Álvaro Fernández Rojas 76d5677c75 bmips: automatically detect RAM size
Introduce new patch for automatically detecting RAM size.
Some boards have a different amount of RAM depending on the HW revision.
Therefore, automatically detecting the RAM size instead of hard-coding it will
reduce the number of device definitions.
