ZEPHYR_BASE and ZEPHYR_BUILD directories were passed to Sphinx via

the conf.py file itself. As a result, Sphinx is less dependent on CMake
to operate.

Because these two functions are called from threads and ISR.
And they run a bit-wise OR operation on the interrupt registers.
So protect them to prevent race condition between thread and ISR
context where causing an interrupt won't enable as expected.
eg.
- Pseudo code of thread enable IER1's bit1:
1. load word from IER1 (0x40) and write into CPU register S1
=> S1=0x40
2. Or S1's bit1
=> S1=0x42
(But if an interrupt is triggered here)
3. Store word to IER1 from S1
=> IER1=0x42
(IER1 will be 0x42 not 0x43, IER1's bit0 is disable again due to the
race condition above)
-Pseudo code of ISR enable IER1's bit0
1. load word from IER1 (0x40) write into CPU register S2
=> S2=0x40
2. Or S2's bit0
=> S2=0x41
3. Store word to IER1 from S2
=> IER1=0x41
4. Go back to thread.

So far the maximum configurable file size was limited to 16KB (2^14).
This might be enough for small partitions on internal flash. For
external QSPI memories however, this is certainly too restrictive.
Change maximum configurable file size to be 1GB, which is 2^30. Such
value will prevent signed integers overflow on 32-bit platforms, while
giving user full flexibility on how big log files should be.

rand() and srand() are pseudo-random number generator functions
defined in ISO C. This implementation uses the Linear Congruential
Generator (LCG) algorithm with the following parameters, which are the
same as used in GNU Libc "TYPE_0" algorithm.
Modulus 2^31
Multiplier 1103515245
Increment 12345
Output Bits 30..0
Note that the default algorithm used by GNU Libc is not TYPE_0, and
TYPE_0 should be selected first by an initstate() call as shown below.
All global variables in a C library must be routed to a memory
partition in order to be used by user-mode applications when
CONFIG_USERSPACE is enabled. Thus, srand_seed is marked as
such. z_libc_partition is originally used by the Newlib C library but
it's generic enough to be used by either the minimal libc or the
newlib.
All other functions in the Minimal C library, however, don't require
global variables/states. Unconditionally using z_libc_partition with
the minimal libc might be a problem for applications utilizing many
custom memory partitions on platforms with a limited number of MPU
regions (eg. Cortex M0/M3). This commit introduces a kconfig option
CONFIG_MINIMAL_LIBC_RAND so that applications can enable the
functions if needed. The option is disabled by default.
Because this commit _does_ implement rand() and srand(), our coding
guideline check on GitHub Action finds it as a violation.
Error: lib/libc/minimal/include/stdlib.h:45:WARNING: Violation to
rule 21.2 (Should not used a reserved identifier) - srand
But this is false positive.
The following is a simple test program for LCG with GNU Libc.
#include <stdio.h>
#include <stdlib.h>
int main()
{
static char state[8];
/* Switch GLIBC to use LCG/TYPE_0 generator type. */
initstate(0, state, sizeof(state));
srand(1); /* Or any other value. */
printf("%d\n", rand());
printf("%d\n", rand());
return 0;
}
See initstate(3p) for more detail about how to use LCG in GLIBC.
