Why we need to consider u-boot size? (because it may cross the loader2 size?)
Here is the delta of u-boot elf

before:
text       data        bss        dec        hex    filename
 457378      20248     244160     721786      b037a    u-boot

after:
text       data        bss        dec        hex    filename
 461357      20848     244160     726365      b155d    u-boot
