Pre-requisites: any MIPS board with ASCII-based NVRAM mapped into memory
1. Add "device nvram2env" into kernel configuration
2. Specify hints: base is mandatory (according to nvram2env(4))
hint.nvram.0.base=0x1c7f8000 (it's valid address for Asus RT-N53 with flags = 0x4)
3. Build & load kernel with bootverbose
Actual result: only part of nvram variables are found
Expected result: all variables are found
