Subject: [PATCH] imx6: apalis: Make the boot process more generic
|
||||
MIME-Version: 1.0
|
||||
Content-Type: text/plain; charset=UTF-8
|
||||
Content-Transfer-Encoding: 8bit
|
||||
|
||||
I'm preparing support for Apalis imx6 boards in OpenWrt and I've ended
|
||||
up with quite huge patchset against upstream U-Boot 2018.03, so I'm
|
||||
trying to propose more generic way of boot process handling.
|
||||
|
||||
In OpenWrt we usually have kernel, dtbs and U-Boot boot script in boot
|
||||
partition with ext4fs, so for some use cases it would be handy to be
|
||||
able to replace some of the files in the boot partion, that's why I've
|
||||
added write support to the ext4.
|
||||
|
||||
I've added `set_blkcnt` environment variable which is needed for every
|
||||
`mmc write` command as we need to always specify size in block count.
|
||||
This is copy&pasted from official Toradex's flashing scripts, so all the
|
||||
credits for this work belongs to them.
|
||||
|
||||
Currently the rootfs location is passed via mmcblk number and the
|
||||
problem with this approach is that the mmcblk number for the boot device
|
||||
changes depending on the kernel version and imx6 SoC type. In order to
|
||||
avoid such issues, use the UUID method to specify the rootfs location.
|
||||
|
||||
I've added new boot sequence, where we first try to load and run boot
|
||||
script defined in the new `script` variable, so the boot process could
|
||||
be more generic and overridden by the distro. When the boot script isn't
|
||||
loaded, it will use the previous boot sequence so it should be backward
|
||||
compatible.
|
||||
|
||||
For the recovery purposes and better end user experience I've added boot
|
||||
from SDP as the last boot command if every other boot option fails. I
|
||||
plan to use SDP as official flashing/recovery procedure in OpenWrt for
|
||||
Apalis imx6 boards.
|
||||
|
||||
I've copy&pasted almost everything from the `f086812a mx6sxsabresd: Use
|
||||
PARTUUID to specify the rootfs location` commit, so credits for the rest
|
||||
of this patch belongs to Fabio.
