11 If you have a network (Ethernet) card belonging to this class, say Y.
13 Note that the answer to this question doesn't directly affect the
14 kernel: saying N will just cause the configurator to skip all
15 the questions about WIZnet devices. If you say Y, you will be asked
16 for your specific card in the following questions.
21 tristate "WIZnet W5100 Ethernet support"
24 Support for WIZnet W5100 chips.
26 W5100 is a single chip with integrated 10/100 Ethernet MAC,
27 PHY and hardware TCP/IP stack, but this driver is limited to
28 the MAC and PHY functions only, onchip TCP/IP is unused.
30 To compile this driver as a module, choose M here: the module
34 tristate "WIZnet W5300 Ethernet support"
37 Support for WIZnet W5300 chips.
39 W5300 is a single chip with integrated 10/100 Ethernet MAC,
40 PHY and hardware TCP/IP stack, but this driver is limited to
41 the MAC and PHY functions only, onchip TCP/IP is unused.
43 To compile this driver as a module, choose M here: the module
47 prompt "WIZnet interface mode"
48 depends on WIZNET_W5100 || WIZNET_W5300
49 default WIZNET_BUS_ANY
51 config WIZNET_BUS_DIRECT
52 bool "Direct address bus mode"
54 In direct address mode host system can directly access all registers
55 after mapping to Memory-Mapped I/O space.
57 config WIZNET_BUS_INDIRECT
58 bool "Indirect address bus mode"
60 In indirect address mode host system indirectly accesses registers
61 using Indirect Mode Address Register and Indirect Mode Data Register,
62 which are directly mapped to Memory-Mapped I/O space.
65 bool "Select interface mode in runtime"
67 If interface mode is unknown in compile time, it can be selected
68 in runtime from board/platform resources configuration.
70 Performance may decrease compared to explicitly selected bus mode.
73 config WIZNET_W5100_SPI
74 tristate "WIZnet W5100/W5200/W5500 Ethernet support for SPI mode"
75 depends on WIZNET_BUS_ANY && WIZNET_W5100
78 In SPI mode host system accesses registers using SPI protocol
79 (mode 0) on the SPI bus.
81 Performance decreases compared to other bus interface mode.
82 In W5100 SPI mode, burst READ/WRITE processing are not provided.
84 To compile this driver as a module, choose M here: the module
85 will be called w5100-spi.
