58 # IXCDP1100 is the exact same HW as IXDP425, but with a different machine
59 # number from the bootloader due to marketing monkeys, so we just enable it
60 # by default if IXDP425 is enabled.

91 bool "Gemtek WX5715 (Linksys WRV54G)"
92 depends on ARCH_IXP4XX
94 This board is currently inside the Linksys WRV54G Gateways.
99 miniPCI slot 0 does not have a card connector soldered to the board
100 miniPCI slot 1 has an ISL3880 802.11g card (Prism54)
101 npe0 is connected to a Kendin KS8995M Switch (4 ports)
102 npe1 is the "wan" port
103 "Console" UART is available on J11 as console
104 "High Speed" UART is n/c (as far as I can tell)
105 20 Pin ARM/Xscale JTAG interface on J2

110 config IXP4XX_INDIRECT_PCI
111 bool "Use indirect PCI memory access"
113 IXP4xx provides two methods of accessing PCI memory space:
115 1) A direct mapped window from 0x48000000 to 0x4bffffff (64MB).
116 To access PCI via this space, we simply ioremap() the BAR
117 into the kernel and we can use the standard read[bwl]/write[bwl]
118 macros. This is the preferred method due to speed but it
119 limits the system to just 64MB of PCI memory. This can be
120 problamatic if using video cards and other memory-heavy devices.
122 2) If > 64MB of memory space is required, the IXP4xx can be
123 configured to use indirect registers to access PCI This allows
124 for up to 128MB (0x48000000 to 0x4fffffff) of memory on the bus.
125 The disadvantadge of this is that every PCI access requires
126 three local register accesses plus a spinlock, but in some
127 cases the performance hit is acceptable. In addition, you cannot
128 mmap() PCI devices in this case due to the indirect nature
131 By default, the direct method is used. Choose this option if you
132 need to use the indirect method instead. If you don't know
133 what you need, leave this option unselected.
