 the recommended RISC-V bootflow: U-Boot SPL (M-mode) loads OpenSBI fw_dynamic
 firmware and U-Boot proper (S-mode), using the standard -bios functionality.
 
+Machine-specific options
+------------------------
+
+The following machine-specific options are supported:
+
+- aclint=[on|off]
+
+  When this option is "on", ACLINT devices will be emulated instead of
+  SiFive CLINT. When not specified, this option is assumed to be "off".
