esp_ptr_in_rtc_iram_fast logic should be executed if
SOC_RTC_FAST_MEM_SUPPORTED is set but it should also be executed
if IRAM and DRAM region mapping is the same. Remove the
SOC_RTC_IRAM_LOW != SOC_RTC_DRAM_LOW part of the check.
Update heap component to use the modify function appropriately.
This commit fixes the issue when trying to allocate memory
with the MALLOC_CAP_EXEC in RTC memory. Prior to the fix,
the heap allocator was returning an address in RTC DRAM.
To fix this issue:
- modified memory_layout.c of the concerned targets to fill the iram_address
field in the rtc entry of the soc_memory_region array properly.
- modified heap component related functions to return IRAM address when
an allocation in RTC memory with MALLOC_CAP_EXEC is requested.
Closes https://github.com/espressif/esp-idf/issues/14835
The implicit promise of heap_alloc_caps() and friends is that the memory it
returns is fit for the purpose as requested in the caps field. Before
this commit, that did not happen; e.g. DMA-capable memory wass returned
from a correct region, but not aligned/sized to something the DMA subsystem
can handle.
This commit adds an API to the esp_mm component that is then used by the
heap component to adjust allocation alignment, caps and size dependent on
the hardware requirement of the requested allocation caps.
