+ * This assembly module provides a replica of OsmocomBB's bogo-millisecond
+ * delay_ms() function.  It is literally a copy of what OsmocomBB's delay_ms()
+ * compiles to with their gcc version and their optimization settings, as seen
+ * by doing arm-elf-objdump on their lib/delay.o.
+ *
+ * This hack is intended for those cases where we have to copy OsmocomBB's
+ * black magic voodoo operations with no ability to understand what is actually
+ * needed, such as SPCA552E initialization on the Pirelli DP-L10.
