[U-Boot-Users] MPC8247 and others

[Glen Wolverton]

I ported u-boot to our custom board with an mpc8248 using the mpc8266ads
board as a starting point and adding to the mpc8260 cpu files.  There is
really not that much of a difference.

Hi !
We are developing a new board using the new MPC8247 processors from
Motorola.

You guys probably know this already :

MPC8247 is part of a new family of PowerQUICC II processors from
Motorola. This new family include MPC8247,MPC8248,MPC8271,MPC8272 which
are all derivatives from of the MPC8280 and MPC8260. 

Since I would like to post back patches and add support code for this
CPU back to the U-Boot project I was wondering what is best when
starting : Add a new directory to cpu, mpc8272 (or something) and
copying code from mpc8260 and changing this or add changes with defines
in the MPC8260 directory. The MPC8260 and MPC8247 are very similar but
there are some changes, configuration registers (HRCW is changed among
others
(start.S)) and an USB controller etc.

What is the best approach ?

Best regards
