Notepads where a feature of RTEMS' tasks that simply functioned in
the same way as POSIX keys or threaded local storage (TLS). They were
introduced well before per task variables, which are also deprecated,
and were barely used in favor of their POSIX alternatives.
In addition to their scarce usage, Notepads took up unnecessary memory.
For each task:
- 16 32-bit integers were allocated.
- A total of 64 bytes per task per thread.
This is especially critical in low memory and safety-critical applications.
They are also defined as uint32_t, and therefore are not guaranteed to
hold a pointer.
Lastly, they are not portable solutions for SMP and uniprocessor systems,
like POSIX keys and TLS.
updates #2493.
Add rtems_interrupt_local_disable|enable() as suggested by Pavel Pisa to
emphasize that interrupts are only disabled on the current processor.
Do not define the rtems_interrupt_disable|enable|flash() macros and
functions on SMP configurations since they don't ensure system wide
mutual exclusion.
Deprecate Classic API Notepads. Mark task_set/get_note() with
the deprecated attribute, and also mark the notepads field.
Replace disable with enable option for notepads in confdefs.h,
and make notepads disabled by default. The previous option
CONFIGURE_DISABLE_CLASSIC_API_NOTEPADS is now unused and
will emit a compile-time warning. A new option
CONFIGURE_ENABLE_CLASSIC_API_NOTEPADS is available to turn
on notepads, but it also will emit a compile-time warning
to indicate that notepads are deprecated.
Closes#2265
There is an issue linking dl0* which has not been resolved.
This issue is being tracked but is not considered a release
blocker. This patch is a workaround which disables libdl
for the v850 until the ticket is resolved.

Remove miniIMFS. Statically initialize the root IMFS.
Add configuration options to disable individual
features of the root IMFS, e.g.
o CONFIGURE_IMFS_DISABLE_CHOWN,
o CONFIGURE_IMFS_DISABLE_FCHMOD,
o CONFIGURE_IMFS_DISABLE_LINK,
o CONFIGURE_IMFS_DISABLE_MKNOD,
o CONFIGURE_IMFS_DISABLE_MOUNT,
o CONFIGURE_IMFS_DISABLE_READLINK,
o CONFIGURE_IMFS_DISABLE_RENAME,
o CONFIGURE_IMFS_DISABLE_RMNOD,
o CONFIGURE_IMFS_DISABLE_SYMLINK,
o CONFIGURE_IMFS_DISABLE_UNMOUNT, and
o CONFIGURE_IMFS_DISABLE_UTIME.
The dummy.c was a de-facto default configuration. Rename it to
default-configuration.c. Use unlimited objects and the stack checker.
This makes it easier for new RTEMS users which will likely use this file
if they just work with the usual main() function as the application
entry point. Provide proper arguments for main() using the BSP command
line. Add spare user extensions and drivers.
Do not initialize the network by default. Delete bspinit.c.
The LEON3 BSP have support for up to 8 termios consoles, the
LEON3-FT GR712RC uses 6 UARTs.
This does not take into account the BSP maximum devices instead
it is hardcoded to 6. This patch increases it the maximum
devices of DEVFS04 from 6 to 10.
posix_memalign() is prototyped to take a non-NULL parameter. But our
test is deliberately passing one in. With the -Wnon-null warning flag
enabled, we will always get warnings on this test unless we disable
that warning for this single test case.
