+ This patch enables the "new" get_dev() function for block devices

+ Hopefully we can resolve this relocation issue soon for all platform

+
+ [PATCH] PPC4xx: Add 440SP(e) DDR2 SPD DIMM support
+
+ This patch adds support for the DDR2 controller used on the
+ 440SP and 440SPe. It is tested on the Katmai (440SPe) eval
+ board and works fine with the following DIMM modules:
+
+ - Corsair CM2X512-5400C4 (512MByte per DIMM)
+ - Kingston ValueRAM KVR667D2N5/512 (512MByte per DIMM)
+ - Kingston ValueRAM KVR667D2N5K2/2G (1GByte per DIMM)
+
+ This patch also adds the nice functionality to dynamically
+ create the TLB entries for the SDRAM (tlb.c). So we should
+ never run into such problems with wrong (too short) TLB
+ initialization again on these platforms.

+ * The Xilinx SystemACE chip support is activated by defining

+ *
+ * The CONFIG_SYSTEMACE also adds to fat support the device class
+ * "ace" that allows the user to execute "fatls ace 0" and the
+ * like. This works by making the systemace_get_dev function
+ * available to cmd_fat.c:get_dev and filling in a block device
+ * description that has all the bits needed for FAT support to
+ * read sectors.
+ *
+ * According to Xilinx technical support, before accessing the
