+
+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
