Initial import of Linux/Vendor DTS files for various embedded boards.
Initial import of DTS files from Linux
Correct initial import script
New AT91 devices or fdt probe added to existing devices. Some of these
are just stubs for testing the new dts.
- nand
- SDRAMC
- shdwc
- tcb
- usb host and gadget
Provide a simplified way to specify GPIO pins for the Atmel port.
Add at91 data so we can convert a PIO unit number into a base address.
Add at91 standard memory controller helper functions.
Generalize AT91 NAND support a bit.
Connect NAND for the SAM9260EK eval board, as well as the HotE HL-201.
Add nand device and NANDFS into the mix for those at91 boards that have
support for it at the moment.
Allow AT91_MCI_ALLOW_OVERCLOCK to be an option in kernel config files.
Set the SoC name for the atmelbus name.
Add support for Samsung K9F2G08U0A (256MiB SLC) NAND
Comment updates.
Look up a nand chip by id in the static table before trying to obtain
ONFI parameters. This allows a static table entry to provide valid data
for chips known to provide invalid ONFI data.
Add ONFI signature check.
Add Micron chip found in Freescale Vybrid Family Phytec COSMIC board.
The vendor specified field is 88 bytes, not 8 bytes.
Update the onfi_params struct to ONFI revision 3.2 (06 12 2013).
Search for and validate the ONFI params as specified in the standard.
ONFI parameters are little-endian, hence we must take care to convert them
to native endianness. We must also pay attention to unaligned accesses.
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.
Split raw reading/programming into smaller chunks to avoid allocating too
big chunk of kernel memory. Validate size of data. Add error handling to
avoid calling copyout() when data has not been read correctly. Also MFC of
change r258425 which fixes problem introduced by r258387.

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()
call for the request.
In particular, do not lock Giant conditionally when calling into the
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
not result in the interface signatures changes.

This driver does not yet handle multiple chip selects properly.
Note that the NAND infrastructure does not perform full page
reads or writes, which means that this driver cannot make use
of the hardware ECC that is otherwise present.
The NAND Flash environment consists of several distinct components:
- NAND framework (drivers harness for NAND controllers and NAND chips)
- NAND simulator (NANDsim)
- NAND file system (NAND FS)
- Companion tools and utilities
- Documentation (manual pages)
This work is still experimental. Please use with caution.
