+ * Startup code for IBM/AMCC PowerPC 4xx (PPC4xx) based boards
*
- * The processor starts at 0xfffffffc and the code is executed
- * from flash/rom.
- * in memory, but as long we don't jump around before relocating.
- * board_init lies at a quite high address and when the cpu has
- * jumped there, everything is ok.
- * This works because the cpu gives the FLASH (CS0) the whole
- * address space at startup, and board_init lies as a echo of
- * the flash somewhere up there in the memorymap.
+ * The following description only applies to the NOR flash style booting.
+ * NAND booting is different. For more details about NAND booting on 4xx
+ * take a look at doc/README.nand-boot-ppc440.
*
- * board_init will change CS0 to be positioned at the correct
- * address and (s)dram will be positioned at address 0
+ * The CPU starts at address 0xfffffffc (last word in the address space).
+ * The U-Boot image therefore has to be located in the "upper" area of the
+ * flash (e.g. 512MiB - 0xfff80000 ... 0xffffffff). The default value for
+ * the boot chip-select (CS0) is quite big and covers this area. On the
+ * 405EX this is for example 0xffe00000 ... 0xffffffff. U-Boot will
+ * reconfigure this CS0 (and other chip-selects as well when configured
+ * this way) in the boot process to the "correct" values matching the
+ * board layout.
