Problems building yocto for Xilinx ML507 (with some tentative fixes)

[Andrea Sterbini <a.sterbini@tiscali.it>]

Hi
I have just bought an old Xilinx ML507 and I am trying to build yocto, 
but I find some problems building the minimal image
I am a yocto newbie ... thus I wonder if I am missing something important.

My setup: Linux Fedora 18 64 bits

I hope I am following the correct procedure:
> git clone git://git.yoctoproject.org/poky
> cd poky
> git clone git://git.yoctoproject.org/meta-xilinx -b 
> master-xilinx-ml507-gcc-4.7 meta-xilinx
> git clone git://git.openembedded.org/meta-openembedded
> . oe-init-build-env

My bblayers contains
> BBLAYERS ?= " \
>   /home/andrea/src/FPGA/poky/meta \
>   /home/andrea/src/FPGA/poky/meta-yocto \
>   /home/andrea/src/FPGA/poky/meta-yocto-bsp \

>   /home/andrea/src/FPGA/poky/meta-xilinx \
>   /home/andrea/src/FPGA/poky/meta-angstrom \
>   "

My local.conf contains

The problems I have found (and someway fixed) are:

1) when I do "bitbake meta-toolchain" I get an error complaining that 
the compiler is not able to build for powerpc with FPU
Fix: I have changed the ml507 rules to include just the soft FPU

2) the libffi library version "3.0.12" has a small bug (a misplaced 
#ifndef), which is fixed in version "3.0.13"
Fix: I have added to my local.conf

> PREFERRED_VERSION_libffi = "3.0.13"
> PREFERRED_VERSION_libffi-native = "3.0.13"

This way the toolchain compiles properly

When I try "bitbake core-image-minimal" I get 2 problems:

1) the Xilinx git repository has moved from git.xilinx.com to 
github.com/Xilinx
Fix: I have changed the links in u-boot and linux-xilinx

2) bitbake complains about the license missing from the u-boot recipe
3) I have troubles also with the git.denx.de repository, which I can 
easily clone by hand but not by bitbake
Fix: I have added the required variables at the end (and fixed the git 
links)

There still some problems which stop my build ...
I will get them to you in a following email

All the best
