[PATCH 0/3] wl12xx: improve firmware transfer efficiency

[Luciano Coelho <coelho@ti.com>]

Hello,

These patches increase the FW upload efficiency by using multiple SDIO
blocks in a single write.  After a lot of measurements, studies and
discussions, I came to the conclusion that 16K chunks is the optimal
size to use.  This reduces the upload time by a factor of 0.43 on
wl127x and by a factor of 0.17 on wl128x.  In absolute numbers this
means 75ms and 179ms respectively.

The first patch changes the semantics and name of the blocksize
alignment quirk to negative, to simplify the code in the next two
patches.

Cheers,
Luca.
