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. In collabouration with: bde Tested by: andreast, nwhitehorn, jceel MFC after: 2 weeks

Convert Freescale PowerPC platforms to FDT convention.

2010-07-11T21:08:29Z

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. Reviewed by: imp Sponsored by: The FreeBSD Foundation

Move from using devclass_find_free_unit(cfi_diskclass, 0) to -1, since

they have the same basic behavior.

choose the size of the last region for d_stripsize instead of the first;

this fixes geom_redboot on boards that have multiple parts/regions as it uses the value to locate the FIS directory which is in the last erase region of flash

Add cfid, a disk interface to CFI flash devices; this enables construction

of flash-based filesystems. Note this is not interlocked against the raw CFI device.

fix building w/o CFI_ARMEDANDDANGEROUS

expand CFI_ARMEDANDDANGEROUS to include writing the user segment

of the PR; this register is actually write-once so deserves the safety-belt as much as the PLR

Add support for frobbing Intel StrataFlash Protection Registers:

2009-02-05T18:12:07Z

o add CFI_SUPPORT_STRATAFLASH compile option to enable support o add new ioctls to get/set the factory and user/oem segments of the PR and to get/set Protection Lock Register that fuses the user segment o add #defines for bits in the status register o update cfi_wait_ready to take an offset so it can be used to wait for PR write completion and replace constants w/ symbolic names Note: writing the user segment isn't correct; committing now to get review.
