-The MVME2100 is a Motorola VMEbus board which is similar to the other
-Motorola PowerPC boards supported by this BSP.  But it does not support
-the Motorola CPU Configuration Register.  This makes it impossible to
-dynamically probe and determine that you are executing on this board
-variant.  So this BSP variant must be explicitly built to only support
-the MVME2100.  The complete list of differences found so far is:
-
-  * No CPU Configuration Register
-  * one COM port
-  * COM port is on PCI IRQ not ISA IRQ
-  * limited on RAM (32 or 64 MB)
-  * uses the EPIC interrupt controller on the MPC8240
-  * does not have an ISA bus but has an ISA I/O address space
-  * cannot set DBAT2 in bspstart like other variants because
-    there are PCI/ISA Interrupt Acknowledge registers at this space
-    This BSP may have left some PCI memory uncovered
-  * PPCBug starts programs with vectors still in ROM
-
-Supported Features:
-  - Interrupt driven console using termios
-  - Network device driver
-  - Real-Time Clock driver
-  - Clock Tick Device Driver
-
-Things to address:
-  - Does not return to monitor
-  - Level 1 cache is disabled for now
-  - Check on trying to read CPU Configuration Register for CHRP/Prep for PCI
-    and report a failure if in the wrong mode.  May be able to set the model
-    but it may be hard to test if we break PPCBug.
-  - Use NVRAM for network configuration information
-
-BSP Features Not Implemented:
-  - VMEbus mapped in but untested
-  - OpenPIC features not required for BSP are not supported
-
