So, the default for CONFIG_SYS_BOOTM_LEN is clearly too small and should
be addressed broadly.  And, ugh, I don't see a maximum size for the
kernel itself in
https://www.kernel.org/doc/Documentation/arm64/booting.rst but SZ_64M is
the common "we hope this is always large enough" value used, so can we
push stemmy there as well?  Thanks.
