Versatile board is used as example to run u-boot under qemu. The patch fixes relocation for all versatile boards and adds a versatileqemu target to be used under qemu.
Thanks a lot!
Patch tested only under qemu, not on real boards. Tested with QEMU emulator version 0.14.50.
I've built u-boot tip with your patch with: make CROSS_COMPILE=arm-linux-gnueabi- O=$PWD/obj-versatileqemu \ versatileqemu_config make CROSS_COMPILE=arm-linux-gnueabi- O=$PWD/obj-versatileqemu -j3 using the Ubuntu (Linaro-based, 4.6.0-14ubuntu1cross1.52) armel cross-compiler but couldn't get this to start with my incantations of: qemu-system-arm -M versatilepb -kernel obj-versatileqemu/u-boot \ -m 128 -serial stdio and other combinations I've tried

and built with: make CROSS_COMPILE=arm-linux-gnueabi- O=$PWD/obj-qemuvexpressa9 \ qemuvexpressa9_config make CROSS_COMPILE=arm-linux-gnueabi- O=$PWD/obj-qemuvexpressa9 -j3 \ $PWD/obj-qemuvexpressa9/u-boot and this started fine with: qemu-system-arm -M vexpress-a9 -kernel obj-qemuvexpressa9/u-boot \ -m 1024 -serial stdio
I wonder whether it would make sense to use the same ifdef for versatile and vexpress boards (QEMU_NO_FLASH?) and prefix the board names with qemu; e.g. qemu_versatile_foo?
Could you share your recipe for getting the versatileqemu config to start? I'm using Ubuntu's qemu (Linaro-based, 0.14.50-2011.06-0-0ubuntu1).
Does this mean Stefano's patch will see a V2, or should I try and apply it as-is?
Amicalement,
