README for Prisma kernel source diffs

The diffs were made against the uClinux/ColdFire source release
dated 6th July 2000. The main changes for the 68020 Prisma are:

+  New platform/board added: 68020/PRISMA.
+  Changes to the Makefiles and config files to add support for
   68020 and the Prisma.
+  Kernel re-compiled for 68020.
+  Userland re-compiled for 68000 ('elf2flt' does not correctly
   handle 68020 code).
+  New serial drivers for the TS68564 USART and TS68901 MFP based
   on the Linux-68k 'm68kserial.c'.
+  Modified A2065 network driver for the Prisma's on-board LANCE.
   (Note: the a2065 driver in the 2.0.38 sources is out of date,
   I have used the version from the Linux-68k 2.0.36 release as
   the base for my changes. Consequently the diff is much larger
   than it needs to be for the Prisma additions alone)
+  Configured for root on NFS with no ROMFS.

The changes / additions for the 68040 Prisma are:

+  New platform/board added: 68040/PRISMA40.
+  Changes to the Makefiles and config files to add support for
   68040 and the Prisma 40.
+  Kernel re-compiled for 68040.
+  Dummy serial driver for now, supports console ouput only
   (via ROM routines).
+  Modified Apricot network driver for the Prisma 40's on-board
   82596. This is based on the Linux-68k 82596 driver for the
   Motorola MVME cards. One change is to move the DMA buffers
   into non-cached SRAM in order to allow the data cache to be
   enabled for the kernel and userland in DRAM.
