 Wow, this commit log is pretty dense... I rewrote it to the following:

configs/imx7dpico: Bump Linux and U-Boot

Bump Linux to 5.1 and U-Boot to version 2019.01.

U-Boot patch is no longer needed, applied upstream.

U-Boot defconfig name for this board has changed to pico-pi-imx7d.

U-Boot now supports distrobootcmd for this board, so add the appropriate
extlinux.conf and use SPL+u-boot.img instead of u-boot.imx. Note that
the common freescale post-image script handles things appropriately
based on the selected options in .config.


 However, I haven't applied yet because there's something I don't understand...

 So this will be placed in the rootfs, in the second partition. How does U-boot
know how to pick it up from there?

 I believe it doesn't, I don't think this file is used at all. It still works,
because the U-Boot config looks for zImage and imx7d-pico-pi.dtb on the first
partition by default.

 Please add a newline at the end of the file.

 How would uuid get expanded? How does U-Boot know the rootfs's UUID?

 However, I believe this file and the OVERLAY config option can just be removed.

[Buildroot] [PATCH 2/3] boards/freescale/common: Introduce template_no_boot_part

[Arnout Vandecappelle]

 Okay, this explains a lot... I should have read this patch before looking at
the previous one.

 So basically, patch 1 and 2 should be swapped.

 Note that I like this very much, I think it's silly that most of our defconfigs
still use a FAT partition.

 Is this one going to be used by anything in practice? I expect that anything
that uses this kind of layout is *not* going to use the .imx format, since
that's considered kind of deprecated...

 So my suggestion would be to remove it (also from the post-image script).

 Mention SPL here. And mention that SPL is at the offset expected by ROM, while
U-Boot is at the offset expected by SPL.

> +# * a single root filesystem partition is required (ext2, ext3 or ext4)

 Well, to be precise: the first partition is expected to be an ext2 and have a
/boot directory.

 I wasn't sure if this one depended on the kernel bump to 5.1, so I haven't
applied yet. Also, minor nits below.

It depends on the targets, imx7dpico has migrated to the SPL and so its 
u-boot has gone from .imx to .img,

Example of the warp7 on 2019.01 it's still .imx.

so I think that should not be removed.

 OK, let me rephrase it then: does U-Boot 2019.01 have any configuration without
boot FAT partition, but which uses the .imx format instead of SPL?

 In any case, I think this enimage.cfg.template_no_boot_part should only be
introduced when there is something that actually uses it. Now it is just dead code.

 Regards,
 Arnout

I see you are right if a target will need it it will introduce the 
variable I drop this file,

thanks for review
