#     powerpc: enable a 30-bit ZONE_DMA for 32-bit pmac
#     
#     With the strict dma mask checking introduced with the switch to
#     the generic DMA direct code common wifi chips on 32-bit powerbooks
#     stopped working.  Add a 30-bit ZONE_DMA to the 32-bit pmac builds
#     to allow them to reliably allocate dma coherent memory.
#     
#     Fixes: 65a21b71f948 ("powerpc/dma: remove dma_nommu_dma_supported")
