In a school project we were originally going to use a 2106, but have
decided to move to a 2138 due to extra GPIO pins and External
Interrupts that are edge sensitve.  We have been sucessfully
developing for the 2106 with no problems using GCC and .ld and crt.s
files from an example project.  What will need to be changed when
going to the 2138.  I know the following will need to be corrected in
the .ld file:

/* Memory Definitions */
MEMORY
{
  ROM (rx) : ORIGIN = 0x00000000, LENGTH = 0x00020000
  RAM (rw) : ORIGIN = 0x40000000, LENGTH = 0x00010000
}

Is this all that will need to be changed?

Thanks,
