-- gerrit commit 20c3f63513018bc94f47941f3bef8fca3a84dde6 Author: Spencer Oliver <[email protected]> Date: Thu Nov 1 11:19:29 2012 +0000 hla: add ability to configure read/write buffer size Other adapters (TI ICDI) that use this driver can use a larger read/write buffer size than the original stlink could.
