73a1170a8c sys/dev: use our nitems() macro when it is avaliable through param.h.
No functional change, only trivial cases are done in this sweep,
Drivers that can get further enhancements will be done independently.

cdd93ab812 Map the LAW for the RouterBoard's NAND LBC memory.
Without creating a LAW entry, any access to the NAND hangs the CPU.

The original intent was to add a quirk to map all of the RouterBoard's LBC
address space in one shot, which would fix it for both NAND and the CF, and
that's probably still in the cards.  However, for now, this makes NAND usable
without a separate hack.

Things left before the RouterBoard can run standalone:
* Add partitions to the NAND (not specified by the FDT, which we currently
  require).
* Create a YAFFS partition for the kernel.  The Mikrotik boot loader requires a
  4MB partition at the beginning of NAND, with a file called 'kernel' in the
  root.

fd90e2ed54 CALLOUT_MPSAFE has lost its meaning since r141428, i.e., for more than ten
years for head.  However, it is continuously misused as the mpsafe argument
for callout_init(9).  Deprecate the flag and clean up callout_init() calls
to make them more consistent.

98be38e7fb Implement a driver for the PowerPC-base RouterBoard (RB333/600/800/1100)
Summary:
This has been tested on the RB800, but should work on the RB333, RB600, and
RB1100 as well.

It's currently missing ECC support, but read and write are complete.

3da1cf1e88 Extend the meaning of the CTLFLAG_TUN flag to automatically check if
there is an environment variable which shall initialize the SYSCTL
during early boot. This works for all SYSCTL types both statically and
dynamically created ones, except for the SYSCTL NODE type and SYSCTLs
which belong to VNETs. A new flag, CTLFLAG_NOFETCH, has been added to
be used in the case a tunable sysctl has a custom initialisation
function allowing the sysctl to still be marked as a tunable. The
kernel SYSCTL API is mostly the same, with a few exceptions for some
special operations like iterating childrens of a static/extern SYSCTL
node. This operation should probably be made into a factored out
common macro, hence some device drivers use this. The reason for
changing the SYSCTL API was the need for a SYSCTL parent OID pointer
and not only the SYSCTL parent OID list pointer in order to quickly
generate the sysctl path. The motivation behind this patch is to avoid
parameter loading cludges inside the OFED driver subsystem. Instead of
adding special code to the OFED driver subsystem to post-load tunables
into dynamically created sysctls, we generalize this in the kernel.

Other changes:
- Corrected a possibly incorrect sysctl name from "hw.cbb.intr_mask"
to "hw.pcic.intr_mask".
- Removed redundant TUNABLE statements throughout the kernel.
- Some minor code rewrites in connection to removing not needed
TUNABLE statements.
- Added a missing SYSCTL_DECL().
- Wrapped two very long lines.
- Avoid malloc()/free() inside sysctl string handling, in case it is
called to initialize a sysctl from a tunable, hence malloc()/free() is
not ready when sysctls from the sysctl dataset are registered.
- Bumped FreeBSD version to indicate SYSCTL API change.

97eb0c3c6a Add fdt binding for nand for Atmel parts. This does little more than
match the device. Pinctrl will need to be added before this will work,
in addition to migrating the current board_foo.c method of configuring
these pins to something else. Non-FDT systems won't be affected, yet.

380ff59ab1 Add support for Samsung K9F2G08U0A (256MiB SLC) NAND found on some old
Atmel boards I have.

# All Samsung, Toshiba and SanDisk parts will need to be in this table
# since they don't conform to the ONFI specification (they are all Toggle
# parts). There's some standards for the additional bytes so there's some hope
# to decode them automatically on a per-vendor basis, but even that has
# problems (and is what motivated the ONFI parameter page).

774b082ca9 Rework the routine that returns a pointer to the table of software ECC
byte positions within the OOB area to support chips with unusual OOB
sizes such as 218 or 224 bytes.

The table for 128 byte OOB works for these but it assumes 3 bytes of ECC
per 256 byte block, and in the case of an ONFI chip the params page may
ask for something different.  In other words, this is better but not
yet perfect.

c3c04faa3a ONFI parameters are little-endian, hence we must take care to convert them
to native endianness.  We must also pay attention to unaligned accesses.

Copy the interesting parameters to a new struct so the rest of the code can
forget about these problems.

1b45c6cd53 Search for and validate the ONFI params as specified in the standard.
The ONFI spec states that at least two bytes of the signature ("ONFI")
must be present, and the CRC must be correct to have a valid parameter
page.  If the page is not valid there are at least two backup pages where
the data can also be found.

ce4bc82d19 Use direct custom implementations instead of g_handleattr() for CFI and NAND
d_getattr().  Since these drivers use disk(9) KPI and not directly GEOM, use
of that function means KPI layering violation, causing extra g_io_deliver()

filesystem module, remove the VFS_LOCK_GIANT() and related
macros. Stop handling buffers belonging to non-mpsafe filesystems.

The VFS_VERSION is bumped to indicate the interface change which does
