Browse Source 
Tis patch is to fix up some descriptions in README.
Per-device rootfs had been supported, and a known issue
had been found. These also should be updated accordingly.

4. Known issues and limitation
------------------------------
* u-boot may fail to read MAC addresses from EEPROM on some boards and there
won't be MAC addresses set in environment. This may cause kernel fails to
probe these network interfaces. The workaround is to set MAC addresses
manually, for example,
=> setenv ethaddr 00:04:9F:04:65:4b
=> setenv eth1addr 00:04:9F:04:65:4c
