*
* A gpio is required for tck, tms, tdi and tdo. One or both of srst and trst
* must be also be specified. The required jtag gpios are specified via the
- * sysfsgpio_jtag_nums command or the relevant sysfsgpio_XXX_num commang.
+ * sysfsgpio_jtag_nums command or the relevant sysfsgpio_XXX_num commands.
* The srst and trst gpios are set via the sysfsgpio_srst_num and
* sysfsgpio_trst_num respectively. GPIO numbering follows the kernel
* convention of starting from 0.
