build: remove vermagic hack
As the Gluon kernel won't be compatible with the OpenWrt upstream anymore, we don't need the vermagic hack anymore.

@ -76,21 +76,9 @@ A directory for the new target must be created under ``targets``, and it must be
|
|||
to ``targets/targets.mk``. In the new target directory, the following files must be created:
|
||||
|
||||
* profiles.mk
|
||||
* vermagic
|
||||
* config (optional)
|
||||
|
||||
For ``profiles.mk``, see :ref:`hardware-adding-profiles`.
|
||||
The file ``config`` can be used to add additional, target-specific options to the OpenWrt config.
|
||||
|
||||
The files ``vermagic`` must have the correct content so kernel modules from the upstream repositories
|
||||
can be installed without dependency issues. The OpenWrt version a Gluon release is based on is defined by the upstream package repo URL in ``include/gluon.mk``
|
||||
(in the variable ``DEFAULT_OPKG_REPO``); at the time this documentation was written, this was ``barrier_breaker/14.07``; whenever
|
||||
the package repo is updated, all ``vermagic`` files must be updated as well. The command ``make update-vermagic`` can be used to get the correct
|
||||
vermagic, or update the values when ``DEFAULT_OPKG_REPO`` has changed.
|
||||
|
||||
The content is a hash which is part of the version number of the kernel package. So in the case of ``ar71xx-generic`` on
|
||||
``barrier_breaker``, we look for the kernel package in the directory ``https://downloads.openwrt.org/barrier_breaker/14.07/ar71xx/generic/packages/base/``.
|
||||
As the kernel package is called ``kernel_3.10.49-1-0114c71ed85677c9c1e4911437af4743_ar71xx.ipk``, the correct ``vermagic`` string
|
||||
is ``0114c71ed85677c9c1e4911437af4743``.
|
||||
|
||||
After this, is should be sufficient to call ``make GLUON_TARGET=<target>`` to build the images for the new target.
