Subject: [PATCH] at91: at91sam9g45 family: identify several chip versions
Date: Mon, 21 Sep 2009 12:40:01 +0200 [thread overview]
Message-ID: <1253529601-15474-1-git-send-email-nicolas.ferre@atmel.com> (raw)
cpu_is_xxx() macros are identifying generic at91sam9g45 chip. This patch adds
the capacity to differentiate Engineering Samples and final lots through the
inclusion of at91_cpu_fully_identify() and the related chip IDs with chip
version field preserved.
