Prior to this commit, when calling:
- spi_timing_enter_mspi_low_speed_mode()
- spi_timing_enter_mspi_high_speed_mode()
psram timing is not tuned. This will lead to a stall during early
startup. This bug is on S3, for 80MHz DDR PSRAM
This commit will add psram timing tuning, in these two functions.
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
This commit gives basic mmu driver framework. Now it is able to maintain
mmu virtual address usage on esp32, esp32s2 and esp32s3. Usage to
external virtual address should rely on mmu functions to know which
address range is available, instead of hardcoded.
This commit also improves psram memory that is added to the heap
allocator. Now it's added to the heap, according to the memory
alignment.
