Dear Jamie,

That's too bad. I've been developing for the board for the past 3 years
and
only recently have been given the opportunity to re-examine the loader
and root
file system.
It would be trivial to re-add the board if there is someone who actively maintains the related code.
I reverted 'v2011.06-0-gb1af6f5' without knowing the support had been taken away (I saw "m501sk" in boards.cfg.) It was only after I made some changes that I found this thread.
If I'm successful, I can post changes, and could take on support, but if you're not getting any pull for M501 cards is it worth it?

All these modifications are bogus and should be removed. They are not needed either.
Is the configuration meant to create a symbolic link (asm/arch -> asm/arch-at91)? If so I'll have to investigate how the make works. Without the above changes I get the error:
/u-boot/include/asm/arch-at91/hardware.h:28:34: error: asm/arch/at91rm9200.h: No such file or directory
It seemed harmless enough to change the "hardware.h" file as it itself is located in the "arch-at91" directory.

This is a highly cryptic way to say "+ 8192" - is there any rationale for such an unreadable way to express this?
Okay ... fair enough.

Hm - after reverting commit b1a2bd4 and then applying your patches, I still get:
Configuring for m501sk board... make[1]: *** No targets specified and no makefile found. Stop. make: *** [arch/arm/cpu/arm920t/at91rm9200/libat91rm9200.o] Error 2
Sorry, this does not work.
I get the error when I revert to b1a2bd4 too, but the patch above I applied the to b1af6f5.
The commands I did in order were:
~/$ git clone git://git.denx.de/u-boot.git && cd u-boot ~/$ git checkout b1af6f5 ~/$ patch -p1 < ../my-m501sk.patch ~/$ make m501sk_config ~/$ make all
I'm not at a computer with a working linker, but the build goes through until the final "arm-...-ld" linker line.
