Subject: [PATCH 6/6] sb: fix nvram_get on bcm47xx platform
|
|
|
|
The nvram_get function was never in the mainline kernel, it only
|
|
existed in an external OpenWrt patch. Use nvram_getenv function, which
|
|
is in mainline and use an include instead of an extra function
|
|
declaration.
|
|
et0macaddr contains the mac address in text from like
|
|
00:11:22:33:44:55. We have to parse it before adding it into macaddr.
|
|
|
|
nvram_parse_macaddr will be merged into asm/mach-bcm47xx/nvram.h though
|
|
the MIPS git tree and will be available soon. It will not build now
|
|
without nvram_parse_macaddr, but it haven't done before.
|
