The DragonBoard 410c has proprietary firmware from Qualcomm that
reserves 8 MiB of memory for tz/smem/hyp/rmtfs/rfsa from 0x86000000
to 0x86800000. I'm not aware of any ATF (ARM Trusted Firmware) port
for DB410c that would reserve 30 MiB of memory at the end of RAM.
I suspect the comment might have been copied from hikey.h which has
a very similar comment (and which actually does have an ATF port).
Reducing the memory size just prevents U-Boot from using the end of
the RAM, not the reserved region inbetween. Therefore we might as well
display the correct DRAM size (1 GiB) instead of strange 986 MiB.
