[U-Boot-Users] RE: u-boot on Memec P4/7-FG456 (w/ virtex II pro)?

[jds]

to those of you who have ported uboot to the Virtex II PRO P4/7,
i have a nice, simple, straightforward question for you... :*)

what is your boot strategy?

do you load a minimal FPGA/uboot image (from flash) into the
internal RAM (~80KBytes big) and then in turn download the OS
and application code?
OR
do you have a very very simple FPGA/bootloader image which in
turn loads uboot into EXTERNAL RAM and then uboot loads the OS
and application code?
OR
yet some other way?

related to option 1 above...
does uboot for the the Virtex II PRO P4/7 fit nicely into the 80KB?

thanks for any insight.
