For one of my devices I need to add a few entries to /dev for the
serial console. Currently there's a IMAGE_DEVICE_TABLE which gets set
to the files/device_table-minimal.txt found in the BBPATH.
I could create a new device table by copying the minimum and add the
entry I need, or I could modify the default. But it seems that it'd
be better to just accept multiple device tables and then I can list
both the minimal and the additional device tables. I can see several
other situations in which this would be useful.
The attached patch implements this.
Does anyone have any issues with this?
This allows me to just do:
IMAGE_DEVICE_TABLES = "files/device_table-minimal.txt
files/device_table-sci.txt"
where files/device_table-sci.txt contains:
# Include nodes for the SCI/SCIF serial ports on sh* boards
/dev/ttySC c 640 0 5 204 8 0 1
3
to get the SCI/SCIF serial ports added for my sh based devices.
I used a different variable IMAGE_DEVICE_TABLES which is only used if
the old IMAGE_DEVICE_TABLE is not definied. I also made it
automatically search in the BBPATH for the files since it's unlikley
you'd do anything else.
