Hauke Mehrtens 6404b7cb83 MIPS: BCM47XX: use fallback sprom var for board_{rev,type}
An SoC normally do not define path variables for board_rev and
board_type and the Broadcom SDK also uses the nvram values without a
prefix in such cases. Do the same to fill these sprom attributes from
nvram and do not leave them empty, because brcmsmac do not like this.

Hauke Mehrtens 924ffb7dba MIPS: BCM47XX: trim the nvram values for parsing
Some nvram values on some devices have a newline character at the end
of the value, that caused read errors. Trim the string before reading
the number.

Hauke Mehrtens 111bd981e2 MIPS: BCM47XX: add bcm47xx prefix in front of nvram function names
The nvram functions are exported and used by some normal drivers. To
prevent name clashes with ofter parts of the kernel code add a bcm47xx_
prefix in front of the function names and the header file name.

Hauke Mehrtens ee7e2f3c23 MIPS: BCM47XX: use common error codes in nvram reads
Instead of using our own error codes use some common codes.

Ralf Baechle 7034228792 MIPS: Whitespace cleanup.
Having received another series of whitespace patches I decided to do this
once and for all rather than dealing with this kind of patches trickling
in forever.

Hauke Mehrtens b8ebbaff03 MIPS: BCM47xx: sprom: read values without prefix as fallback
There are bcma based devices like the Linksys E2000 out there, which do
have one ieee80211 core, but no PCIe core and they are using no
prefixes for the sprom. In addition some values like boardtype are
stored without a prefix for the main SoC chip also when they have an
additional PCIe wifi chip with an own boardtype var on some devices.

The Ethernet addresses are now also read out correctly without a prefix
so calling bcm47xx_fill_sprom_ethernet is not needed any more.

Hauke Mehrtens 5d24ceab4e MIPS: BCM47xx: read out full board data
Read out the full board data independently of the sprom version. Now we
also get the full boardflags and so on if sromrev is not set and our
code would assume a rev 1 device. When a nvram option is not set
because it is not there this is no problem.

Nathan Hintz 5fe2e0711d bcma: Move initialization of SPROM to prevent overwrite
The first thing bcm47xx_fill_sprom does is initialize (zero fill) the SPROM.  For
BCMA SOC, this wipes out any values previously read by bcm47xx_fill_sprom_ethernet
(see arch/mips/bcm47xx/setup.c - bcm47xx_get_sprom_bcma).  Move the initialization
of SPROM so it is called prior to filling in any values.

Hauke Mehrtens 019eee2e34 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.
