Add common (with Linux) MTD partition scheme and "mtdparts" command
Old, obsolete and duplicated code was cleaned up and replace by the new partitioning method. There are two possible approaches now: * define a single, static partition * use mtdparts command line option and dynamic partitioning Default is static partitioning.

Changes for U-Boot 1.1.3:
======================================================================
+* Add common (with Linux) MTD partition scheme and "mtdparts" command
+
+ Old, obsolete and duplicated code was cleaned up and replace by the
+ new partitioning method. There are two possible approaches now:
+
+ The first one is to define a single, static partition:
+
+ #undef CONFIG_JFFS2_CMDLINE
+ #define CONFIG_JFFS2_DEV "nor0"
+ #define CONFIG_JFFS2_PART_SIZE 0xFFFFFFFF /* use whole device */
+ #define CONFIG_JFFS2_PART_SIZE 0x00100000 /* use 1MB */
+ #define CONFIG_JFFS2_PART_OFFSET 0x00000000
+
+ The second method uses the mtdparts command line option and dynamic
+ partitioning:
+
+ /* mtdparts command line support */
+ #define CONFIG_JFFS2_CMDLINE
+ #define MTDIDS_DEFAULT "nor1=zuma-1,nor2=zuma-2"
+ #define MTDPARTS_DEFAULT "mtdparts=zuma-1:-(jffs2),zuma-2:-(user)"
+
+ Command line of course produces bigger images, and may be inappropriate
+ for some targets, so by default it's off.
+
* Fix build problems for PM856 Board
* Fix sign extension bug in 'fpga loadb' command;
