The @var{origin} is an expression for the start address of the memory
region. The expression must evaluate to a constant before memory
allocation is performed, which means that you may not use any section
relative symbols. The keyword @code{ORIGIN} may be abbreviated to
@code{org} or @code{o} (but not, for example, @code{ORG}).
The @var{origin} is an numerical expression for the start address of

The @var{len} is an expression for the size in bytes of the memory

In the following example, we specify that there are two memory regions
available for allocation: one starting at @samp{0} for 256 kilobytes,
