[U-Boot-Users] Is it easy to config BR1/OR1 as SDRAM in u-boot?

Hi, friends,

I am new to this forum.

Currently we are working on u-boot for our customized board (use MPC8272). Our reference board is mpc8272ads board from freescale. U-boot configiures mpc8272ads board as one of the mpc8260ads family. And u-boot uses BR0/OR0, BR1/OR1 for flash and BR2/OR2, BR3/OR3 for SDRAM. However, our customized board is configured using CS1 (BR1/OR1) for the SDRAM.

How can I modify the u-boot source code for the mpc8260ads family to let u-boot recognize BR1/OR1 as SDRAM? I don't know how many files will be related to this change and how 'deep' I will go.

or let the hardware engineer change SDRAM to CS2 (BR2/OR2) may be easier?

Thank you for your advice,
