[U-Boot] CONFIG_SYS_SDRAM_BASE error
Hi, I try compiling u-boot for Iomega iConnect using these files: http://patchwork.openwrt.org/patch/299/ But I got this error: board.c: In function â__dram_init_banksizeâ: board.c:233: error: âCONFIG_SYS_SDRAM_BASEâ undeclared (first use in this function) board.c:233: error: (Each undeclared identifier is reported only once board.c:233: error: for each function it appears in.) board.c: In function âboard_init_fâ: board.c:279: error: âCONFIG_SYS_INIT_SP_ADDRâ undeclared (first use in this function) board.c:312: error: âCONFIG_SYS_SDRAM_BASEâ undeclared (first use in this function) make[1]: *** [board.o] Error 1 I found this thread, it seems to be a solution, but I don't know how to do: http://www.mail-archive.com/u-boot@lists.denx.de/msg36109.html Please could you help me?

[U-Boot] [PATCH] 85XX: Fix pin muxing for second USB controller
On P1022/P1013 second USB controller is muxed with second
Ethernet controller. The current code to enable second USB
fails to properly clear pinmux bits used by ethernet. As a
result, Linux freezes when this controller is used. This
patch fixes the problem.

You can find all the implementation in: arch/arm/cpu/armv7/omap3/gpio.c and the header is: arch/arm/include/asm/arch-omap3/gpio.h All you need is to include the header, request the appropriate gpio, send the pulse and maybe (if you don't need it anymore) free that gpio.

Re: [U-Boot] SPL framework re-design
Hi, You mentioned that /spl can not be used for source files. Isn't there a way to workaround this problem? Why should we have source files in a SPL directory? I would prefer to have spl specific sources right where the rest ist - maybe marked with something like _spl or excluded by some #define-test. If we have a SPL specific directory we have to copy most of the tree (arch/cpu etc.) which in my eyes is totally unnecessary if we don't do the symlinking stuff... Also, I agree with Scott's opinion that re-compiling some files while re-using the binary of some other files won't be a good idea. In this case, CONFIG_PRELOADER will be honored in some files but not in other files. That will be a source of confusion for developers. I also see this as the biggest problem with reusing the object-files. It will add more complexity than a simple re-run with different flags like suggested by Daniel. BTW, John Rigby had sent out a series sometime back for OMAP3 NAND SPL. That can be integrated with my work and we will get an SPL that supports both MMC and NAND. I guess Simon Schwarz is also doing some work lately on OMAP3. I am working on OMAP3 (on devkit8000). If this discussion comes to a conclusion soon I would prefer sending the patches with the new SPL format.

I can't seem to find a mail from Mike on this thread. Did I miss any mail? I can find it either. I don't know what I had in mind then. Do you mean re-using equivalent libraries from the normal U-Boot without re-compiling them? There are actually two different topics here: - The first is how to link all the objects in the spl/ tree together. As I understand, you proposal was to link all objects in each of the subdirectories into a library, and then link all the libraries together. Instead of doing this, we could as well just maintain a list of objects and then link all these together directly, without creating libraries first. - The other topic is if to build new object files, and where. At the moment we have two situations: * Some files are built with special options such that unneeded code gets commented out using respecive #ifdef's / #ifndef's. We can probably get rid of (most of ?) these #ifdef's / #ifndef's when properly using -ffunction-sections / --gc-sections Why should we then recompile the code? * Some files (start.S) really need different code. Here the questions is more how and where to recompile using proper options. I would be glad if we could get rid of the symlinking. Maybe we can add respective build rules to the original Makefiles (see also proposal by Ilya, http://article.gmane.org/gmane.comp.boot-loaders.u-boot/102033 ), eventually just using a different suffix, say .splo instead of .o? allow for vendor directories (where BOARDDIR = $(VENDOR)/$(BOARD)). I didn't want to make the directory structure any longer than required. But I can add this if required. It will be needed. Hm... can we try to do without the symlinks? Well. I think it's difficult. Most of my hardware initialization such as clock init, SDRAM init etc need to know under what context it is getting executed. The context can be: 1. SPL 2. Regular U-Boot executing from NOR flash 3. Regular U-Boot executing from SDRAM etc. Agreed - we need another, independent set of object files. But cannot we create these in the existent source tree? If you want to do away with symlinks, I would propose going with Daniel's approach. This uses /spl as a remote building directory, but do not create any symlinks. Yes, this is an improvement over the current situation - but Ilya's question is a good one: why do we need the pl/ subtree in the first place?

It is already there, you just need to use it instead of writing directly to the GPIO registers.

Dear Scott Wood, In message 20110627134205.021af...@schlenkerla.am.freescale.net you wrote: This statement does not make much sense to me. If we can do it in the spl/ directory, we should be able to do it in any other directory as well. The worst to happen is that we have to keep two setsof object files separated, but chosing a different suffix should be sufficient. We do it in the spl/ directory by bypassing the normal makefile config system, specifying a board-and-spl-specific list of objects instead. We can provide such a board-and-spl-specific list of objects for the spl code in the normal Makefiles as well. It could of course be done with the standard config system, but it will require that every bit of code in U-Boot be enabled only with a particular config option -- no always on code. This would be a good thing anyway, but it will take some work to do it cleanly. A first step would probably be a global finegrained/small flag that configs use to opt into the new system, but eventually all bits of functionality should have appropriate individual config symbols. If we do it right, we will only build such objects in spl configuration that are needed for the spl linking. So we can start with this finer control for spl initially, and then (later) extend it for normal builds as well.

Re: [U-Boot] SPL framework re-design
Hi All, Just thought I'd throw in a left-field idea... Could we make the loading of U-Boot into a generic multi-stage framework with each stage bootstrapping the next stage? OK, I know this is how IPL, SPL etc work already, but I'm thinking something more formal and arch independent. I can think of three disctinct phases which are relatively commong across most arch's (especially NAND Flash arches) 1) An intial page (say 256 bytes for example) which loads a second stage into the CPU's cache 2) A second phase running in the CPU cache which initialises SDRAM and loads the remainder into main memory (performs relocations etc) 3) A final phase which is U-Boot proper, running at the final target address in SDRAM Now what I'm thinking is that if we formalise these loader stages, we could actually add a little more flexibility by, say, allowing the final U-Boot binary to reside on a file-system. And even break the final binary up into smaller 'run-once-and-discard' chunks. For example, a lot of the low level init is only ever done once, but it stays in SDRAM as a permanent piece of the U-Boot image - What if the second stage loader could instead load an low-level init blob and run it before loading the final U-Boot blob? This then opens the door for all sort of options - What if U-Boot commands were build into stand-alone binary blobs and only loaded when needed. Same with device drivers So a lot of what is now build-time configuration could be reduced to run-time configuration Just a few wild ideas...

Depending on your architecture, the initialization of the RAM may be semi-automatic (with just very few parameters needed), or data-driven (you have to provide some magic data blob that gets interpreted by some ROM code), or completely manual (where you have to pay close attentian to insert the correct N microseconds delay here and there in your code, as required by the RAM data sheet). If you look back at the trouble reports from people who ported U-Boot (and Linux) to their platforms you can see that RAM initialization problems have always been a major problem area. This experience, collected over many years, has led to the design we have now: http://www.denx.de/wiki/view/U-Boot/DesignPrinciples#6_Keep_it_Debuggable Having debug output on the console as soon as possible is a pretty important design goal; if technically possible, we do want to have debug output long before initializing the RAM. Unfortunately, this pulls in a lot of dependencies: bigger parts of the code like printf() and friends, access to the environment (to read the baudrate settings, etc.) Now what I'm thinking is that if we formalise these loader stages, we could actually add a little more flexibility by, say, allowing the final U-Boot binary to reside on a file-system. And even break the final binary up into smaller 'run-once-and-discard' chunks.

You would most probably lose the capability to have early debug messages. This then opens the door for all sort of options - What if U-Boot commands were build into stand-alone binary blobs and only loaded when needed. Same with device drivers Device drivers clearly need a rework. But I'm not sure if dynamic loading is as easy as you imagine it - we have a large number of architectures here, and you need some support (drivers, file system [or other structured storage space]) to koads objects from external storage. So a lot of what is now build-time configuration could be reduced to run-time configuration It sounds like a nice idea, but I fear there are a lots of devils in the details.
