Fixes minor issue with a trace (build failure with -Werror):
libelf/libelf_symbols.c:310:41: error: pointer of type 'void *' used in arithmetic [-Werror=pointer-arith]
310 | (uintptr_t)(sym->st_value + symbol->sym_value));
In SMP mode, if all cores start at same time, all from __start(),
then only primary need do initialize, so others core should wait
primary, use 'sev' let the non-primary continue to __cpuN_start().

The IDMA needs to have 32 bit word alignment, in fact it will
AND off the lower 2 bits of the value stored in IDMABASE0R.
This bug was masked by CONFIG_ARMV7M_DCACHE causing proper word alignment
and also FAT_DMAMEMORY being aligned.
This commit extends the unaligned logic (used for dcache) to take into account
the need for a buffer copy when the buffer is ot 32 bit word.
It leverages the fact that when CONFIG_ARMV7M_DCACHE is not defined the up_xxxxx_dcache are nops.
1. Don't handle invalid or empty pte entries
num_partition_entries field in GPT typically means number of maximum entries
and not the number of used entries. Empty entries are indentified with
"0" partition type guid. Loop through all the entries
2. Fix the GPT partition size calculation
"ending_lba" is included in the partition, it is not the start of the next one.
Thus the correct size of the partition is end-start+1

* boards/arm/tiva/tm4c129e-launchpad/README.txt:
Expand this documentation with information about: toolchains,
debugging (including the elusive openocd incantation to flash program
the board), MCU clocking, more details about the Virtual COM port
exposed via ICDI, and a description of the recently added ostest
configuration.
* boards/arm/stm32/b-g474e-dpow1/README.txt:
(Debugging): OpenOCD requires permissions for certain operations. The
preferred thing to do is to properly configure udev rules. The
expedient thing to do is to run it as root with 'sudo', but we do not
want to encourage that, as discussed earlier on this PR [1]. This
revised text offers a compromise where we mention both options, but
we talk about udev rules first and explicitly say that using 'sudo'
is not encouraged. We leave it up to developers to decide what is
best in their particular situation.

New file. Compared to b-g474e-dpow1:nsh, it adds the following
configs:
+CONFIG_BUILTIN=y
+CONFIG_NSH_BUILTIN_APPS=y
+CONFIG_TESTING_OSTEST=y
and, because ostest currently fails when priority inheritance is
enabled, it removes the following configs:
-CONFIG_PRIORITY_INHERITANCE=y
-CONFIG_PTHREAD_MUTEX_DEFAULT_PRIO_INHERIT=y
