-commit 121915c4ee0812a14bc8d752bc210d0238d755c1

- MIPS: BCM47xx: Add NVRAM support devices
-
- 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.]
