Hi ML,
I'm evaluating the qemu-mips to simulate a mips 4kec/24kec board. I'm working on the high level booting sequence (linux init scripts), and qemu+uboot should be a good choice to emulate a basic system (flash + dram + 4kec cpu).
Furthermore, also following the doc/README.qemu_mips, I'm not able to see the u-boot prompt on my qemu because the flash is not recognized. I haven't experience with qemu-mips and I don't understand where the flash is placed (canonical 0xbfxxxx address?) and how it is managed. Reading the configs/qemu_mips.h, It seems that the flash is managed as a common CFI flash placed to 0xbfc00000 address... but u-boot shows always "Unknown FLASH on Bank 1" on startup.
Has anyone tried to use qemu-mips to boot a standard u-boot image (qemu_mips target on u-boot)?
Thanks for any suggestion.

This is the qemu banner (on Ubuntu 8.10):
EMU PC emulator version 0.9.1, Copyright (c) 2003-2008 Fabrice Bellard
Please use the SVN version of qemu for the current u-boot version
I'll update the README.qemu_mips to specify the last u-boot version for the old qemu
