For information, I merge the serie, except this patch 5/5 on master brach and I sent a pull request for u-boot-stm32-20200117.

For this patch, I propose a rebase and also many modification liked to my previous remark
(I remove ST only parts for stboard command, and also led and key management) .

This proposal is present in the branch https://gitlab.denx.de/u-boot/custodians/u-boot-stm/tree/next
	https://gitlab.denx.de/u-boot/custodians/u-boot-stm/commit/db48e11b1eccf23f3f9ba26e886a798e74df6a01

your initial patch is in applied https://gitlab.denx.de/u-boot/custodians/u-boot-stm/tree/dh
	

Can you test the "next" branch and check the difference with your initial patch ( applied in dh branch
https://gitlab.denx.de/u-boot/custodians/u-boot-stm/tree/dh 
=> https://gitlab.denx.de/u-boot/custodians/u-boot-stm/commit/0ab3ce72f82b946ac0924dfcdc082792f325eb68 )

I hope that I don't remove something really present on the SOM.

If you are OK, can you send a V2 version with the "next" branch content and I will integrate it in master branch for next pull request.

Thanks, 

Patrick
