This directory contains the source code for U-Boot, a boot loader for
-Embedded boards based on PowerPC and ARM processors, which can be
-installed in a boot ROM and used to initialize and test the hardware
-or to download and run application code.
+Embedded boards based on PowerPC, ARM, MIPS and several other
+processors, which can be installed in a boot ROM and used to
+initialize and test the hardware or to download and run application
+code.
The development of U-Boot is closely related to Linux: some parts of
the source code originate in the Linux source tree, we have some

- CPU Module Type: (if CONFIG_COGENT is defined)
Define exactly one of
supported (PIP405, MIP405, MPC5200); define
CONFIG_USB_UHCI to enable it.
define CONFIG_USB_KEYBOARD to enable the USB Keyboard
- end define CONFIG_USB_STORAGE to enable the USB
+ and define CONFIG_USB_STORAGE to enable the USB
storage devices.
Note:
Supported are USB Keyboards and USB Floppy drives
function struct part_info* jffs2_part_info(int part_num)
If you define only one JFFS2 partition you may also want to
- #define CFG_JFFS_SINGLE_PART 1
+ #define CFG_JFFS_SINGLE_PART 1
to disable the command chpart. This is the default when you
have not defined a custom partition
source code. It is used to make hardware dependant
initializations.
-- CFG_IMMR: Physical address of the Internal Memory Mapped
- Register; DO NOT CHANGE! (11-4)
- [MPC8xx systems only]
+- CFG_IMMR: Physical address of the Internal Memory.
+ DO NOT CHANGE unless you know exactly what you're
+ doing! (11-4) [MPC8xx/82xx systems only]
- CFG_INIT_RAM_ADDR:
Add the "loopw" memory command. This only takes effect if
the memory commands are activated globally (CFG_CMD_MEM).
+- CONFIG_MX_CYCLIC
+ Add the "mdc" and "mwc" memory commands. These are cyclic
+ "md/mw" commands.
+ Examples:
+
+ => mdc.b 10 4 500
+ This command will print 4 bytes (10,11,12,13) each 500 ms.
+
+ => mwc.l 100 12345678 10
+ This command will write 12345678 to address 100 all 10 ms.
+
+ This only takes effect if the memory commands are activated
+ globally (CFG_CMD_MEM).
