These changes were obtained by running a script created by
Ulf Magnusson <Ulf.Magnusson@nordicsemi.no> for the following
specification:
1. Read the contents of all dts_fixup.h files in Zephyr
2. Check the left-hand side of the #define macros (i.e. the X in
#define X Y)
3. Check if that name is also the name of a Kconfig option
3.a If it is, then do nothing
3.b If it is not, then replace CONFIG_ with DT_ or add DT_ if it
has neither of these two prefixes
4. Replace the use of the changed #define in the code itself
(.c, .h, .ld)
Additionally, some tweaks had to be added to this script to catch some
of the macros used in the code in a parameterized form, e.g.:
- CONFIG_GPIO_STM32_GPIO##__SUFFIX##_BASE_ADDRESS
- CONFIG_UART_##idx##_TX_PIN
- I2C_SBCON_##_num##_BASE_ADDR
and to prevent adding DT_ prefix to the following symbols:
- FLASH_START
- FLASH_SIZE
- SRAM_START
- SRAM_SIZE
- _ROM_ADDR
- _ROM_SIZE
- _RAM_ADDR
- _RAM_SIZE
which are surprisingly also defined in some dts_fixup.h files.
Finally, some manual corrections had to be done as well:
- name##_IRQ -> DT_##name##_IRQ in uart_stm32.c

Nios2 is trying to use global pointer register to access variables
smaller than 8 bytes. GPR range is limited to 64 bytes and apparently
does not handle well variables placed in custom sections.
Current workaround is to increase logger structures (const and dynamic)
size (+8 bytes for dynamic, +4 bytes for constant). Then GPR is not
used and application can be linked. The downside is increase of memory
usage:
- ROM: <num_of_log_modules>*4 bytes
- RAM: <num_of_log_modules>*8 bytes (if runtime filtering is enabled)

Changed LOG_MODULE_REGISTER and LOG_MODULE_DECLARE macros to take log
level as optional parameter. LOG_MODULE_DECLARE can now also be used
in static inline functions in headers. Added LOG_LEVEL_SET macro
which is used when instance logging API is used to indicate maximal
log level compiled into the file.

.gnu.linkonce is an internal undocumented ld feature.
Just use __weak, which does the same thing we want.
This is only done for _sw_isr_table. _irq_vector_table
is left alone due to unwanted interactions between
__weak and the ld KEEP() directive.

We now place the linker directives for the SW ISR table
in the common linker scripts, instead of repeating it
everywhere.
The table will be placed in RAM if dynamic interrupts are
enabled.
A dedicated section is used, as this data must not move
in between build phases.

If dynamic interrupts are enabled, a set of trampoline stubs
are generated which transfer control to a common dynamic
interrupt handler function, which then looks up the proper
handler and parameter and then executes the interrupt.
Based on the prior x86 dynamic interrupt implementation which
was removed from the kernel some time ago, and adapted to
changes in the common interrupt handling code, build system,
and IDT generation tools.
An alternative approach could be to read the currently executing
vector out of the APIC, but this is a much slower operation.

In the past the capability to install interrupts at runtime was
removed due to lack of use-cases for Zephyr's intended targets.
Now we want to support hypervisor applications like ACRN where
virtual devices are presented to the kernel using PCI enumeration,
and the interrupt configuration is not known at build time.

This commit contributes a patch to the Arm Cortex-M linker
script, which guarantees that the linker sections for shared
memory and the application memory will have sufficient padding
in between, so that the latter will start from an address that
is 32-byte aligned. This is required for ensuring that the MPU
regions defined using the start and end addresses of the two
sections will not overlap. The patch targets ARMv8-M MPU with
no requirement for power-of-two alignment and size.

Tty device gets only read/write calls, but console retains
getchar/putchar for convenience.
Signed-off-by: Paul Sokolovsky <paul.sokolovsky@linaro.org>
Previously, transmit was effectively non-blocking - a character either
went into buffer, or -1 was returned. Now it's possible to block if
buffer is full. Timeout is K_FOREVER by default, can be adjusted
with tty_set_tx_timeout() (similar to receive timeout).
Signed-off-by: Paul Sokolovsky <paul.sokolovsky@linaro.org>
This allows to specify receive timeout, instead of previously
hardcoded K_FOREVER value. K_FOREVER is still the default, and can
be changes after tty initialization using tty_set_rx_timeout() call,
and timeout is stored as a property of tty. (Instead of e.g. being
a param of each receive call. Handling like that is required for
POSIX-like behavior of tty).

All the handling of POSIX file descriptors is now done by fdtable.c.
fs.c still manages its own table of file structures of the underlying
fs lib.
Signed-off-by: Paul Sokolovsky <paul.sokolovsky@linaro.org>
The table allows to wrap read/write (i.e. POSIX-compatible) semantics
of any I/O object in POSIX-compatible fd (file descriptor) handling.
Intended I/O objects include files, sockets, special devices, etc.
The table table itself consists of (underlying obj*, function table*)
pairs, where function table provides entries for read(), write, and
generalized ioctl(), where generalized ioctl handles all other
operations, up to and including closing of the underlying I/O object.

k_poll_signal was being used by both, struct and function. Besides
this being extremely error prone it is also a MISRA-C violation.
Changing the function to contain a verb, since it performs an action
and the struct will be a noun. This pattern must be formalized and
followed and across the project.
