<br><font size=2 face="sans-serif">Hi,</font><br><font size=2 face="sans-serif">I'm quite new to Open firmware, and
I apologize if my question sound silly or has been already answered.</font><br><br><font size=2 face="sans-serif">My system is PowerPC-based (8641D) and
has a 2-level PCI tree with a PCI-express switch in the middle, thus</font><br><font size=2 face="sans-serif">with many subordinate busses.</font><br><font size=2 face="sans-serif">Being it an embedded system, I was trying
to write the complete DTS for describing the structure for Linux to boot</font><br><font size=2 face="sans-serif">without having to patch the platform
code.</font><br><br><font size=2 face="sans-serif">Before doing so, I was asking myself
whether u-boot offers a runtime mechanism for filling the blob with the
complete snapshot</font><br><font size=2 face="sans-serif">of the PCI bus structure as discovered
by u-boot code before passing control to Linux.</font><br><font size=2 face="sans-serif">(at the moment I tftp a pre-compiled
blob that I'm trying to adapt starting from the MPC8641HPCN one, which
in fact has no PCI-2-PCI</font><br><font size=2 face="sans-serif">bridges in the middle).</font><br><br><font size=2 face="sans-serif">Thanks in advance!</font><br><br><font size=2 face="sans-serif">regards,</font><br><br><font size=2 face="sans-serif">luigi</font><br><br><font size=2 face="sans-serif">- - - - - - - - - - - - - - - - - -
