|
||||
Subject: [PATCH 1/3] ARM: dts: rename oxnas dts files
|
||||
|
||||
Other platforms' device-tree files start with a platform prefix, such as
|
||||
sun7i-a20-*.dts or at91-*.dts.
|
||||
This naming scheme turns out to be handy when using multi-platform build
|
||||
systems such as OpenWrt.
|
||||
Prepend oxnas files with their platform prefix to comply with the naming
|
||||
scheme already used for most other platforms.

Subject: [PATCH 67/69] generic: Mangle bootloader's kernel arguments
|
||||
|
||||
The command-line arguments provided by the boot loader will be
|
||||
appended to a new device tree property: bootloader-args.
|
||||
If there is a property "append-rootblock" in DT under /chosen
|
||||
and a root= option in bootloaders command line it will be parsed
|
||||
and added to DT bootargs with the form: <append-rootblock>XX.
|
||||
Only command line ATAG will be processed, the rest of the ATAGs
|
||||
sent by bootloader will be ignored.
|
||||
This is usefull in dual boot systems, to get the current root partition
|
||||
without afecting the rest of the system.

||||
