rtems/src/regiongetinfo.c, rtems/src/regiongetsegment.c,
rtems/src/regiongetsegmentsize.c, rtems/src/regionresizesegment.c,
rtems/src/regionreturnsegment.c: Restructed to move the OBJECTS_LOCAL
case to the top of the switch statement, have a single exit with one
call to _RTEMS_Unlock_allocator and eliminate the fall-through return
of RTEMS_INTERNAL_ERROR. These changes produced simplier assembly
code and allowed for complete test coverage.
* clock/ckinit.c, startup/bspstart.c: Eliminate the
clicks_per_microsecond field in the SuperH CPU Table and define
another mechanism for drivers to obtain this information.
* startup/bspstart.c: Eliminate the clicks_per_microsecond field in the
SuperH CPU Table and define another mechanism for drivers to obtain

sh7750/timer/timer.c: Eliminate the clicks_per_microsecond field in

the MIPS CPU Table and define another mechanism for drivers to obtain

* rtems/score/cpu.h: Eliminate the clicks_per_microsecond field in the
MIPS CPU Table and define another mechanism for drivers to obtain
this information.
* shared/console/uart.c: when draining UART during
initialization (wait for possible printk() activity
to finish) look at TEMT (fifo, holding-reg and shift-reg)
rather than THRE (fifo, holding-reg only). This resolved
some scrambled output issues for me.
Enhanced semantics: if BSP initializes BSPBaseBaud to a negative
value then the driver interprets the modulus as a speed value
and uses the current setting of the divisor to compute the
clock speed (BSPBaseBaud). This is useful if you have a board
that you know is initialized e.g., to 9600 but you
don't know the clock speed.
* Makefile.am, motorola_powerpc/Makefile.am,
* shared/pci/detect_raven_bridge.c, Makefile.am,
* shared/pci/generic_clear_hberrs.c: separated the generic
version of _BSP_clear_hostbridge_errors() into its own
file.
* libi2c/libi2c.c, libi2c/libi2c.h, libi2c/README_libi2c:
Added checks so that use of 'stdio' is avoided (falling
back to 'printk') before the system is up.
Publish driver entry points so that the libi2c driver could
be added to the applications 'device driver table'.
This is not fully implemented yet, though, since in addition to
initializing libi2c the low-level i2c bus drivers as well
as high-level i2c device drivers need to be registered
with the library.
Updated README_libi2c accordingly.
* libnetworking/rtems/rtems_glue.c: let rtems_bsdnet_ifconfig
(SIOCGIFMEDIA) pass the user parameter down to the ioctl
so that it knows what PHY they want to look at.
* rtems/score/powerpc.h: Added a '__ppc_generic' CPU variant.
The goal would be making cpukit and hopefully libcpu work
for all (or at least most) CPUs/BSPs with -D__ppc_generic so
that eventually all tests [#if defined(<cpu_flavor>)] for CPU
flavors can be eliminated.
