Variables are user-defined identifiers that symbolically represent a 
hardware register in terms of its offset, in either the CPU's I/O space or 
memory space.  Use of variables is required for system architectures in 
which dynamic configuration and multiple instances of the same hardware 
are possible.  A variable must be declared prior to being used.  See 
[Declarations] section in PMI Sections. 

<memory-mapped variable>  ::= <mmio variable>  =  'MMIO{'<number>'}'
<port-variable declaration>  ::= <pio variable>  = 'PIO{'<number>'}'
<mmio variable>  ::= <name>
<pio variable>  ::= <name>

For example: 

seq_address = PIO{0x3c4};
interrupt_en = MMIO{0x00000080}

Labels are user-defined identifiers that refer to code locations. The 
scope of a label is its containing function (or section). A label name 
within an adapter definition should be unique. The label must be declared 
prior to its reference. 

<label>  ::= <name>':'
