the SPI driver works.
  Has anybody developed a IDMA driver for 8260 for 2.4
kernel?
  Thanks in advance.
