[POWERPC] Remove APUS support from arch/ppc
Current status of APUS: - arch/powerpc/: removed in 2.6.23 - arch/ppc/: marked BROKEN since 2 years This therefore removes the remaining parts of APUS support from arch/ppc, include/asm-ppc, arch/powerpc and include/asm-powerpc.

1111 a max of 19,200 bps, the ports are served by a 6551 ACIA UART chip
1112 each, plus a 8520 CIA, and a master 6502 CPU and buffer as well. The
1113 ports were connected with 8 pin DIN connectors on the card bracket,
1114 for which 8 pin to DB25 adapters were supplied. The card also had
1115 jumpers internally to toggle various pinning configurations.

5 * License. See the file COPYING in the main directory of this archive
6 * for more details.
7 *
8 * 11/07/96: rewritten interrupt handling, irq lists are exists now only for
9 * this sources where it makes sense (VERTB/PORTS/EXTER) and you must
10 * be careful that dev_id for this sources is unique since this the
11 * only possibility to distinguish between different handlers for
12 * free_irq. irq lists also have different irq flags:
13 * - IRQ_FLG_FAST: handler is inserted at top of list (after other
14 * fast handlers)
15 * - IRQ_FLG_SLOW: handler is inserted at bottom of list and before
16 * they're executed irq level is set to the previous
17 * one, but handlers don't need to be reentrant, if
18 * reentrance occurred, slow handlers will be just
19 * called again.
20 * The whole interrupt handling for CIAs is moved to cia.c
21 * /Roman Zippel
22 *
23 * 07/08/99: rewamp of the interrupt handling - we now have two types of
24 * interrupts, normal and fast handlers, fast handlers being
25 * marked with SA_INTERRUPT and runs with all other interrupts
26 * disabled. Normal interrupts disable their own source but
27 * run with all other interrupt sources enabled.
28 * PORTS and EXTER interrupts are always shared even if the
29 * drivers do not explicitly mark this when calling
30 * request_irq which they really should do.
31 * This is similar to the way interrupts are handled on all
32 * other architectures and makes a ton of sense besides
33 * having the advantage of making it easier to share
34 * drivers.
