OpenBlockS600 (AMCC 405EX) again

[KIYOHARA Takashi <kiyohara%kk.iij4u.or.jp@localhost>]

Hi! ibm405 board maintainers and all,


Please see.

  http://mail-index.netbsd.org/current-users/2009/12/24/msg011832.html


I will commit these newer patchs at next week.

(will linked to newer patch ;-)
ftp://ftp.netbsd.org/pub/NetBSD/misc/kiyohara/openblocks600/powerpc-405ex.diff
ftp://ftp.netbsd.org/pub/NetBSD/misc/kiyohara/openblocks600/obs600.diff

I split older obs600.diff.
The former patch supports AMCC 405EX.  The latter patch supports
OpenBlockS600.


powerpc-405ex.diff:
  1. Add some new source and header files.
     (MAL(split) and RGMII(new) relations for EMAC)
  2. Create dcr4xx.h.  Its moved from dcr405gp.h.  Also remove dcr405xx.h.
  3. intr.c supports MULTIUIC with virtual-irq.  likes to oea.
     support 32-virq/128-hwirq.
  4. multiple emac support.
  5. WALNUT and VIRTEX_* includes arch/powerpc/conf/files.ibm4xx.
  6. WALNUT pci uses arch/powerpc/ibm4xx/pci/.

  7. Oops, ZMII not support.  I not have.


I test OpenBlockS600(405EX) and OpenBlockS266(405GPr).  OPENBLOCKS200,
EXPLORA451, WALNUT and VIRTEX_DSC compiles only.

However single-UIC supported by very old CPUs.  Should we always support
MULTIUIC?  (should remove #ifdef ?)

Thanks,
