libertas_cs: helper firmware doesn't answer

[Eugene Kozlov]

Hello
We are developing custom board on ep9307a soc with Marvell 88W8385 wifi
module.
I modify pcmcia driver for compatibility with cf interface and get cf
socket registered and can read CIS information.
I try to use libertas_cs 2.6.23-rc4 driver with 2.6.22 kernel and got a
problem with downloading firmware:
> libertas_cs: helper firmware doesn't answer
After helper firmware downloaded it read value 4 from register 20 but
can't read  value 10 from 28 register.

I add printf in if_cs_poll_while_fw_download function.
Attach here libertas debug libertas_debug.log and log from reading cis
libertas_cis.log information.

Thank for any advice. Marvell chip is closed so i actually can't find
any information about internal registers.

Also some logs from sysfs:
