MemTotal is the amount of free memory in the partition, which does not
include the memory that holds the kernel code, (bss, data, init).

There should be a few other pieces of data that will add up to the numbers
you are looking for.

in early boot messages, there is a line "SystemCfg->physicalMemorySize =
0x.......".   This value should be precisely what you are trying to

A bit later in the logs, you can also see a line
"Memory: XXXXk/YYYYk available (###k kernel code, ###k reserved, ###k data,
###k bss, ###k init).
the YYYYk should also match what you are looking for.
