Subject: [PATCH 190/202] ssb: sprom fix some sizes / signedness
Some parts of the sprom struct are bigger than needed.
The leddc and maxpwr values are just 8 bit long and not 16.
rxpo2g and rxpo5g are signed
antenna_gain is unsigned
I got these information for the open source part of the Braodcom SDK
covering sprom version 1 to 9. rxpo2g contained a negative number on my
bcm5354 based device, this cased an error and Broadcom SDK says this is
signed.
I was unable to find any reverences to antenna_gain.ghz5 in the
Broadcom SDK.

Subject: [PATCH 191/202] ssb: fix per path sprom vars
On sprom version 4 and 5 there are 4 values for pa_2g, pa_5gl, pa_5g
and pa_5gh, for sprom version 8 and 9 there are only 3. Make the per
path sprom store also work for older sprom versions.

Subject: [PATCH 195/202] bcma: add support for sprom not found on the device.
On SoCs the sprom is stored in the nvram in a special partition on the
flash chip. The nvram contains the sprom for the main bus, but
sometimes also for a pci devices using bcma. This patch makes it
possible for the arch code to register a function to fetch the needed
sprom from the nvram and provide it to the bcma code.
