This commit introduce SOC_MEM_NON_CONTIGUOUS_SRAM flag (that enebled for
esp32p4). If SOC_MEM_NON_CONTIGUOUS_SRAM is enabled:
- LDFLAGS+=--enable-non-contiguous-regions
- ldgen.py replaces "arrays[*]" from sections.ld.in with objects under
SURROUND keyword. (e.g. from linker.lf: data -> dram0_data SURROUND(foo))
- "mapping[*]" - refers to all other data
If SOC_MEM_NON_CONTIGUOUS_SRAM, sections.ld.in file should contain at
least one block of code like this (otherwise it does not make sense):
.dram0.bss (NOLOAD) :
{
arrays[dram0_bss]
mapping[dram0_bss]
} > sram_low
.dram1.bss (NOLOAD) :
{
/* do not place here arrays[dram0_bss] because it may be splited
* between segments */
mapping[dram0_bss]
} > sram_high
The size of partition of type APP should be multiple of 4 KB. Partition
generation tool now make this as a mandatory requirement. This is
minimum flash erase size. If the size of the APP type partition is not
aligned to 4 KB then the last erase operation could go beyond the allocated
partition and hence may fail. This issue would only be observed when the
firmware size grows very close to the allocated partition size, and hence
causing the OTA update to fail.
For already deployed devices on-field with the size of APP partition not
aligned to flash sector boundary, it is best to ensure that firmware
size always remains within the lower 4 KB boundary of the total
allocated space. While migrating to ESP-IDF 5.3 release, partition table
for an existing project can be adjusted accordingly for the build to
succeed.

This commit enables the standad VERSION argument for the project() macro
in ESP-IDF. The VERSION argument is compilant with the requirements of
cmake 3.16. This commit also adds new test cases for verifying the
validity of the version argument.

Previously, documentation sections that were only meant for multicore ESP
targets would use tags that depend on CONFIG_FREERTOS_UNICORE or
CONFIG_ESP_SYSTEM_SINGLE_CORE_MODE. This is not ideal as project configuration
can be changed by the user.
This commit updates those tags to use SOC_HP_CPU_HAS_MULTIPLE_CORES which is
always defined in multicore targets regardless of project configuration.
This extension allows running programs in QEMU similar to running
them on a real chip:
- 'idf.py qemu' — builds and runs the program in QEMU. User gets
a QEMU instance launched, and can work with it as a normal QEMU
instance.
- 'idf.py qemu monitor' — same, but QEMU is launched in the
background, and idf_monitor runs in the foreground, showing QEMU
output. Compared to only running 'idf.py qemu' this enables, for
example, automatic backtrace decoding.
- 'idf.py qemu gdb' — launches QEMU in the background and opens an
interactive GDB prompt, connecting it to QEMU.
- 'idf.py qemu --gdb monitor' and 'idf.py gdb' in another shell:
launches QEMU in the background, keeps it suspended until GDB is
connected, and opens idf_monitor. GDB can be used in another shell
to debug the application.
Many places in the ESP_SYSTEM are using CONFIG_FREERTOS_UNICORE instead of CONFIG_ESP_SYSTEM_SINGLE_CORE_MODE (GitHub PR)
