 I wouldn't say "ARM PRU", that sounds as if the PRU is an ARM.

 I think
http://processors.wiki.ti.com/index.php/Programmable_Realtime_Unit_Software_Development
is  a much more useful URL.

 We prefer to specify a bit which license applies to which part. In addition,
the TSPA kind of eats up the other licenses, so I'd put it in front. You're also
missing a few licenses. Finally, the title of the non-standardized licenses
should be in full. So something like this:

TI_CGT_PRU_LICENSE = TI Technology and Software Publicly Available License
(compiler + PRU library), \
	Boost Software License 1.0 (compiler), \
 	BSD-2c, BSD-3c, MIT, Academic Free License 3.0, Hewlett-Packard (PRU library)

> +TI_CGT_PRU_LICENSE_FILES = PRU_Code_Generation_Tools_2.1.x_manifest.html

 Part of the license text is only in
PRU_CodeGen_Library_2.1_0222433C-30C1-442d-B5C6-2073BD97F80F.spdx.tag
