ec759a2b38 [PATCH] bcm43xx: Fix PPC machine checks and match loopback gain specs
The specifications for loopback_gain calculation and for G PHY
initialization have been updated. This patch implements them and
fixes a machine check error that occurs for PPC architecture with a
phy->rev of 1.

83b5db89c8 [PATCH] bcm43xx: Fix machine check on PPC for version 1 PHY
Recent changes in the specs that were introduced in commit
740ac4fb08 were incorrect and resulted in machine check
errors on the PPC architecture for G PHY's with a revision number equal to 1. The
two offending changes are reverted.

a5d79d1e4f [PATCH] bcm43xx: OFDM fix for rev 1 cards
Nearly all of the writes to the bcm43xx internal lookup tables (ilt)
involve 16-bit quantities. Accordingly, the ilt_write routine was
coded to pass a u16 value. For one early GPHY chip, 32-bit quantities
are needed. For those writes, the value was clipped to 16 bits. This
patch adds an ilt_write32 routine that receives a 32-bit quantity
and writes it to the appropriate locations.

740ac4fb08 [PATCH] bcm43xx: Fix for 4311 and 02/07/07 specification changes
The specifications for the bcm43xx driver have been modified. This
patch incorporates these changes in the code, which results in the
BCM4311 and BCM4312 working. The name of one of the PHY parameters,
previously known as "version", has been changed to "analog", short for
"analog core version" .

a271ca5bbb [PATCH] bcm43xx-softmac: update PHY initialization
This patch updates the PHY initialization code for bcm43xx-softmac
to conform with recent changes in the clean-room specs at
http://bcm-specs.sipsolutions.net. Mostly, these changes implement
the sequence needed for chips with GPHY revision 8; however, the
patch also corrects a typo in one address, and some parts that were
missing from the spec when the initial coding was done.

2087da5dc1 [PATCH] bcm43xx: voluntary preemtion in the calibration loops
This patch adds voluntary preemption points into the
PHY calibration loops to allow non-CONFIG_PREEMPT machines
to not suffer from huge delays.
CONFIG_PREEMPT machines are already fine, because all this
code is run in non-atomic process context.

bcm43xx_phy_initg() to avoid a machine check on chips where they don't
