[OpenWrt-Devel] [PATCH v2 2/3] ar71xx/image: allow builds of loader without cmdline injecting

Alexander Couzens lynxis at fe80.eu
Mon Mar 7 18:37:54 EST 2016


On most platforms the cmdline is supplied by the loader to the kernel.
When using an elf loader with cmdline the size is bloated by 512k.
For loader-elf platforms like the cpe510 better use loader-elf but patch
the cmdline into the kernel.

wdr1043: Tested loader still works using sysupgade image.
