+Changes since U-Boot 0.2.1:
+======================================================================
+
+* Patch by Stefan Roese, 18 Feb 2003:
+  CPCIISER4 configuration updated.
+
+* Patch by Stefan Roese, 17 Feb 2003:
+  Fixed bug in ext. serial clock setup on PPC405 (since PPC440 port).
+
+* Patch by Stefan Roese, 13 Feb 2003:
+  Add "pcidelay" environment variable (in ms, enabled via
+  CONFIG_PCI_BOOTDELAY).
+  PCI spec 2.2 defines, that a pci target has 2^25 pci clocks after
+  RST# to respond to configuration cycles (33MHz -> 1s).
+
+* Patch by Stefan Roese, 10 Feb 2003:
+  Add support for 4MB and 128MB onboard SDRAM (cpu/ppc4xx/sdram.c)
+
+* Add dual ethernet support on PM826
+
+* Add support for LXT971 PHY on PM826
+
+* Patch by Tord Andersson, 16 Jan 2003:
+  Fix flash sector count for TQM8xxL
+
+* Fix I2C EEPROM problem on ICU862 board (would only write the first
+  16 bytes out of each 32 byte block)
+
+======================================================================
+Changes for U-Boot 0.2.1:
+======================================================================
+
+* Add support for V37 board
+  (patch by Jón Benediktsson, 11 Dec 2002)
+
+* Update baudrate in bd_info when it gets changed
+
+* Add watchdog trigger points while waiting for serial port
+  (so far only 8xx -- needed on LWMON with 100ms watchdog)
+
+* Improve command line tool to access the U-Boot's environment
+  (figuration of the utility, using a config file)
+
+* Add single quote support for (old) command line parser
+
+* Switch LWMON board default config from FRAM to EEPROM;
+  in POST, EEPROM shows up on 8 addresses

+More About U-Boot Image Types:
+------------------------------
+
+U-Boot supports the following image types:
+
+   "Standalone Programs" are directly runnable in the environment
+  	provided by U-Boot; it is expected that (if they behave
+  	well) you can continue to work in U-Boot after return from
+  	the Standalone Program.
+   "OS Kernel Images" are usually images of some Embedded OS which
+  	will take over control completely. Usually these programs
+  	will install their own set of exception handlers, device
+  	drivers, set up the MMU, etc. - this means, that you cannot
+  	expect to re-enter U-Boot except by resetting the CPU.
+   "RAMDisk Images" are more or less just data blocks, and their
+  	parameters (address, size) are passed to an OS kernel that is
+  	being started.
+   "Multi-File Images" contain several images, typically an OS
+  	(Linux) kernel image and one or more data images like
+  	RAMDisks. This construct is useful for instance when you want
+  	to boot over the network using BOOTP etc., where the boot
+  	server provides just a single image file, but you want to get
+  	for instance an OS kernel and a RAMDisk image.
+  
+  	"Multi-File Images" start with a list of image sizes, each
+  	image size (in bytes) specified by an "uint32_t" in network
+  	byte order. This list is terminated by an "(uint32_t)0".
+  	Immediately after the terminating 0 follow the images, one by
+  	one, all aligned on "uint32_t" boundaries (size rounded up to
+  	a multiple of 4 bytes).
+  
+   "Firmware Images" are binary images containing firmware (like
+  	U-Boot or FPGA images) which usually will be programmed to
+  	flash memory.
+  
+   "Script files" are command sequences that will be executed by
+  	U-Boot's command interpreter; this feature is especially
+  	useful when you configure U-Boot to use a real shell (hush)
+  	as command interpreter.
