Hei hei,
while setting up U-Boot for a new board, I read doc/README.distro and tried to follow it for making things smooth with standard distributions. The document mentions the so called "Boot Loader Specification" [1] as follows:
This is roughly as specified at:
http://www.freedesktop.org/wiki/Specifications/BootLoaderSpec/
... with the exceptions that the BootLoaderSpec document:
I played with the extlinux.conf format snippets from the U-Boot docs. Upstream extlinux docs are not really helpful, especially not for options regarding dtb files. And I tried a config based on the Boot Loader Spec:
Scanning mmc 2:1... Found /boot/extlinux/extlinux.conf Retrieving file: /boot/extlinux/extlinux.conf 366 bytes read in 268 ms (1000 Bytes/s) Ignoring unknown command: title Ignoring unknown command: version Ignoring unknown command: options Ignoring unknown command: linux Ignoring unknown command: devicetree
Am I right, U-Boot does not support that spec at all? Files are in different positions, and the keywords are all different? If so, then the U-Boot documentation is misleading (and people will be frustrated to follow the hints given in there).
Are there any plans to support that specification or is anybody working on that? If not, would a patch be okay to reword that part of the documentation?
