I've just started working on s/w for an 8555E-based board. On the 8555E I will be using the TSECs (Gigabit ethernet interfaces), DMA engines, the security engine, UARTs, DDR and Local Bus controllers and that's about it.
Right now I've got an MPC8560ADS eval board to test against. This board came with a 2.4.26-based kernel; it boots ok and runs the basic apps fine, however I haven't yet had an opportunity to exercise the wide array of functionality on the chip, so I don't know what gotchas or porting difficulties I might meet ahead.
Based on that, what kernel version/tree would you recommend? Should I stick with what I've got, move to a ppc-specific 2.4 tree, or jump to 2.6.x? Are there performance/features vs. stability tradeoffs I should be warned of?
Thanks in advance for any thoughts you may have.

Kylo,
All active development for PPC (including the MPCE8555E) is being done=20=
in 2.6 only at this point. I would recommend using 2.6.11 as a=20
starting point. Any code to support new features of the MPC8555E will=20=
be developed for 2.6 at this point.
The 2.6.11 tree has support for both the MPC8560 ADS board=20
(mpc8560_ads_defconfig) and the MPC8555 CDS board=20
(mpc8555_cds_defconfig). Those should be good starting points for any=20=
work you are doing.
