[2.6 patch] ppc: remove APUS support (fwd)

Subject: [2.6 patch] ppc: remove APUS support

Current status of APUS:
- arch/powerpc/: removed in 2.6.23
- arch/ppc/: marked BROKEN since 2 years

This patch therefore removes the remaining parts of APUS support.

- * Amiga Linux interrupt handling code
- *
- * This file is subject to the terms and conditions of the GNU General Public
- * License.  See the file COPYING in the main directory of this archive
- * for more details.
- *
- * 11/07/96: rewritten interrupt handling, irq lists are exists now only for
- *           this sources where it makes sense (VERTB/PORTS/EXTER) and you must
- *           be careful that dev_id for this sources is unique since this the
- *           only possibility to distinguish between different handlers for
- *           free_irq. irq lists also have different irq flags:
- *           - IRQ_FLG_FAST: handler is inserted at top of list (after other
- *                           fast handlers)
- *           - IRQ_FLG_SLOW: handler is inserted at bottom of list and before
- *                           they're executed irq level is set to the previous
- *                           one, but handlers don't need to be reentrant, if
- *                           reentrance occurred, slow handlers will be just
- *                           called again.
- *           The whole interrupt handling for CIAs is moved to cia.c
- *           /Roman Zippel
- *
- * 07/08/99: rewamp of the interrupt handling - we now have two types of
- *           interrupts, normal and fast handlers, fast handlers being
- *           marked with SA_INTERRUPT and runs with all other interrupts
- *           disabled. Normal interrupts disable their own source but
- *           run with all other interrupt sources enabled.
- *           PORTS and EXTER interrupts are always shared even if the
- *           drivers do not explicitly mark this when calling
- *           request_irq which they really should do.
- *           This is similar to the way interrupts are handled on all
- *           other architectures and makes a ton of sense besides
- *           having the advantage of making it easier to share
- *           drivers.
- *           /Jes

    [POWERPC] Remove the dregs of APUS support from arch/powerpc
    
    APUS (the Amiga Power-Up System) is not supported under arch/powerpc
    and it's unlikely it ever will be.  Therefore, this patch removes the
    fragments of APUS support code from arch/powerpc which have been
    copied from arch/ppc.
    
    A few APUS references are left in asm-powerpc in .h files which are
    still used from arch/ppc.

okay - so surely moving the APUS out of powerpc is a *bad* idea? 
(ie that patch would need to be reverse to get the bits back in....)

whats broken with APUS in the powerpc as it stands?

arch/ppc (32 bit only) is planned to go away.
arch/powerpc (32 and 64 bit support in one tree) is where all new
development is done and where all arch/ppc platforms should be migrated to.

so it is only supported under arch/ppc ?  what are the losses of not being
under powerpc ?

Subject: [PATCH 4/7] Remove the dregs of APUS support from arch/powerpc

APUS (the Amiga Power-Up System) is not supported under arch/powerpc
and it's unlikely it ever will be.  Therefore, this patch removes the
fragments of APUS support code from arch/powerpc which have been
copied from arch/ppc.

A few APUS references are left in asm-powerpc in .h files which are
still used from arch/ppc.

I'm good with removing GEMINI since no one seems to have raised any  
fuss about this and I brought the issue up over a year ago now.   
However, I leave the final decision up to Paul.

Also, where do we stand with APUS?

I just saw the commit message below.

There seems to have been some although unmerged work on APUS support by 
Roman, but I didn't find any recent work on bringing the GEMINI support 
back into life.

Is this a wrong impression, or would a patch to remove it be OK?

    [PATCH] ppc32: Mark boards that don't build as BROKEN
    
    Marked APUS and GEMINI as BROKEN since they do not build at the platform
    level.  We have requested that the maintainers of these boards/platforms
    fix them by the time 2.6.15 is released or we plan on concerning them
    unmaintained and thus removing them.

That stuff is quite old and I only fixed it as needed, so I'm not 100% 
sure how it's used completely.
Anyway, AFAICT they mainly used by non-APUS specific drivers, mainly that 
would be the permedia fb driver. To make things worse I think this 
hardware is connected with some simple PCI adapter working in big endian 
mode.
Everything else should use the zorro specific functions, where I added an 
eieio(). I agree that it's a mess and I haven't worked on it for a long 
time, everytime I attempted to clean this stuff up, patches have been 
welcomed with such enthusiasm, that I'd rather continued hacking on 
something else...

Somebody who understands APUS around ?

In include/asm-ppc/io.h, we have a special definition of the PCI IO
accessors readw,writew,readl and writel for APUS that don't do byteswap
and also don't do barriers.

This seems very bogus to me. Can somebody explain me why it's done that
way so I can then explain why it's broken ? :-)

I will remove those definitions soon, so unless I get a very convincing
argument of why it has to be done that way on APUS, things might break
(APUS-specific drivers relying on those not swapping will have to be
fixed).

Ben.
