2 # Blackfin device configuration
6 bool "Blackfin devices"
7 depends on BF516 || BF518 || BF526 || BF527 || BF536 || BF537
9 If you have a network (Ethernet) card belonging to this class, say Y.
10 Make sure you know the name of your card. Read the Ethernet-HOWTO,
11 available from <http://www.tldp.org/docs.html#howto>.
15 Note that the answer to this question doesn't directly affect the
16 kernel: saying N will just cause the configurator to skip all
17 the remaining Blackfin card questions. If you say Y, you will be
18 asked for your specific card in the following questions.
23 tristate "Blackfin on-chip MAC support"
24 depends on (BF516 || BF518 || BF526 || BF527 || BF536 || BF537)
29 select BFIN_MAC_USE_L1 if DMA_UNCACHED_NONE
31 This is the driver for Blackfin on-chip mac device. Say Y if you want
32 it compiled into the kernel. This driver is also available as a
33 module ( = code which can be inserted in and removed from the running
34 kernel whenever you want). The module will be called bfin_mac.
36 config BFIN_MAC_USE_L1
37 bool "Use L1 memory for rx/tx packets"
38 depends on BFIN_MAC && (BF527 || BF537)
41 To get maximum network performance, you should use L1 memory as rx/tx
42 buffers. Say N here if you want to reserve L1 memory for other uses.
44 config BFIN_TX_DESC_NUM
45 int "Number of transmit buffer packets"
47 range 6 10 if BFIN_MAC_USE_L1
51 Set the number of buffer packets used in driver.
53 config BFIN_RX_DESC_NUM
54 int "Number of receive buffer packets"
56 range 20 100 if BFIN_MAC_USE_L1
60 Set the number of buffer packets used in driver.
62 config BFIN_MAC_USE_HWSTAMP
63 bool "Use IEEE 1588 hwstamp"
64 depends on BFIN_MAC && BF518
67 To support the IEEE 1588 Precision Time Protocol (PTP), select y here
