Fix linker scripts: add NOLOAD atribute to .bss/.sbss sections

2008-01-12T19:31:39+00:00

With recent toolchain versions, some boards would not build because
or errors like this one (here for ocotea board when building with
ELDK 4.2 beta):
ppc_4xx-ld: section .bootpg [fffff000 -> fffff23b] overlaps section .bss [fffee900 -> fffff8ab]

For many boards, the .bss section is big enough that it wraps around
at the end of the address space (0xFFFFFFFF), so the problem will not
be visible unless you use a 64 bit tool chain for development. On
some boards however, changes to the code size (due to different
optimizations) we bail out with section overlaps like above.

The fix is to add the NOLOAD attribute to the .bss and .sbss
sections, telling the linker that .bss does not consume any space in
the image.

2003-10-15T23:53:47+00:00

  - Added Motorola CPU 8540/8560 support (cpu/85xx)
  - Added Motorola MPC8540ADS board support (board/mpc8540ads)
  - Added Motorola MPC8560ADS board support (board/mpc8560ads)

* Minor code cleanup

* Patch by Scott McNutt, 04 Oct 2003:

2003-10-08T23:26:14+00:00

  - add support for Altera Nios-32 CPU
  - add support for Nios Cyclone Development Kit (DK-1C20)

* Patch by Steven Scholz, 29 Sep 2003:
  - A second parameter for bootm overwrites the load address for
    "Standalone Application" images.
  - bootm sets environment variable "filesize" to the resulting
    (uncompressed) data length for "Standalone Application" images
    when autostart is set to "no". Now you can do something like
       if bootm $fpgadata $some_free_ram ; then
               fpga load 0 $some_free_ram $filesize
       fi
