-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.

-
-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

-
-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.

-Subject: [PATCH 198/202] MIPS: BCM47XX: move and extend sprom parsing
-
-Move the sprom parsing from nvram into sprom.c. There are all values
-needed for sprom version 1 to 9 read from nvram and there are more
-sanity checks added. This is based on the sprom parsing in the open
-source part of the Broadcom SDK.

-Subject: [PATCH 199/202] MIPS: BCM47XX: provide sprom to bcma bus
-
-On SoCs the sprom is often stored in nvram in the flashchip. This patch
-registers a sprom fallback callback handler in bcma and provides the
-sprom needed for this device.
