[PATCH 0/6] pxa: encode IRQ number into .nr_irqs (SPARSE IRQ)

[Eric Miao]

With the introduction of SPARSE_IRQ, the total number of IRQs (NR_IRQS)
can be made as a variable now. Conversion of most platforms looks to be
quite straight forward (as illustrated with the subsequent patches).
However, the platforms below select PXA_HAVE_BOARD_IRQS yet I feel hard
to find clues in the code if any of the board IRQs are used and how many.
Please advise:
