It is *extremely* bad style to post the same information with slightly different text to different mailing lists.
My apologies: I recently moved from an email client to another one and I messed up... Of course, it's a bad style. Sorry.
Here is a copy of my reply to Claudio Scordino's posting on the linux-arm list:

So why don't you post it to the appropirate mailing list, i. e. u-boot-users? It's off topic here.
Note 1: the resulting binary cannot be distributed, as you have a license conflict with the Intel NPE code. You MUST NOT link U-Boot (under GPL) with this code.
Our idea is to release the patch *without* the Intel Microcode, so that the patch can be released under GPL license. Clearly, once you copy the Microcode (which is not GPL) and compile, the resulting binary is not GPL, due to Intel's license. But it wouldn't be in any case...
Note 2: your patch contains garbage; for example, it creates files like Makefile.orig, cpu/ixp/cpu.c.orig, cpu/ixp/interrupts.c.orig, cpu/ixp/serial.c.orig, cpu/ixp/timer.c.orig, drivers/pci_indirect.c.orig, cpu/ixp/config.mk.orig, ... which must not be included.
Also, pippo.txt is poroibably random garbage and should not be included.
As I said, we are experiencing a very busy period, and we didn't have enough time to properly clear the patch and submit it on the u-boot mailing list. We know that the patch is still very dirty. That's why we didn't ask to put it in the U-boot mainstream. But we wanted to release this alpha version on our website because someone may be interested. In the next weeks we'll provide a clean version of the patch.
Note 3: For CFI conformant flash chips you should use the CFI driver instead of a custom one.
If I'm not wrong, IXP425 uses a custom driver too. That's why we chose to go for a custom driver.
Note 4: Your patch violates the coding style (C++ comments, trailing white space, indentation not by TABs, etc.). Please cleanup.
We'll fix this. BTW, why indentation should not done by TABs ? In the Linux kernel code the use of TABs is mandatory...
Note 5: You patch adds debug code to common files (like common/cmd_bootm.c). You must never do this!
Note 6: Please doin;t add changelog style comments to files (like in cpu/ixp/start.S); we use git to track the history.
Note 7: Please don't modify white space in files which you don't touch at all (like drivers/cfi_flash.c).
Note 8: Be careful with hardware accesses; code like function get_reg() in drivers/ethixdp465.c is missing "volatile" attributes. Check all your code for this!
We'll fix all these issues.
So please clean up your code, fix the license issue, and (re-) submit your code on u-boot-users.
Ok. I don't know exactly when the final patch will be ready. In the meanwhile we put a new version (slightly better) on the same URL for those people that can't wait the final version.
Best regards,
Claudio Scordino
