-- gerrit commit 78debc14a535504ca4017013f65539ac5eb8e8b6 Author: Andrey Yurovsky <[email protected]> Date: Mon Mar 30 12:50:13 2015 -0700 flash: at91samd: add SAML21 support, fix part ID issue This adds support for the new Atmel SAML21 family of low-power Cortex M0+ devices. Their Flash controller is essentially the SAMDxx one so the change consists of adding the new part IDs. Unfortunately the device ID logic had a couple of mistakes in it that did not affect anything on SAMD2x devices (due to 0 values expected there) but that is a problem on L21, it's therefore addressed here and things should now match the datasheets. Tested on Amtel SAML21 Xplained Pro development kit against the included SAML21J18A there. Also tested for regressions on a SAMD20 and SAMD21 using their dev kits.
