at91: at91sam9g45 family: identify several chip versions
Nicolas Ferre [Mon, 21 Sep 2009 10:03:56 +0000 (12:03 +0200)]
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.
