Why is this necessary? The interrupts were enabled for all
architectures before.
My concern is with these lines:
write_ssi_mask(&ssi->sier, 0, CCSR_SSI_SIER_TDMAE);
...
write_ssi_mask(&ssi->sier, CCSR_SSI_SIER_TDMAE, 0);
This toggles the TDMAE interrupt on PowerPC, which I believe is VITAL to
making it work. The SSI and the DMA controller talk to each other
automatically, and if I'm reading the documentation correctly, that
communication depends on TDMAE and RDMAE.
