Re: v2026.05.0

[Alexander Shiyan <eagle.alexander923@gmail.com>]

Hello Sascha.

The first launch of the new release has failed.
On the RK3568 platform, BL31 does not start. The size of the final
binary has decreased from 1.5 MB
to 930 KB - possibly due to the announced compression, but it seems to
me that this is too
large a reduction...
Are there any additional settings/calls required for custom boards in
the new release?

Thanks!
