M54455EVB with Rev. 1 silicon - will Linux 2.6.29 work properly?

Right now I'm working through a issue, and in the course of it, I recalled a passage from the M54455EVB BSP User's Manual, Rev 1.3, page 3-1:


This BSP is known to work on the following board(s) revision(s):

  • Baseboard: M54455EVB Rev D
  • CPU: M54455 Rev 2

Not knowing exactly how to identify the silicon revision (unsure if "Freescale MCF54455 (Mask:48 Version:1)" in U-Boot means Rev 1 silicon), I Googled and found the chip errata document, which shows that Rev 1 is marked "1M22H" and Rev 2 is "2M22H".


So I checked my (newly acquired) M54455EVB, and while the sticker on the board says "Rev. D", the chip itself is marked "1M22H", meaning that I've got Rev 1 silicon.


Do I have any hope of using the new(ish) Sep-2010 LTIB with Kernel 2.6.29 with this Rev 1 silicon, or do I need to ship my M54455EVB mainboard off for BGA rework to get Rev 2 silicon put on there?  Has anyone had any issues (or heck, any success) with running the 20100919 LTIB on an M54455EVB with Rev 1 silicon?
