Are you basing the partition map on something or making it up?   
Clearly hrcw & u-boot are at fixed offsets, wondering about kernel &  
rootfs?

I'm making it up. From the brief look at the u-boot* git sources,
there is no `flashboot` yet, thus I'm free to make this up...

I've partitioned this flash based on these thoughts:

1. HRCW - whole sector, to not wear out it, plus it's impossible to
   create just 64 bytes partition;
2. Kernel - 2MB, should be enough for bootup kernels?
3. Rootfs - the rest up to...
4. U-Boot at the end.

I'm not saying that it's best map ever, I'm open to suggestions. ;-)

* Unfortunately I didn't look at the stock Freescale u-boot, maybe
  there was flashboot, most probably.. I'll find the CD to look this
  up.

Much thanks for noticing this,
