[U-Boot-Users] AT91 Header File Clarification

I have a question about the arrangement of include files for the at91sam9 family.

Is the intention that asm/arch/at91_xxx.h be applicable for all at91sam9 microcontrollers, or should they be broken down into subarch folders (e.g. asm/arch/at91sam9261/at91_pmc.h)?

I am trying to bring up the at91sam9261 on a custom board a little ahead of what appears to be the schedule for the at91sam9261ek and I want to try to be compatible with the existing format. I haven't done a lot of comparisons between 9260/9261/9263, but for some things (e.g. at91_lcd.h) it obviously depends on which microcontroller you're using.

Thanks, Zac
