NULL is an absolute value and should not be relocated.
After this correction code like:
 void weak_fun(void) __attribute__((weak));
 printf("weak_fun:%p\n", weak_fun);
will still print null after relocation.

- adapt to the more generic EXCEPTION_PROLOG and CRIT_EXCEPTION macros
- minor 4xx cleanup

- Add low-boot option for MPC8260ADS board (if lowboot is selected,
  the jumper for the HRCW source should select flash. If lowboot is
  not selected, the jumper for the HRCW source should select the
  BCSR.
- change default load base address to 0x00400000

  applications: instead of using (PPC-specific) system calls we now
  use a jump table; please see doc/README.standalone for details

* Patch by Dave Westwood, 24 Jul 2003:
  added support for Unity OS (a proprietary OS)

  - remove trailing white space, trailing empty lines, C++ comments, etc.
  - split cmd_boot.c (separate cmd_bdinfo.c and cmd_load.c)

* Patches by Kenneth Johansson, 25 Jun 2003:
  - major rework of command structure
    (work done mostly by Michal Cendrowski and Joakim Kristiansen)

  - rewrite of the S3C24X0 register definitions stuff
  - "driver" for the built-in S3C24X0 RTC

* Patches by Yuli Barcohen, 12 Jun 2003:
  - Add MII support and Ethernet PHY initialization for MPC8260ADS board
  - Fix incorrect SIUMCR initialisation caused by wrong Hard Reset
    configuration word supplied by FPGA on some MPC8260ADS boards

* Patch by Pantelis Antoniou, 10 Jun 2003:
  Unify status LED interface

  - Added support for custom keyboards, initialized by defining a
    board-specific drv_keyboard_init as well as defining CONFIG_KEYBOARD .
  - Added support for the RBC823 board.
  - cpu/mpc8xx/lcd.c now automatically calculates the
    Horizontal Pixel Count field.

* Fix alignment problem in BOOTP (dhcp_leasetime option)
  [pointed out by Nicolas Lacressonnire, 2 Jun 2003]

* Patch by Mark Rakes, 14 May 2003:
  add support for Intel e1000 gig cards.

* Patch by Nye Liu, 3 Jun 2003:
  fix critical typo in MAMR definition (include/mpc8xx.h)

* Fix requirement to align U-Boot image on 16 kB boundaries on PPC.

* Patch by Klaus Heydeck, 2 Jun 2003
  Minor changes for KUP4K configuration

  instead CFG_MONITOR_LEN is now only used to determine  _at_compile_
  _time_  (!) if the environment is embedded within the U-Boot image,
  or in a separate flash sector.

* Cleanup CFG_DER #defines in config files (wd maintained only)

  Fix problem with only partially cleared .bss segment

* Patch by Rune Torgersen, 12 May 2003:
  get PCI to work on a MPC8266ADS board; incorporate change to
  cpu/mpc8260/pci.c to enable overrides of PCI memory parameters

  Fix misc problems with AmigaOne support

* Patch by Chris Hallinan, 3 Dec 2002:
  minor cleanup to the MPC8245 EPIC driver

* Patch by David Mller, 27 Nov 2002:
  fix output of "pciinfo" command for CardBus bridge devices.

* Fix bug in TQM8260 board detection - boards got stuck when board ID
  was not readable
