esp32: Allow SPIRAM_MALLOC_RESERVE_INTERNAL to span multiple regions of memory
...
- Allocate this pool after main_task is running, so it can use startup stack RAM
- Raise the maximum allowed value in KConfig to 256KB
- Based on forum discussions https://esp32.com/viewtopic.php?f=2&t=6550&sid=76cd27bda76c6d0e83d3fcc9ec30c650&start=10#p28253

spiram: expose function to initialize SPI RAM cache
...
Some frameworks based on ESP-IDF need to be able to decide whether to
initialize SPI RAM after the application has started. This change splits
out part of esp_spiram_init which manipulate cache MMU into a separate
function. Applications can disable cache, call esp_spiram_init_cache,
re-enable cache, and then call esp_spiram_init.
Disabling and re-enabling the cache can be achieved using functions
provided in esp_spi_flash.h.

Add initial SPI RAM support. This adds support for an ESP-PSRAM32 chip connected to the default flash pins and GPIO 16 and 17. The RAM is mapped to address 0x3F800000, but otherwise ignored by esp-idf as of yet.
