- * transport, and focusses on memory mapped resources as defined by the
+ * transport, and focuses on memory mapped resources as defined by the
* CoreSight architecture.
*
* A key concept in ADIv5 is the Debug Access Port, or DAP. A DAP has two
* is set in the DP_CTRL_STAT register, the SSTICKYORUN status is set and
* further AP operations will fail. There are two basic methods to avoid
* such overrun errors. One involves polling for status instead of using
- * transaction piplining. The other involves adding delays to ensure the
+ * transaction pipelining. The other involves adding delays to ensure the
* AP has enough time to complete one operation before starting the next
* one. (For JTAG these delays are controlled by memaccess_tck.)
