Setting "Enable workarounds for booting old kernels" also changes a

rather then
looking at what the bootloader actually programmed. Other then that it
indeed
only changes "Boot in secure mode by default" which can be changed by
setting
the "bootm_boot_mode" env variable to either "sec" or "nonsec" before
calling
bootm.
Note that the latest sunxi-3.4/next kernels do not suffer from the PLL5
divider issue, and you can boot a new kernel just fine with the slightly
less optimal pll5 div chosen when building with "Enable workarounds
for booting
old kernels"
So yes you can boot both kernels with a single u-boot binary.

That's exactly the kind of information I was hoping to get. Thanks a lot.
