- 18-24v passive POE (mode B) on Ethernet 2
The tool ap51-flash (https://github.com/ap51-flash/ap51-flash) should be
used to transfer the factory image to the u-boot when the device boots up.

# The U-Boot loader of the OpenMesh devices requires image sizes and |

# The OpenMesh devices come with 2 main partitions - while one is active |
||||
# sysupgrade will flash the other. The boot order is changed to boot the |
||||
# newly flashed partition. If the new partition can't be booted due to |
||||
# upgrade failures the previously used partition is loaded. |

# 1. check what is the mtd index for the first flash region on this |

# 2. check if the target partition ("inactive") has the mtd index of |
||||
# the first flash region |
||||
# |
||||
# - when it is: the new bootseq will be 1,2 and the first region is |
||||
# modified |
||||
# - when it isnt: bootseq will be 2,1 and the second region is |
||||
# modified |
||||
# |
||||
# The detection has to be done via the hardcoded mtd partition because |
||||
# the current boot might be done with the fallback region. Let us |
||||
# assume that the current bootseq is 1,2. The bootloader detected that |
||||
# the image in flash region 1 is corrupt and thus switches to flash |
||||
# region 2. The bootseq in the u-boot-env is now still the same and |
||||
# the sysupgrade code can now only rely on the actual mtd indexes and |
||||
# not the bootseq variable to detect the currently booted flash |
||||
# region/image. |
||||
# |
||||
# In the above example, an implementation which uses bootseq ("1,2") to |
||||
# detect the currently booted image would assume that region 1 is booted |
||||
# and then overwrite the variables for the wrong flash region (aka the |
||||
# one which isn't modified). This could result in a device which doesn't |
