The options for
bwa index are :
Usage: bwa index [options] <in.fasta>
Options: -a STR BWT construction algorithm: bwtsw, is or rb2 [auto]
-p STR prefix of the index [same as fasta name]
-b INT block size for the bwtsw algorithm (effective with -a bwtsw) 
-6 index files named as <in.fasta>.64.* instead of <in.fasta>.*
The standard option for human and mouse would be
-a bwtsw, which creates indices based on the Burrows-Wheeler Transform (BWT).
Thus, to index your FASTA genome, you just need to do:
bwa-0.7.17/bwa index -a bwtsw mm10/mm10.fasta
