zd1211rw: timeout loading firmware in 2.6.29 on ARM (ep93xx)

zd1211rw: timeout loading firmware in 2.6.29 on ARM (ep93xx)

[David Huggins-Daines]

Hi,

I'm having trouble with two different zd1211 based cards on an 
ep93xx-based system using Linux 2.6.29.  Although the firmware is 
present and in the right place, loading it consistently fails with 
ETIMEDOUT.

I have the same problem with 2.6.27 and 2.6.28, as well as with the 
wireless-testing tree from a week ago.  dmesg (with debug enabled) says:
