Re: [U-Boot-Users] [PATCH 1/1] FAT Bare Partition Support
Hi JC, I have been busy on writing a Linux driver for the DSP on our AT572D940HF-EB board. Furthermore in the next 3 weeks I'm on vacation, please gimme more time cause I would like rework this patch but also support for our board and SDHC support for all Atmel devices together with Haarvard. Regards, Antonio R. 2008/8/2 Jean-Christophe PLAGNIOL-VILLARD [EMAIL PROTECTED] Telling the truth it seems that I've used this function during debug in fact at a deeper look it seems it disappeared from the code a part the definition. Ok I'm going to fix the problem and re-submit. Any update about the re-submit patch?

Need to build nios2
I've prefer to move conditional compilation to Makefile instead of
you move an include in xuartlite. Which is not related to nios2.

You *would* have to know that the first element of the path is an /aliases dereference. Your original patch did not require that piece of knowledge (but silently and automagically, which makes me nervous). did we come to resolution on this? I'd like to see this in 1.3.5. - k Hi Kumar, I think we have basic resolution - I would like to see it in 1.3.5 too. I haven't pushed on this, waiting for 1.3.5 window to open (or some free time, whichever comes last). I've CC:ed David Gibson in case he has some advice - the concept is to indicate a dereference of /aliases nodes so that us lazy engineers don't have to cut'n'paste the whole long path from the alias. Kumar originally proposed to do it automagically and I countered proposing using * to indicate the next path name should be looked up in /aliases and the result used instead (i.e. dereferenced). Discussion thread: http://thread.gmane.org/gmane.comp.boot-loaders.u-boot/43575/focus=44941 Looking at the ieee1275 doc http://playground.sun.com/pub/1275/coredoc/1275-1994/1275.ps.gz it looks like * will work for a dereference delimiter as it is not listed as one of the permitted punctuation characters in a node name. Quoting 3.2.1.1 Node names: -- The driver name field is a sequence of between one and 31 letters, digits, and punctuation characters from the set , . _ + - . Uppercase and lowercase characters are distinct. -- We do have a problem with property names, where * _is_ a legal name component. Quoting 3.2.2.1.1 Property names: -- The property name is a human-readable text string consisting of one to thirty-one printable characters. Property names shall not contain uppercase characters or the characters /, \, :, [, ] and @. -- Note that * is not proscribed, making it a legal character in a property name. Having noted that, I'm willing to take the risk and use * for the alias dereference separator. Looking back at the original patch, Kumar's original patch only did the /aliases dereference for the fdt print command. I'm thinking more general purpose: being able to dereference /aliases in all fdt commands. This seems helpful for the fdt set command, for instance. Whether this is reasonable to implement remains to be seen...

I was wondering if anyone has actually looked at doing this. What about creating a tool that parses a device tree and creates (or updates) the board header file? This will retain compatibility with other platforms, clean up the existing header files (they won't need to contain as much information), and reduce the amount of changes to U-Boot itself. That's a good idea. I have used variation on this concept in the past and they have worked out well. A perfect tool would take a fully populated DTS file and use it to dynamically generate all of the needed header files to build uboot. More info would need to be added to the DTS file like DRAM timings, etc. But a DTS file is good place to track all of that info. The generated uboot image could contain a copy of the DTB and feed it to Linux.

Re: [U-Boot-Users] Power.org open-firmware/device trees ePAPR reference
David Hawkins wrote: Hi, I just received an email from Power.org referencing this document: http://www.power.org/resources/downloads/Power_ePAPR_APPROVED_v1.0.pdf The ePAPR is loosely related to the IEEE 1275 Open Firmware standard—IEEE Standard for Boot (Initialization Configuration) Firmware: Core Requirements and Practices. It looks to have a nice description of device trees. I see lots of familiar U-Boot developer names in the acknowledgments, so I imagine U-Boot is probably compliant with this specification already. Looks like a useful document to reference somewhere on the Denx documentation area. Cheers, Dave Hi Dave, Thanks for the pointer. I have a collection of useful IEEE-1275 / FDT pointers on my custodian page and added your reference to the collection: http://www.denx.de/wiki/view/U-Boot/UBootFdtInfo#Background_Information_on_Flatte Some of these references may deserve a higher visibility location.
