IXP425 - 266mhz
32mb SDRAM
8mb Flash
miniPCI slot 0 does not have a card connector soldered to the board
miniPCI slot 1 has an ISL3880 802.11g card (Prism54)
npe0 is connected to a Kendin KS8995M Switch (4 ports)
npe1 is the "wan" port
"Console" UART is available on J11 as console
"High Speed" UART is n/c (as far as I can tell)
20 Pin ARM/Xscale JTAG interface on J2
comment "IXP4xx Options"
config IXP4XX_INDIRECT_PCI
bool "Use indirect PCI memory access"
help
IXP4xx provides two methods of accessing PCI memory space:
1) A direct mapped window from 0x48000000 to 0x4bffffff (64MB).
To access PCI via this space, we simply ioremap() the BAR
into the kernel and we can use the standard read[bwl]/write[bwl]
macros. This is the preferred method due to speed but it
limits the system to just 64MB of PCI memory. This can be
problamatic if using video cards and other memory-heavy devices.
2) If > 64MB of memory space is required, the IXP4xx can be
configured to use indirect registers to access PCI This allows
for up to 128MB (0x48000000 to 0x4fffffff) of memory on the bus.
The disadvantadge of this is that every PCI access requires
three local register accesses plus a spinlock, but in some
cases the performance hit is acceptable. In addition, you cannot
mmap() PCI devices in this case due to the indirect nature
of the PCI window.
By default, the direct method is used. Choose this option if you
need to use the indirect method instead. If you don't know
what you need, leave this option unselected.
