Partition nodes without a compatible have no restrictions on additional properties. Fix this by ensuring 'unevaluatedProperties' is set when there's no compatible property. If there is a compatible property, then there should be a specific schema for it which will enforce 'unevaluatedProperties'.

title: TP-Link SafeLoader partitions
|
|
|
|
description: |
|
|
TP-Link home routers store various data on flash (e.g. bootloader,
|
|
flash layout, firmware, product info, configuration, calibration
|
|
data). That requires flash partitioning.
|
|
|
|
Flash space layout of TP-Link devices is stored on flash itself using
|
|
a custom ASCII-based format. That format was first found in TP-Link
|
|
devices with a custom SafeLoader bootloader. Later it was adapted to
|
|
CFE and U-Boot bootloaders.
|
|
|
|
Partitions specified in partitions table cover whole flash space. Some
|
|
contain static data that shouldn't get modified (device's MAC or WiFi
|
|
calibration data). Others are semi-static (like kernel). Finally some
|
|
partitions contain fully changeable content (like rootfs).
|
|
|
|
This binding describes partitioning method and defines offset of ASCII
|
|
based partitions table. That offset is picked at manufacturing process
|
|
and doesn't change.
