- to acknowledge the unused DCACHE added to DRAM for ESP32-S3 - For ESP32-S3, when the DCACHE size is set to 16 kB, the unused 48 kB is added to the heap in 2 blocks of 32 kB (from 0x3FCF0000) and 16 kB (from 0x3C000000). - But, if we try allocating memory from the 16 kB block and run an `esp_ptr_internal` check on that memory pointer, it fails as the address block from 0x3C000000 corresponds to the external memory symbols SOC_DROM_LOW and SOC_EXTRAM_DATA_LOW. (E.g. freertos - If the IDLE task stack buffer gets allocated from this region, the firmware will abort due to this failure). - Thus, the checks `esp_ptr_internal`, `esp_ptr_in_drom` and `esp_ptr_byte_accessible` have been updated to acknowledge this memory as a part of the DRAM.

esp_hw_support
This component contains hardware-related operations for supporting the system. These operations
are one level above that of hal in that these(1) use system services such as memory allocation, logging, scheduling
or (2) may be multi-step operations involving/affecting multiple parts of the SoC.
Implementations that don't fit other components cleanly, but are not worth creating a new component for (yet) may also be placed here as long as they don't pull dependencies other than the core system components.
