RFC: Renaming uboot-utils

RFC: Renaming uboot-utils

[Andy Wilcox]

Since uboot-utils builds a native binary (mkImage) it should really be 
called
uboot-utils-native.

My motivation is (a) I'd really like to build a few tools from uboot
which are cross-compiled (notably, fw-setenv/printenv, which allow R/W
access to the u-boot configuration space), and (b) it's the "right"
thing to do (-;

The following files would be updated:

./conf/distro/foonas.conf
./conf/distro/include/angstrom-2007-preferred-versions.inc
./packages/linux/em-x270_2.6.23.bb
./packages/linux/linux-bd-neon-2.6_2.6.22.bb
./packages/linux/linux-gumstix_2.6.15.bb

./packages/linux/linux-storcenter_2.6.12.6.bb
./packages/linux/linux-turbostation_2.6.20.2.bb
./packages/tasks/task-base.bb

Any objection or comment?

Thanks!
Andy

That part makes sense. FWIW, we already have a uboot-mkimage-native
recipe in OE.

And now you're talking about uboot-utils-cross, not uboot-utils-native

Also, consider u-boot-utils instead of uboot-utils. The project is
called u-boot and I thought I saw both namespaces appear in the u-boot
dir?
(If I'm too late, probably forget this).

Also +1 from me.

Not necessarely.

Anything *-cross is a tool that is built for, and runs on one platform
and generates output for another.

Andy said a few tools which *are* cross-compiled, so he I think he
wants to cross-compile tools, which are deployed on the target and as
such do not generate output for another target.

u-boot-utils-cross would be a package that generates tools, of which
the output only can run on a target.

I think some of the tools in u-boot are cross tools, some are not, and
some are agnostic (the output from mkimage can be interpreted on any
host AFAIK).

Regards,

Leon.

Leon is exactly right.  I meant I'd use the newly-freed u-boot-utils
to build a few programs for the target - in my case, I'm interested
in fw-setenv, which allows one command-line manipulation of the
u-boot environment area in flash.

Sorry for any confusion.

  Yeah, all this discussion became rather confusing. To understand
what's it all about, a careful look at the commit was required, and
that uncovered few botched things:

--- packages/uboot/u-boot-utils_1.2.0.bb        64396fa43c9fcef1ed1cd3ae82a49d140febbbd0
+++ packages/uboot/u-boot-utils_1.2.0.bb        64396fa43c9fcef1ed1cd3ae82a49d140febbbd0

+DEPENDS_openprotium = "mtd-utils"

   Think again - does u-boot-utils require mtd-utils headers or tools
during compile-time? Moreover, is it required for openprotium only?

+SRC_URI_append_openprotium = " \
+        file://fw_env.c.patch;patch=1 \
+        file://tools-Makefile.patch;patch=1 \
+        file://env-Makefile.patch;patch=1 \
+        file://fw_env.config"

   What so special of these patches that they apply only to
openprotium?

+EXTRA_OEMAKE_openprotium = "CROSS_COMPILE=${TARGET_PREFIX}"

   Overrides above are worth privilege of doubt, but this one doesn't
need it: doing things like this in the OE mainline is rather incorrect
behavior to all other projects/users.

 RDEPENDS_task-base-uboot = "\

+    u-boot-utils-native"

     More attention could have been spent here too - non-native
package *cannot* RDEPENDS on native, this is one of abort conditions
in insane.bbclass. Someone who added the original line thought that
uboot-utils is actually what its name suggests. When you'll be fixing
it, don't forget about this:

  I had a look at mkimage source, it appears to generate
target-independent format (does htonl() and friends), so it at least
can stay uboot-utils-native as the actual commit made it.

  More interestingly is that both u-boot and u-boot-utils-native stage
mkimage, and that's all what u-boot-utils-native does actually, so we
have redundancy here.

  Hm. Can't it be really built against just kernel headers? Pity, but
ok.

  Yes, I'd say the right way for mainline OE is to use machine/distro
overrides very sparingly, in selected places only. OE provides
flexible overrides mechanism to address special needs a vendor may have
to build its product per its requirements, but such overrides better live
in vendor trees/overlays. For mainline OE, I'd say it's better to err
on generality, than create complex and non-maintainable overrides maze
(an example is OPIE which risked removal from OE due to this, and by
now has been almost completely cleared off from any
machine-specific hacks).

  Let's hear Rod Whitby speak up, AFAIR, he added those features. But
as far as I understand, no, they should be there, and are the way to
add a particular bootloader support to *any* distro. Have a look at
apex and redboot support at the same place. So, if you say that your
machine has u-boot as bootloader, you'll get utils to manage it in the
image. Ditto for other bootloaders.

Sounds reasonable.  I'll adjust that.

Let me answer my own question here.  It appears that
MACHINE|DISTRO_FEATURES was serving two purposes - one -
to actually make a u-boot.bin file for the target, and two - to
generate mkimage on the build host.   Given the former, it
should definitely not go away!

A few kernels will need to add the u-boot-utils-native dependency,
notably the linkstation.  I'll make these adjustments in the commit.

Andy

Actually, I think NAiL added the uboot machine feature.  I only looked
at the uboot and redboot ones that were already there and added apex.

  Actually, that magic is pretty dumb ;-) :

# Not every device needs mkimage to generate a kernel image, but lets make OE a bit more
# friendly and increase the "Just Works(TM) factor. Building uboot takes only a minute. 
DEPENDS += " u-boot-mkimage-openmoko-native "

P.S. As of now, u-boot, u-boot-utils-native,
u-boot-mkimage-openmoko-native all stage mkimage. Waste. Need to
cleanup.

Please refresh your metadata ;)

Koen merged my code from Poky which adds mkimage dependency ONLY for 
uImage devices.
