Hey,
Can you please test and then enable support for LTO on these platforms?
They're very close to their binary size limit and while I have been
pushing for people to look to reduce the size of new features when
added, and tripping the limit here, I'm now looking at
https://lore.kernel.org/r/20261027-spi-probe-speed-v3-1-33e056720925@iav.lv
being a fix that pushes them over-limit. Thanks!

I will look on that in the following days.
And indeed - for imx28 the binary (especially SPL) size is critical.
When exceeded, due to ROM code design, the boot is broken and board
gets bricked.
