[Buildroot] [PATCH] configs/nanopi_neo: update kernel to 5.3

[Thomas Petazzoni <thomas.petazzoni@bootlin.com>]

Hello Viktar,

Thanks for your contribution! However, I have a number of comments, see
below.

The first comment is that this commit makes a number of changes that
are not directly related to each other. Another comment is that the
commit title doesn't reflect what the patch is doing (the commit title
only mentions the Linux update to 5.3, but none of the other changes).

This size field should be completely dropped, genimage can figure out
the partition size from the filesystem image size.

This should be one separate patch.

Dropping the post-image/post-build scripts is a good idea, but it
should be another separate patch from bumping the versions of
Linux/U-Boot.

Good that you drop this, can be part of the patch dropping the size in
the genimage.cfg file as well.

Should be in the patch removing the post-build and post-image scripts.

Same.

Could you rework your patch according to the comments above?
Ultimately, we want 3 patches:

 - One fixing the filesystem size usage
 - One removing post-build/post-image script
 - One doing the update of Linux/U-Boot versions

Thanks!
