+ * Text-heap allocator for the RP2350.
+ *
+ * Dynamically loaded code (e.g. a "lifted arm" copied in from NFS) must be
+ * placed in memory that the CPU can both write and then execute.  On the
+ * RP2350 the on-chip SRAM (0x20000000) is normal, executable memory, and
+ * this port runs without the MPU enabled (CONFIG_ARM_MPU=n), so RAM is not
+ * marked no-execute.  The general-purpose kernel heap therefore already
+ * satisfies the requirements of a text heap, and these wrappers simply
+ * forward to it (the same approach used by arch/arm/src/cxd56xx).
+ *
+ * Because the instruction and data views of this memory are the same
+ * address, ARCH_HAVE_TEXT_HEAP_SEPARATE_DATA_ADDRESS is not selected and
+ * up_textheap_data_address() is not required.
