Venerable cramfs fs Linear XIP patch originally from MontaVista, used in
the embedded Linux community for years, updated for 2.6.21. Tested on
several systems with NOR Flash. PXA270, TI OMAP2430, ARM Versatile and
Freescale iMX31ADS.


When trying to verify this patch on our PXA270 system we get the
following error when running an XIP rootfs:

cramfs: checking physical address 0xa00000 for linear cramfs image
cramfs: linear cramfs image appears to be 3236 KB in size
VFS: Mounted root (cramfs filesystem) readonly.
Freeing init memory: 96K
/sbin/init: error while loading shared libraries: libgcc_s.so.1:
failed to map segment from shared object: Error 11
Kernel panic - not syncing: Attempted to kill init!

However, if our busybox binary is XIP while the libgcc_s.so.1 is not
XIP, busybox runs fine.

Richard, May I email you the rootfs tarball so you can recreate what
we are seeing?  It is a little less than 2MiB.  The filing system
executables will only run on a PXA27x processor.
