You are adding a new package: we need an entry in the DEVELOPERS file
for it.

Also, please add a hash file for this package.

The commit title should be:

	package/qcom-db410c-firmware: new package

it would perhaps be nice to have a bit of explanation in the commit log
about the oddities of this package. Or even better: a few comments
above the install target commands.

This should be in the patch adding the defconfig. In fact, your patch
1/3 adding the defconfig should be the last one in the series.

We like to have our traditional header here, like this:

yes, this is silly, but consistency wins over silliness :-)

Please set the version to just 1034.2.1, and encode the "r" in the
_SOURCE and _BASE variables.

Not needed, this is the default.

Not needed if you change a bit the next line.

Change to:

Doh, why are you using mcopy here? The files you need are burried
inside NON-HLOS.bin which is a FAT filesystem image ?

If you need mcopy, then you'll need a dependency on host-mtools, and
use $(HOST_DIR)/bin/mcopy instead, as you can't rely on mcopy being
available system-wide.

Thanks!

There should be one commit adding support for abootimg as a host
package, and then the commit adding the defconfig file together with
its post-image script.

This shouldn't be necessary: the linux package already installs the
kernel image and DTB in BINARIES_DIR. And this would avoid the need to
hardcode the KERNEL_BUILD directory.

Line commented, not needed.

This last line is not needed.

Instead, what we like is to have a board/qcom/db410c/readme.txt file
that explains how to use/build/flash this defconfig. See other
readme.txt files in board/ for a number of examples.

This looks good overall, but as explained in the review of the other
patches, this patch should come last in the series, once all the
preparation is done (adding a package for the firmware, host-abootimg
support). Also:

 - The commit title shoudld be just "configs/qcom_db410c: new defconfig"

 - An entry in the DEVELOPERS file should be added for the defconfig
   file and the board/qcom/db410c/ directory

 - A readme.txt should be added in board/qcom/db410c/readme.txt.
