[PATCH 0/2] pxa3xx: Data buffer dynamic allocation

[Ezequiel Garcia]

As part of my work to support the NAND controllers in Armada 370/XP SoC
here's a tiny set of patches to replace the currently data buffer allocation
based in a hardcoded buffer size, into a dynamic scheme.

We first use kmalloc to request a 256 bytes (big enough for the ONFI paramater
page) and then re-allocate (either with kmalloc or using DMA allocators) using
the detected page size.

The first patch is required to perform the initial NAND operations (READID
and friends) using programmable I/O since the DMA buffers are not ready
at such early stage.

The second patch performs to actual dynamic allocation and it's exactly
the same patch I sent a few weeks ago:

Daniel: Can you test these two If they look fine we can add them now,
being an improvement to the driver pxa3xx beyond the Armada 370/XP effort.

Thanks!
