All the partition handling API functions and data-types were moved from the 'spi_flash' component to the new one named 'esp_partition'. See Storage 5.x migration guide for more details
Some of the Memory Protection (internal) API functions dealing with per-CPU operations were missing appropriate handling of the CPU count actually configured by CONFIG_FREERTOS_UNICORE. The flaw was fixed across all the places found in the code as the issue was of general type
ESP32H2 doesn't support access to RTC memory through various buses, thus .rtc.dummy section
makes no sense here. The section is used for blind padding in LD script - to provide proper section offsets)
This bugfix contains 3 fixes:
1. .rtc_dummy section is removed (not needed for C3)
2. .rtc_text section is padded with 16B for possible CPU prefetch
3. .rtc_text section is aligned to 4B boundary to comply with PMS Memprot requirements
esp_restart()/panic_restart() never resets the Digital system (so far required only by the Memprot feature) as there's a typo in the corresponding #define:
it checks CONFIG_ESP_SYSTEM_CONFIG_MEMPROT_FEATURE instead of CONFIG_ESP_SYSTEM_MEMPROT_FEATURE.
Issue fixed.

When the application is being debugged it should check the call result (esp_cpu_in_ocd_debug_mode())
is not given volt.glitch attack - so the result is triple-checked by ESP_FAULT_ASSERT macro. In case
the check fails, the system is reset immediately

Too short timeouts often cause useless failures on large-capacity SDs (16GB+)
Fixed by adding 60 sec timeout on new "Filesystem mounted" checkpoint
JIRA IDF-3741
IRAM section didn't contain sufficient padding for possible CPU instruction prefetch,
ie instruction fetch could happen in DRAM section which is prohibited by the Memprot module.
This is fixed by adding 16B to the end of IRAM section in LD script (C3 CPU prefetch buffer depth is 4 words)
Closes IDF-3554
* fix
Check Memprot lock bit(s) during the system startup, abort/reset on any Memprot parts found locked during this phase.
There is no legal reason to disallow the Memprot configuration by the system, so it's either a critical bug in the
application or an malicious attempt to bypass the system security.
Error message is printed before digital system reset.
Closes IDF-2700
Software support for PMS module.
Allows controlled memory access to IRAM (R/W/X) and DRAM0 (R/W)
On/locked by default, configurable in Kconfig (esp_system)
