I2S will get examined in more detail for the next kernel cycle. Our
multi-channel prototype I2S hardware is just about working. Once I get the
multi-channel hardware I will implement and heavily test a lot more I2S
capability.

count to estimate how far into the buffer DMA has
progressed. But that's not as accurate as just asking the DMA
hardware.
I poked around in the SRAM data and couldn't find the address. Is it
there or can the Bestcomm tasks be modified to leave it somewhere
visible?

I don't see where this gets enabled in the u-boot source. Have you
added it locally?
These are the only two I see:
cpu/mpc5xxx/cpu_init.c: *(vu_long *)(MPC5XXX_XLBARB + 0x40) |= (1 << 13);
cpu/mpc5xxx/cpu_init.c: *(vu_long *)(MPC5XXX_XLBARB + 0x40) |= (1 << 15);

Patch series to separate out the mpc5200 core DMA routines from
mpc5200_psc_i2s.c into a standalone mpc5200_dma.c. No intention
to change how anything works, this is just a code reorg needed for
later patches to build on.
