[ts-7000] Opening /dev/mem more than once, is this bad?

["Blair" <>]

Is it a bad idea to open /dev/mem more than once in different sections of a 
program when you want to access different EP93xx registers?  Let's say you want 
to use the BGPIO lines, the HGPIO lines, and maybe the buffered input lines, 
and SPI lines which all have different base addresses.  Should you open 
/dev/mem and mmap for each of these areas or should you open /dev/mem once and 
pass that value to individual  mmap calls?
