[PATCH v4 2/3] ipq40xx: dts: allow writing to U-Boot environment

Tomasz Maciej Nowak tmn505 at terefe.re
Thu Jul 27 09:45:15 PDT 2023 

From: Tomasz Maciej Nowak <tmn505 at gmail.com>

Devices allowing to boot LZMA or GZIP compressed kernel didn't hit yet
the 4MiB boundary for kernel size, thus allowing to prepare workaround
for the issue, without need for serial console attachment.
The workaround is modifying 'bootcmd' variable in U-Boot environment
which will replace 'bootipq' command with equivalent not limited by
imposed partition table.
This commit also touches devices which boot uncompressed kernel, so
even if those are already soft-bricked, it will still allow to alter
U-Boot environment from initramfs booted device.
