Subject: wl12xx: AP mode - init sequence

Split HW init sequence into AP/STA specific parts

The AP specific init sequence includes configuration of templates, rate
classes, power mode, etc. Also unmask AP specific events in the event mbox.

Separate the differences between AP and STA init into mode
specific functions called from wl1271_hw_init. The first is called after
radio configuration and the second after memory configuration.

From c8bde243421d759844264cf11e4248e7862c2722 Mon Sep 17 00:00:00 2001
From: Eliad Peller <eliad@wizery.com>
Date: Wed, 2 Feb 2011 09:59:35 +0200
Subject: wl12xx: move to new firmware (6.1.3.50.49)

This patch adds support for the new wl12xx firmware (Rev 6.1.3.50.49)

Since this fw is not backward compatible with previous fw versions,
a new fw (with different name) is being fetched.

(the patch is big because it contains all the required fw api changes.
splitting it into multiple patches will result in corrupted intermediate
commits)

Subject: wl12xx: change type from u8 to int

ret is used to store int types.  Using an u8 will break the error
handling.
