I'm a newbie in this field, and deal with an ARM946E based borad.

Note that ARMBoot is a dead project; deveoplment continues in the environment of the U-Boot project; followup set to the u-boot-users mailing list.

In my guess, there should have armboot, bzImage, & romfs in the flash.

No. bzImage does not work. You will have to use the "mkimage" tool to build a special U-Boot / ARMBoot image.

How are they arranged by address in the flash memory?

U-Boot must be locatewd such that it gets started when the CPU comes out of reset. On ARM this usually means that you will have to put it in flash such that it starts at physical address 0x0000. For the other images you can chose which addresses you want - it makes sense to align the images with the sectors of your flash memory, though.

Thanks for any information

You are welcome.
