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.

- Changelog:
-
- Mike Cruse : mcruse@cti-ltd.com
- : Changes for Linux 2.0 compatibility.
- : Added dev_id parameter in net_interrupt(),
- : request_irq() and free_irq(). Just NULL for now.
-
- Mike Cruse : Added MOD_INC_USE_COUNT and MOD_DEC_USE_COUNT macros
- : in net_open() and net_close() so kerneld would know
- : that the module is in use and wouldn't eject the
- : driver prematurely.
-
- Mike Cruse : Rewrote init_module() and cleanup_module using 8390.c
- : as an example. Disabled autoprobing in init_module(),
- : not a good thing to do to other devices while Linux
- : is running from all accounts.
-
- Russ Nelson : Jul 13 1998. Added RxOnly DMA support.
-
- Melody Lee : Aug 10 1999. Changes for Linux 2.2.5 compatibility.
- : email: ethernet@crystal.cirrus.com
-
- Alan Cox : Removed 1.2 support, added 2.1 extra counters.
-
- Andrew Morton : Kernel 2.3.48
- : Handle kmalloc() failures
- : Other resource allocation fixes
- : Add SMP locks
- : Integrate Russ Nelson's ALLOW_DMA functionality back in.
- : If ALLOW_DMA is true, make DMA runtime selectable
- : Folded in changes from Cirrus (Melody Lee
- : <klee@crystal.cirrus.com>)
- : Don't call netif_wake_queue() in net_send_packet()
- : Fixed an out-of-mem bug in dma_rx()
- : Updated Documentation/networking/cs89x0.txt
-
- Andrew Morton : Kernel 2.3.99-pre1
- : Use skb_reserve to longword align IP header (two places)
- : Remove a delay loop from dma_rx()
- : Replace '100' with HZ
- : Clean up a couple of skb API abuses
- : Added 'cs89x0_dma=N' kernel boot option
- : Correctly initialise lp->lock in non-module compile
-
- Andrew Morton : Kernel 2.3.99-pre4-1
- : MOD_INC/DEC race fix (see
- : http://www.uwsg.indiana.edu/hypermail/linux/kernel/0003.3/1532.html)
-
- Andrew Morton : Kernel 2.4.0-test7-pre2
- : Enhanced EEPROM support to cover more devices,
- : abstracted IRQ mapping to support CONFIG_ARCH_CLPS7500 arch
- : (Jason Gunthorpe <jgg@ualberta.ca>)
-
- Andrew Morton : Kernel 2.4.0-test11-pre4
- : Use dev->name in request_*() (Andrey Panin)
- : Fix an error-path memleak in init_module()
- : Preserve return value from request_irq()
- : Fix type of `media' module parm (Keith Owens)
- : Use SET_MODULE_OWNER()
- : Tidied up strange request_irq() abuse in net_open().
-
- Andrew Morton : Kernel 2.4.3-pre1
- : Request correct number of pages for DMA (Hugh Dickens)
- : Select PP_ChipID _after_ unregister_netdev in cleanup_module()
- : because unregister_netdev() calls get_stats.
- : Make `version[]' __initdata
- : Uninlined the read/write reg/word functions.
-
- Oskar Schirmer : oskar@scara.com
- : HiCO.SH4 (superh) support added (irq#1, cs89x0_media=)
-
- Deepak Saxena : dsaxena@plexity.net
- : Intel IXDP2x01 (XScale ixp2x00 NPU) platform support
-
- Dmitry Pervushin : dpervushin@ru.mvista.com
- : PNX010X platform support
-
- Deepak Saxena : dsaxena@plexity.net
- : Intel IXDP2351 platform support
-
- Dmitry Pervushin : dpervushin@ru.mvista.com
- : PNX010X platform support

-* media=t - specify media type

-* duplex=0 - specify forced half/full/autonegotiate duplex
-* debug=# - debug level
-
-
-* Default Chip Configuration:
- * DMA Burst = enabled
- * IOCHRDY Enabled = enabled
- * UseSA = enabled
- * CS8900 defaults to half-duplex if not specified on command-line
- * CS8920 defaults to autoneg if not specified on command-line
- * Use reset defaults for other config parameters
-
-* Assumptions:
- * media type specified is supported (circuitry is present)
- * if memory address is > 1MB, then required mem decode hw is present
- * if 10B-2, then agent other than driver will enable DC/DC converter
- (hw or software util)
