With some kernels, not all memory is allocated to the kernel unless you pass

Since special Octeon code consumes the "mem=..." parameter, it isn't
available in userspace after the kernel is booted, so you must look at what
is done in u-boot.
Well, that didn't work out too well (see below).
Do I need to tweak the device tree or
'arch/mips/cavium-octeon/setup.c' for my specific board?
What board it it?
Allocated memory for ELF segment: addr: 0x1100000, size 0x2628a48
Why not show the entire logs we could know what you are doing in u-boot?
