the correct circumstances of DMA buffer size, serial
line interrupts, and ethernet interrupts the termios osend routine would
lock up waiting for the raw output buffer semaphore.

a BSP (c4xsim) supporting the simulator included with gdb. This port
was done by Joel Sherrill and Jennifer Averett of OAR Corporation.
Also included with this port is a space/time optimization to eliminate
FP context switch management on CPUs without hardware or software FP.
An issue with this port was that sizeof(unsigned32) = sizeof(unsigned8)
on this CPU. This required addressing alignment checks and assumptions
as well as fixing code that assumed sizeof(unsigned32) == 4.

now is an implementation of the prototypes in rtems/rtems/cache.h.
The libcpu/i386/wrapup directory is no longer needed.
The PowerPC needs this done to it.

<charles.gauthier@iit.nrc.ca>, and Darlene A. Stewart
<Darlene.Stewart@nrc.ca> to add support for a number of very
significant things:
+ BSPs for many variations on the Motorola MBX8xx board series
+ Cache Manager including initial support for m68040
and PowerPC
+ Rework of mpc8xx libcpu code so all mpc8xx CPUs now use
same code base.
+ Rework of eth_comm BSP to utiltize above.
John reports this works on the 821 and 860

substantial upgrade of newlibc.c occurred. Now the user extension
data area is used rather than notepads and as many routines as possible
were split into other files further reducing the minimum footprint
of an RTEMS executable.

unnecessarily uses any variables defined by the BSP. On this
sweep, use of BSP_Configuration and Cpu_table was eliminated.
A significant part of this modification was the addition of
macros to access fields in the RTEMS configuration structures.
This is necessary to strengthen the division between the BSP independent
parts of RTEMS and the BSPs themselves. This started after
comments and analysis by Ralf Corsepius <corsepiu@faw.uni-ulm.de>.

I'm working on code to mount my host based file system on the base file
system (imfs) and have a suggestion for a change to eval.c in the
c/src/lib/libc directory of the 8/20/1999 snapshot. The current version
does not test the result value returned from the evalpath callback (line 47)
in the case where follow_link is true. Attached is my suggested change.
Without this test the node_type callback may be called after evalpath
failed. node_type could set the type to some value other then
RTEMS_FILESYSTEM_HARD_LINK or RTEMS_FILESYSTEM_SYM_LINK but it seems cleaner
to add the check on result.

Here is another fix, which addresses a few more or less severe bugs in
configuration and unix/posix:
* Configuration fix: c/src/lib/configure.in didn't handle RDBG correctly
* Configuration fix: make depend was non-functional in
c/src/lib/libc/Makefile.in
* Configuration fix: stray comment removed from aclocal/target.m4
* RTEMS fix: termios support for unix/posix now uses the host's headers
only (was completely broken).
- Don't install RTEMS's newlib sys/termios.h for unix (sys/termios.h
apparently is a newlib specific header)
- To be able to compile RTEMS's termios.c with glibc2.1, glibc-2.1
needs __USE_MISC, which is a private define from gcc's features.h, being
defined only when _BSD_SOURCE of _SVID_SOURCE is defined. RTEMS's
termios apparently implements BSD, thus -D_BSD_SOURCE was added to
Linux-posix.cfg.
- Conflicting definitions for __USE_MISC and _BSD_SOURCE inside of
RTEMS codes removed due to definition of _BSD_SOURCE on the toplevel.
This fix has been tested with linux/posix (primary glibc2.1 native),
linux/posix (secondary libc5 native), sh/gensh1, i386/pc386 and a couple
of other bsp's/CPU.
To apply:
cd <srcdir>
patch -p1 < rtems-rc-19990709-9.diff
and
aclocal -I aclocal && automake && autoconf
cd c/src/lib; autoconf
or
./autogen

mount() was changed to avoid the use of a string as the options.

for simplicity.
