Yes, the problem was due to missing dependent options..
I had incorrectly assumed that dependent options would get pulled in
or perhaps a error would be generated.
A warning can (and will) be generated for options that are
set by a BSP and don't end up in a final .config, but that's only
if you've placed them in a .cfg file and fed them through the
config auditing steps of the linux-yocto build (this is automatic).
dependencies won't be set automatically, it's the opposite,
you must ensure they are set or a particular Kconfig value must
select them.
It worked after I added following 3 options stated as dependent options
in a Kernel configuration database that I saw:
CONFIG_ISA
CONFIG_EISA
CONFIG_NET_PCI
I am still iterating to check if all three of the above are really needed or
or if just the CONFIG_NET_PCI option is needed.
I had enabled the option using a .cfg file. Also checking again to see if a warning
gets generated when the dependent options are not included.
BTW what does a message such as following in the .config file mean ?
"CONFIG_xxxxx is not set"
It should be:
# CONFIG_foo is not set
And that is should be read as "config foo is disabled"

I am unable to get the e100 driver to build for my BSP.
I have configured to build it as a module. I do not see the e100.ko
file being generated nor does
CONFIG_E100 appear in the generated .config file in my build area.
However I do see the driver source file e100.c in
tmp/work/bspname-poky-linux/linux-yocto-3.0.3+git1
+xxxx ../linux/drivers/net
I do not have any problems with other drivers (igb, E1000 etc) that I
have configured in exactly similar way.
Any insight on this issue ?
It's probably missing another option it depends on e.g. is
CONFIG_NET_PCI and CONFIG_MII enabled in your .config?
This is most likely what it is.
Out of curiosity, how did you enable the option ? Via a config fragement
(.cfg file) or via menuconfig .. or something else?
If you tried to set something via a fragment and it doesn't make it to
the final .config, you should see a warning during the kernel build
phase.
Cheers,
