- Copy stable/10 (r259064) to releng/10.0 as part of the 10.0-RELEASE cycle. - Update __FreeBSD_version [1] - Set branch name to -RC1
[1] 10.0-CURRENT __FreeBSD_version value ended at '55', so start releng/10.0 at '100' so the branch is started with a value ending in zero.

MFC r256753
MFP4: 1136252
Add an option ATSE_CFI_HACK to allow memory mapped CFI devices to have their address range allocated sharable so that atse(4) can find it's Ethernet address in the expected location.
We intend to remove this hack once the BERI platform has a loader.

Rework the timeout code to use actual time rather than a DELAY() loop and to use both typical and maximum to allow logging of timeout failures. Also correct the erase timeout, it is specified in milliseconds not microseconds like the other timeouts. Do not invoke DELAY() between status queries as this adds significant latency which in turn reduced write performance substantially.
Sanity check timeout values from the hardware.
Implement support for buffered writes (only enabled on Intel/Sharp parts for now). This yields an order of magnitude speedup on the 64MB Intel StrataFlash parts we use.
When making a copy of the block to modify, also keep a clean copy around until we are ready to commit the block and use it to avoid unnecessary erases. In the non-buffer write case, also use it to avoid unnecessary writes when the block has not been erased. This yields a significant speedup when doing things like zeroing a block.

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() call for the request.

CFI fixes for big endian archs.
The flash commands and responses are little-endian and have to be byte swapped on big-endian systems. However the raw read of data need not be swapped.
Make the cfi_read and cfi_write do the swapping, and provide a cfi_read_raw which does not byte swap for reading data from flash.

Merge r221614,221696,221737,221840 from largeSMP project branch: Rewrite atomic operations for powerpc in order to achieve the following: - Produce a type-clean implementation (in terms of functions arguments and returned values) for the primitives. - Fix errors with _long() atomics where they ended up with the wrong arguments to be accepted. - Follow the sys/type.h specifics that define the numbered types starting from standard C types. - Let _ptr() version to not auto-magically cast arguments, but leave the burden on callers, as _ptr() atomic is intended to be used relatively rarely.
Fix cfi in order to support the latest point.

Convert Freescale PowerPC platforms to FDT convention.
The following systems are affected:
- MPC8555CDS - MPC8572DS
This overhaul covers the following major changes:
- All integrated peripherals drivers for Freescale MPC85XX SoC, which are currently in the FreeBSD source tree are reworked and adjusted so they derive config data out of the device tree blob (instead of hard coded / tabelarized values).
- This includes: LBC, PCI / PCI-Express, I2C, DS1553, OpenPIC, TSEC, SEC, QUICC, UART, CFI.
- Thanks to the common FDT infrastrucutre (fdtbus, simplebus) we retire ocpbus(4) driver, which was based on hard-coded config data.
Note that world for these platforms has to be built WITH_FDT.

Note: writing the user segment isn't correct; committing now to get review.

Add a driver for flash memory that implements to the Common Flash Memory Interface (CFI). The flash memory can be read and written to through /dev/cfi# and an ioctl() exists so processes can read the query information. The driver supports the AMD and Intel command set, though only the AMD command has been tested.
