System: NetBSD katz.picovex.com 4.99.3 NetBSD 4.99.3 (BUCKY) #5: Fri Sep 29 17:38:54 PDT 2006 root@katz.picovex.com:/usr/obj/sys/arch/evbarm/compile/BUCKY evbarm
Architecture: evbarm
Machine: OSK5912
>Description:
NetBSD does not support the TI OMAP family of ARM processors
>How-To-Repeat:
Try to build NetBSD for OSK5912
>Fix:
Attached is a patch to add generic base support for systems based on the
OMAP 1 family. The devices supported in this patch are serial console
and MPU timers for OS timing purposes.
This patch depends upon patches previously sent by Scott Allan: "Three
small patches for ARM" on 07/26/2006 and "Patch to add support for
ARM9E" on 07/31/2006.
A staggering number of mobile phones, PDAs, and other portable devices
are based on these systems, and OMAP would make a great addition to
NetBSD. If there are any concerns we can address or other things we can
do to get this code accepted upstream please let me know, thanks,

+# connected to the second level interrupt controller should give the
+# second level interrupt controller's number plus 32 (the number of
+# interrupts that the first level controller has).
+# mult: Used to multiply the offsets given within a driver. For example, if
+# the driver expects byte registers at byte offsets, but they are mapped
+# in at word offsets, a mult of 4 would be specified. Note that the
+# size parameter is not multiplied by mult. If you specify a mult, in
+# general, you should probably be specifying a size to ensure that the
+# correct amount is mapped.

+# Extended Memory Interface Slow
+# Same parameters as for TIPB, but with the addition of parameters to
+# configure bus access. A parameter is provided to to force halfword access
+# instead of byte accesses:
+# nobyteacc: Allow 8-bit access for device with no lsb address line
+# If this is set to 1, if an attempt is made to write a single byte to the
+# bus, it will automatically get converted into reading a halfword, setting
+# the byte that is being written into the appropriate byte of the halfword,
+# and then writing the halfword to the bus.
+#
+# In addition to the nobyteacc parameter, a number of parameters are provided
+# to configure bus timing via the EMIFS_CCS and EMIFS_ACS registers. The cs
+# parameter specifies which chip-select should have its configuration
+# modified.
+#
+# NOTE: If the cs parameter is not specified, the EMIFS_CCS and EMIFS_ACS
+# registers will not be modified and all of the bus timing parameters will be
+# ignored.
+#
+# When cs is specified, EMIFS_CCS and EMIFS_ACS will be modified. In addition
+# to cs on your emifs device, you must specify the base parameter on the emifs
+# bus to tell it where its registers are. All fields of the EMIFS_CCS and
+# EMIFS_ACS registers will be set. The EMIFS will be set to be:
+#
+# asynchronous, non-page mode (RDMODE = 0)
+# non-multiplexed protocol
+# 16 bit wide
+# REF_CLK = TC_CK / 1
+#
+# The timing parameters are rdwst, oesetup, oehold, wrwst, welen, advhold,
+# btwst and btmode. All of them specify a number of nanoseconds, except
+# btmode which is a simple 0/1 flag.
+#
+# For a read cycle, CS will be held low for rdwst nanoseconds. The delay from
+# driving CS low to driving OE low is specified by oesetup. OE will go back
+# high oehold nanoseconds before CS goes back high.
+#
+# For a write cycle, CS will be held low for wrwst (time before WE goes low) +
+# welen (time WE is held low) + 1 REF_CLK cycle (time after WE goes high).
+#
+# For both read and write, advhold specifies how long ADV should be remain low
+# after it is driven low at the same time as CS.
+#
+# The bus turn around time (amount of time that CS needs to be high between
+# accesses) is specified by btwst and btmode. See the TRM for more
+# information.
+#
+# If btmode is not specified, it will be set to 0. All other timing
+# parameters will default to their minimum value.
