[Buildroot] [PATCH 0/3] imx: update Boundary Devices boards support

[Gary Bisson]

Hi,

I'm back at Boundary Devices and decided to revive its i.MX support in
Buildroot. So here is a first series to update BD support:
- Updating U-Boot / bootscript
- Adding 8MMini device support

Let me know if you have any questions.

Regards,
Gary

Hello Gary,

I was about to apply, but there are a few things that could be
improved. See below.

Could you update board/boundary/common/readme.txt to also list this
platform as being supported, and any other note that might be relevant ?

Could you drop this script and use support/scripts/genimage.sh ?
Indeed, it does the same thing, and in fact support/scripts/genimage.sh
got fixed to use an empty rootpath and avoid a useless extra copy
(commit 31d1fb27b0e62a6542112a7476ff188f2f7b8d38).

It would be good to do that in a preparation commit for all existing
Boundary Devices boards.

Thanks!

Thomas

Yes good catch I'll make sure to update it.

Sure will do, didn't know about that script ;)

Yep I'll align all boards to use that script.
