All the maintained platforms are now in arch/powerpc, so the old
arch/ppc stuff can now go away.

- * Copyright (c) 1997 Dan Malek (dmalek@jlc.net)
- *
- * In addition to the individual control of the communication
- * channels, there are a few functions that globally affect the
- * communication processor.
- *
- * Buffer descriptors must be allocated from the dual ported memory
- * space.  The allocator for that is here.  When the communication
- * process is reset, we reclaim the memory available.  There is
- * currently no deallocator for this memory.
- * The amount of space available is platform dependent.  On the
- * MBX, the EPPC software loads additional microcode into the
- * communication processor, and uses some of the DP ram for this
- * purpose.  Current, the first 512 bytes and the last 256 bytes of
- * memory are used.  Right now I am conservative and only use the
- * memory that can never be used for microcode.  If there are
- * applications that require more DP ram, we can expand the boundaries
- * but then we have to be careful of any downloaded microcode.
