#     powerpc/powernv/ioda2: Reduce upper limit for DMA window size
#     
#     We use PHB in mode1 which uses bit 59 to select a correct DMA window.
#     However there is mode2 which uses bits 59:55 and allows up to 32 DMA
#     windows per a PE.
#     
#     Even though documentation does not clearly specify that, it seems that
#     the actual hardware does not support bits 59:55 even in mode1, in other
#     words we can create a window as big as 1<<58 but DMA simply won't work.
#     
#     This reduces the upper limit from 59 to 55 bits to let the userspace know
#     about the hardware limits.
#     
#     Fixes: 7aafac11e3 "powerpc/powernv/ioda2: Gracefully fail if too many TCE levels requested"
