Hi all,
I don't kown if there is a function in u-boot to change the bus mode. The arm processor can work in sync mode, async mode and fast mode. To change in async mode you must write the cp15 register. This is useful for board that has slow memory access and it must be done by the bootloader.
Regards Michael

Hi For the AT91RM9200 cpu (which has an arm920t core) this is being done in lowlevel_init.S.
