+commit 6bd2447ee47ee23c18d2b3c7ccd5a20f7626f5b3
+Author: Gary Jennejohn <garyj@pollux.denx.de>
+Date: Wed Jan 24 12:16:56 2007 +0100
+
+ Add port for the lpc2292sodimm evaluation board from EmbeddedArtists
+
+commit 2daf046ba627f85f44195815778140039636244e
+Author: Bartlomiej Sieka <tur@semihalf.com>
+Date: Tue Jan 23 17:22:06 2007 +0100
+
+ [iDMR] Add MTD and JFFS2 support, also add default partition definition.
+
+commit f7db33101fbc9c8f0a10738ce87034875a17aeb9
+Author: Bartlomiej Sieka <tur@semihalf.com>
+Date: Tue Jan 23 14:21:14 2007 +0100
+
+ [iDMR] Flash driver on initialisation write-protects some sectors,
+ currently sectors 0-3. Sector 3 does not need to be protected, though
+ (U-boot occupies sectors 0-1 and the environment sector 2). This commit
+ fixes this, i.e., only sectors 0-2 are protected.
+
+commit 0ed47bb119cd2c4c16edb2548789148f9e6dc9de
+Author: Bartlomiej Sieka <tur@semihalf.com>
+Date: Tue Jan 23 14:11:22 2007 +0100
+
+ [iDMR] Using MII-related commands on iDRM board doesn't work now (e.g.,
+ "mii device" results in "Unexpected exception"). Fixing this properly
+ requires some clean-up in the FEC drivers infrastructure for ColdFire, so
+ this commit disables MII commads for now.
+
+commit 363d1d8f9c99b63daef81f5985cab3fc00edde5c

+Date: Tue Jan 23 13:25:22 2007 +0100
+
+ [ColdFire MCF5271 family] Add CPU detection based on the value of Chip
+ Identification Register (CIR).
