+
+   CONFIG_FASTBOOT_BUF_SIZE is defined in am6x_a53_snagfactory.config and specifies
+   the maximum buffer size for flashing files. Its value must be equal or greater
+   than the largest file size being flashed. If smaller, non-sparse images will
+   not flash correctly due to issues with chunked processing.
