## Summary * esp32s3/elf: Enable ELF loader for ESP32-S3 Provide `up_copy_section` function that enables copying data using the data bus. If the memory destination address is accessible through the instruction bus, the data is copied using the correspondent address accessible through the data bus. * binfmt/libelf: Enable ELF loader if text heap read is word-aligned The ELF loader needs to load the app into the memory before executing it from the same location. As expected, this memory space should be able to execute code. For architectures containing data and instruction buses, the instruction bus may not be able to be accessed in a non-aligned way, which is usually required when copying data to that location. Eventually, this same memory space can be accessed through the data bus, using different address ranges. This commit enables accessing the memory through the data bus to copy the app's data before executing it when `CONFIG_ARCH_HAVE_TEXT_HEAP_WORD_ALIGNED_READ` is enabled. ## Impact Enable ELF loader for ESP32-S3. ## Testing Internal CI testing + ESP32-S3-DevKitC-1 v1.0 -- This is an automated message from the Apache Git Service.
