I finally had the time (and board) to spend some time with
crosstool-NG version 1.5.2 and TMS320DM6446 (DaVinci Digital Media
System-on-Chip,
http://focus.ti.com/docs/prod/folders/print/tms320dm6446.html).

I was able to successfully build and run v2.6.27-davinci1 kernel
(Kevin Hilman's branch) with busybox based initramfs on it. I don't
believe that any later kernel would represent any challenge (it just
happens that I'm currently working with this version). What a thrill
:).

crosstool-NG/toolchain config is attached. It may be useful to someone
using crosstool-NG ...

 #!@@CT_bash@@

 # What we need:

 #  - the .config file

 # Parse the tools' paths configuration

 . "${CT_LIB_DIR}/paths.mk"

 # We'll need the stdout later, save it

 exec 7>&1

 # Parse the common functions

 . "${CT_LIB_DIR}/scripts/functions"

 # Don't care about any log file

 exec >/dev/null

 rm -f "${tmp_log_file}"

 # Parse the configuration file

 . .config

 # Parse architecture and kernel specific functions

 . "${CT_LIB_DIR}/scripts/build/arch/${CT_ARCH}.sh"

 . "${CT_LIB_DIR}/scripts/build/kernel/${CT_KERNEL}.sh"

 # Build CT_TARGET

 CT_DoBuildTargetTuple

 # All this for this single echo... :-( Sigh, I'll have to re-arrange things...

 echo "${CT_TARGET}" >&7
