The CONFIG_SYS_BOOTMAPSZ thing is as old as U-Boot and PPCBoot exists, i. e. well over a decade. IIRC there was such a limitation on the then current 2.2.13 Linux kernels, at least on MPC8xx and PPC40x systems, which is where all started from. I am pretty sure that as long as nobody ran into any problems, nobody looked into that code, so it was copied from architecture to architecture without much thinking, if any.
