Reading the CFE properties causes system hangs on some devices. With this patch nvram read will be successful very time so cfe will no be read out. This code is not really correct but it will work around some problems for some people. Related ticket: #7693 git-svn-id: svn://svn.openwrt.org/openwrt/trunk@22663 3c298f89-4303-0410-b956-a3cf2f4a3e73

Subject: [PATCH 5/6] MIPS: BCM47xx: nvram_getenv fix return value.
|
|
|
|
nvram_getenv should behave like cfe_getenv. For now it is used like
|
|
cfe_getenv. cfe_getenv returns 0 on success and -1 in case of an error.
|
|
Change nvram_getenv to do the same.
