When using a recent kernel with a bunch of compiled-in stuff the kernel image easily becomes bigger than 8 MB yielding this error:
Loading Kernel Image Image too large: increase CONFIG_SYS_BOOTM_LEN Must RESET board to recover
Fix this by bumping to SZ_16MB.

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.
