2011-05-19MIPS: BCM47xx: Fix MAC address parsing.Hauke Mehrtens
Some devices like the Netgear WGT634u are using minuses between the blocks of the MAC address and other devices are using colons to separate them.

2010-12-16MIPS: BCM47xx: Use sscanf for parsing mac addressHauke Mehrtens
Instead of writing own function for parsing the mac address we now use sscanf.

2010-08-05MIPS: BCM47xx: Fix nvram_getenv return value.Hauke Mehrtens
Nvram_getenv should behave like cfe_getenv. cfe_getenv returns 0 on success and -9 if the value was not found. If the input was wrong -8 will be returned by cfe_getenv. Change nvram_getenv to do the same.

2010-07-05MIPS: BCM47xx: Add NVRAM support devicesWaldemar Brodkorb
When trying to netboot a Linksys WRT54GS WLAN router, the bootup fails, because of following error message: ... [ 0.424000] b44: b44.c:v2.0 [ 0.424000] b44: Invalid MAC address found in EEPROM [ 0.432000] b44 ssb0:1: Problem fetching invariants of chip,aborting [ 0.436000] b44: probe of ssb0:1 failed with error -22 ... The router uses a CFE bootloader, but most of the needed environment variables for network card initialization, are not available from CFE via printenv and even though not via cfe_getenv(). The required environment variables are saved in a special partition in flash memory. The attached patch implement nvram_getenv and enables bootup via NFS root on my router. Most of the patch is extracted from the OpenWrt subversion repository and stripped down and cleaned up to just fix this issue. [Ralf: sorted out header file inclusions. Lots of unneded headers and such that should have been included.] Signed-off-by: Waldemar Brodkorb <wbx@openadk.org> Reviewed-by: Phil Sutter <phil@nwl.cc> To: linux-mips@linux-mips.org Cc: Hauke Mehrtens <hauke@hauke-m.de> Patchwork: http://patchwork.linux-mips.org/patch/1359/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
