+ * ESP32-H2 cache profile counter units.
+ *
+ * Single cache level shared by instructions and data (the flash cache,
+ * 32-byte lines), with two request buses: bus0 carries instruction
+ * fetches, bus1 carries data accesses. There is one next-level counter
+ * per bus (no read/write split), mapped here to line_fills. The cache is
+ * read-only (no PSRAM, no write-back — see SOC_CACHE_WRITEBACK_SUPPORTED),
+ * so there are no write-back counters.
