[Buildroot] Building fw_printenv (u-boot utility) for target?

[Buildroot] Building fw_printenv (u-boot utility) for target?

[Grant Edwards]

I want fw_printenv on my target, and it would be convenient if
buildroot built it and set up the relvent links.  But, AFAICT, I can't
have buildroot build the fw_printenv utility without having it do a
complete build of U-Boot.  I don't have any need/desire for buildroot
to build the bootloader itself, I only need the fw_printenv linux app
for the target.  Is that possible with buildroot?

Or should I just build fw_printenv separately and stick it into the
filesystem using the custom package?

Currently not, is it a big deal to build u-boot as well?
The reason for this is mainly that fw_printenv isn't available
seperately, so we would need to double quite a lot of the u-boot
handling if we were to move it to a seperate package, and they are most
of the time used together.

That's naturally an option as well.

Mainly it's a hassle because it adds quite a bit to the build time.

Currently, I change my rootfs far more often than I change the U-Boot
sources or configuration.  Doing a U-Boot rebuild every time I change
my root filesystem wastes a lot of time.

That makes sense.

I guess I'll stick with that.

Thanks.
