This adds support for parsing sprom form nvram for sprom version form 1 to 9. It also adds sprom from nvram support for devices on the bcma bus. git-svn-id: svn://svn.openwrt.org/openwrt/trunk@30638 3c298f89-4303-0410-b956-a3cf2f4a3e73

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.
