Leonoid,
I am working on a similar project: Avnet Virtex 4 mini-module configured with MPMC2 to 64Mb of x16 DDR OPB EMC to 4Mb x16 linear flash OPB to UARTLITE PLB to TEMAC
I also would like uartlite and temac drivers for both u-boot and linux 2.6.xx. Where did you get to? I am also considering the GSRD, but right now I just want to get a bootloader working
My boot sequence (planned) step 1 Hardware and initial bootloader (executing from BRAM, later from cache ALA Ultra Controller?) placed in platform flash Load U-boot to memory, or jump to U-boot in flash?
step 2 Load linux image from either flash or from TFTP server
What is assumed by the existing drivers in terms of interrupts and DMA?

Hi:
I'm porting u-boot on Vertex-4 based board (with PPC405 inside); I'm trying use ml403 u-boot as example. I have first stage boot loader, taking my u-boot image from serial and loading it to SDRAM, u-boot is configured to boot from main memory.
Several questions:
- I'm using ELDK 3.1.1 as crosstool; which target should I choose:
ppc_4xxFP or ppc_4xx?
- My board unlike ML403 has UARTLITE for serial interface. Can I use
serial_xuartlite.c from microblaze directory?
Thanks,
Leonid.
