We don't know your hardware, we don;t know your kenrel port to your hardware, we don't know your custom PCIe device, we don't know your driver for it, we don't know your changes to the device tree to describe this hardware, we don;t see your kernel's log messages, we don't see your system's output of the "lspci" command with suitable options - we don't know nothing. How do you expect us to help without any of the relevant information? Also, your question has nothing to do with the ELDK, so you are off(Continue reading)

[PATCH][RFSB] Expand mkfs.jffs2 options
Hi Ron, > This patch will add the options for page size, image padding, clean markers, > and clean marker size.

It is not normally > + appropriate to specify a size other than the default 12 bytes. I never used that option so I'm unsure about this. Do we ever want to change this value? I really would like to only offer options that are sensible to change. If it is sensible to have this option, then from what I read in the documentation, 12 is indeed a good default as it does not seem to depend on the actual device. Am I right? If we agree on how to proceed, I can fix up the patch myself. Thanks(Continue reading)

Leaving it out all together and assuming the default would probably be best.(Continue reading)

Unkomprimiertes uImage für PPC
Zwei Fragen: 1) Gibt es auf der DENX-Seite ein Archiv dieser Mailingliste? Ich habe innerhalb meines pers?nlichen Timeouts von 5 Minuten keines gefunden. 2) wie kann ich dem Linux-Kernel sagen, dass er mein uImage nicht komprimieren soll (TQM5200, PPC, U-BOOT)? Danke und Gr??e, Marc Scherer

XIP und Suche im Mailarchiv
Hallo, 1) Ich versuche gerade, die Boot-Zeit eines TQM5200 zu optimieren. Im aktuellen Kernel (aus dem Denx-Git-Repository) scheint es allerdings keine Unterst?tzung f?r XIP beim MPC5200 zu geben. Stimmt das? 2) Es w?re sehr sch?n (komfortabel), wenn man im Mailinglisten-Archiv nach einem Stichwort suchen k?nnte oder wenn wenigstens das gesamte Archiv (alle Monate) als eine Seite oder eine Datei zur Verf?gung st?nde. Ich mach's jetzt mit wget und cat, aber das m?sste ja nicht sein.

There is no XIP support in recent versions for Power Architecture. Also, from what I have seen so far, XIP will usually not save any time (often it makes the systems slower instead). It will save RAM, that's all. > 2) Es w?re sehr sch?n (komfortabel), wenn man im Mailinglisten-Archiv > nach einem Stichwort suchen k?nnte oder wenn wenigstens das gesamte > Archiv (alle Monate) als eine Seite oder eine Datei zur Verf?gung > st?nde.
