+Linux 2.6.x on MPC52xx family
+-----------------------------
+
+For the latest info, go to http://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 interesting 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.
