cs89x0: Move the driver into the Cirrus dir
The cs89x0 driver was initial placed in the apple/ when it
should have been placed in the cirrus/. This resolves the
issue by moving the dirver and fixing up the respective
Kconfig(s) and Makefile(s).
Thanks to Sascha for reporting the issue.
-v2 Fix a config error that was introduced with v1 by removing
the dependency on MACE for NET_VENDOR_APPLE.

15 | Changelog: | ||
16 | |||
17 | Mike Cruse : mcruse@cti-ltd.com | ||
18 | : Changes for Linux 2.0 compatibility. | ||
19 | : Added dev_id parameter in net_interrupt(), | ||
20 | : request_irq() and free_irq(). Just NULL for now. | ||
21 | |||
22 | Mike Cruse : Added MOD_INC_USE_COUNT and MOD_DEC_USE_COUNT macros | ||
23 | : in net_open() and net_close() so kerneld would know | ||
24 | : that the module is in use and wouldn't eject the | ||
25 | : driver prematurely. | ||
26 | |||
27 | Mike Cruse : Rewrote init_module() and cleanup_module using 8390.c | ||
28 | : as an example. Disabled autoprobing in init_module(), | ||
29 | : not a good thing to do to other devices while Linux | ||
30 | : is running from all accounts. | ||
31 | |||
32 | Russ Nelson : Jul 13 1998. Added RxOnly DMA support. | ||
33 | |||
34 | Melody Lee : Aug 10 1999. Changes for Linux 2.2.5 compatibility. | ||
35 | : email: ethernet@crystal.cirrus.com | ||
36 | |||
37 | Alan Cox : Removed 1.2 support, added 2.1 extra counters. | ||
38 | |||
39 | Andrew Morton : Kernel 2.3.48 | ||
40 | : Handle kmalloc() failures | ||
41 | : Other resource allocation fixes | ||
42 | : Add SMP locks | ||
43 | : Integrate Russ Nelson's ALLOW_DMA functionality back in. | ||
44 | : If ALLOW_DMA is true, make DMA runtime selectable | ||
45 | : Folded in changes from Cirrus (Melody Lee | ||
46 | : <klee@crystal.cirrus.com>) | ||
47 | : Don't call netif_wake_queue() in net_send_packet() | ||
48 | : Fixed an out-of-mem bug in dma_rx() | ||
49 | : Updated Documentation/networking/cs89x0.txt | ||
50 | |||
51 | Andrew Morton : Kernel 2.3.99-pre1 | ||
52 | : Use skb_reserve to longword align IP header (two places) | ||
53 | : Remove a delay loop from dma_rx() | ||
54 | : Replace '100' with HZ | ||
55 | : Clean up a couple of skb API abuses | ||
56 | : Added 'cs89x0_dma=N' kernel boot option | ||
57 | : Correctly initialise lp->lock in non-module compile | ||
58 | |||
59 | Andrew Morton : Kernel 2.3.99-pre4-1 | ||
60 | : MOD_INC/DEC race fix (see | ||
61 | : http://www.uwsg.indiana.edu/hypermail/linux/kernel/0003.3/1532.html) | ||
62 | |||
63 | Andrew Morton : Kernel 2.4.0-test7-pre2 | ||
64 | : Enhanced EEPROM support to cover more devices, | ||
65 | : abstracted IRQ mapping to support CONFIG_ARCH_CLPS7500 arch | ||
66 | : (Jason Gunthorpe <jgg@ualberta.ca>) | ||
67 | |||
68 | Andrew Morton : Kernel 2.4.0-test11-pre4 | ||
69 | : Use dev->name in request_*() (Andrey Panin) | ||
70 | : Fix an error-path memleak in init_module() | ||
71 | : Preserve return value from request_irq() | ||
72 | : Fix type of `media' module parm (Keith Owens) | ||
73 | : Use SET_MODULE_OWNER() | ||
74 | : Tidied up strange request_irq() abuse in net_open(). | ||
75 | |||
76 | Andrew Morton : Kernel 2.4.3-pre1 | ||
77 | : Request correct number of pages for DMA (Hugh Dickens) | ||
78 | : Select PP_ChipID _after_ unregister_netdev in cleanup_module() | ||
79 | : because unregister_netdev() calls get_stats. | ||
80 | : Make `version[]' __initdata | ||
81 | : Uninlined the read/write reg/word functions. | ||
82 | |||
83 | Oskar Schirmer : oskar@scara.com | ||
84 | : HiCO.SH4 (superh) support added (irq#1, cs89x0_media=) | ||
