Linux 2.6.x on MPC52xx family

For the latest info, go to https://www.246tNt.com/mpc52xx/

To compile/use :

  • U-Boot:

    # <edit Makefile to set ARCH=ppc & CROSS_COMPILE=... ( also EXTRAVERSION
       if you wish to ).
    # make lite5200_defconfig
    # make uImage
    
    then, on U-boot:
    => tftpboot 200000 uImage
    => tftpboot 400000 pRamdisk
    => bootm 200000 400000
    
  • DBug:

    # <edit Makefile to set ARCH=ppc & CROSS_COMPILE=... ( also EXTRAVERSION
       if you wish to ).
    # make lite5200_defconfig
    # cp your_initrd.gz arch/ppc/boot/images/ramdisk.image.gz
    # make zImage.initrd
    # make
    
    then in DBug:
    DBug> dn -i zImage.initrd.lite5200
    

Some remarks:

  • The port is named mpc52xxx, and config options are PPC_MPC52xx. The MGT5100 is not supported, and I’m not sure anyone is interested in working on it so. I didn’t took 5xxx because there’s apparently a lot of 5xxx that have nothing to do with the MPC5200. I also included the ‘MPC’ for the same reason.
  • Of course, I inspired myself from the 2.4 port. If you think I forgot to mention you/your company in the copyright of some code, I’ll correct it ASAP.
