[ptxdist] [PATCH v2 1/2] dtc: Seperate path and filename of dts

[ptxdist] [PATCH v2 1/2] dtc: Seperate path and filename of dts

[Teresa Gámez]

Creating multiple device trees result in a quite
long DTC_OFTREE_DTS variable. Splitting it into a
path variable and file variable makes it more handy.

[ptxdist] [PATCH v2 2/2] barebox_mlo: use images/barebox-*-mlo.img as images

[Teresa Gámez]

New barebox versions may create multiple MLO images.
Adapted barebox_mlo rule to handle this.

little nitpick here. This produce an output of "/foo/bar/boot/dts//bar.foo".
								 ^^
					this will not generate a nice output

Sorry, I said in my previous mail
"${KERNEL_DIR}/arch/${PTXCONF_KERNEL_ARCH_STRING}/boot/dts/"... but I
was a little bit too fast and did not remove the '/'. :-(

Re: [ptxdist] [PATCH v2 1/2] dtc: Seperate path and filename of dts

[Alexander Aring]

I detected a new issue with this patch.


First:

Before it was possible to have something like:

PTXCONF_DTC_OFTREE_DTS="/bar/foo/foobar.dts /foo/bar/barfoo.dts"

These files have a different basename. With your patch the basename must
be one unique basename. I mean okay, we could drop this and force the
ptxdist users that all dts files need to be under one location.

or

we make a for-each to search all directories of DTS_PATH, then we could
configure something like that:

DTC_OFTREE_DTS_PATHS="/bar/foo /foo/bar"
DTC_OFTREE_DTS="foobar.dts barfoo.dts"



Second:

We should write some migrate sed pattern for
"scripts/migrate/migrate_ptx". I think this becomes a little bit
complicated, if you like I can try to help you there. ;)

Hi,

I've rewritten the patch taking these issues into account.
I'll merge it after the release.

I've used ':' as a separater for the path.

Doing this correctly in sed seems rather complex:
- don't do anything if DTC_OFTREE_DTS_PATHS is already set
- move all directories to DTC_OFTREE_DTS_PATHS
- make them unique

Instead I've done this backwards compatible: Don't add DTC_OFTREE_DTS_PATHS
if the filename starts with '/'.

just to clarify, what's the priority in this list?

Should we do that like PATH? Then I would prefer

${KERNEL_DIR}/arch/${PTXCONF_KERNEL_ARCH_STRING}/boot/dts:${PTXDIST_PLATFORMCONFIGDIR}/dts

instead

${PTXDIST_PLATFORMCONFIGDIR}/dts:${KERNEL_DIR}/arch/${PTXCONF_KERNEL_ARCH_STRING}/boot/dts

as default value. Then I can just copy the mainline dts file to ${PTXDIST_PLATFORMCONFIGDIR}/dts
without renaming and make some platform changes.
