[U-Boot-Users] uboot and Pci in Pq2fads-ZU

	I am using a PQ2FADS-ZU board with u-boot.I have an option to change
jumpers and DIP Switches for setting the local bus to PCI mode.However
U-boot refuses proceed after Initialising DRAM.I went through the source and
initialises the LSDRAM after reading the BCSR.

Any pointers from the experts here would be really helpful.

Subject: [U-Boot-Users] autostart

HI !

 I have a problem with device initialisation in the kernel (all up and
 in u-boot) , so I wanted to have u-boot load the kernel, decompress it but 
 then not actually start it -  reading the u-boot manual I found that one 
 should use autostart no. The sequence I used was:

   setenv ipaddr
   setenv serverip
   tftpboot 0x350000 vmlinux.PPCBoot
   setenv autostart no 
   bootm 0x350000 

 but that simply kicks up the kernel and ends up in a panic becaues the 
 network and serial port initialization don't work in the kernel which I'm 
 trying to debug that - but I can't seem to stop the kernel with a
 as the xilinx tools (XMD) simply does not set it, so I wanted u-boot to
 at the kernel entry and step it from there - no luck though.

 So how can I get u-boot to just do the decompression but not pass control
 the kernel ?

thx !
