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;
