This is a problem that will turn up in the future even more, so I propose to solve it correctly now. It will not be long before we want to have our own configuration for our MCV module and this will certainly be sold by DENX. I think we need an infrastructure to allow for boards sold by arbitrary manufacturers all using the Altera chip. The situation as such is not uncommon, so maybe you can follow examples from different CPUs? I.e. how is the imx6 handled on the different base boards? Cheers Detlev

AFAICT, one solution would be to put "-" in that column, and do "git mv board/altera/ board/socfpga/". But if we decide to go that way, it should really be separate patch. Best regards, Pavel

Putting "-" in the vendor column just doesn't feel right. How about using a minimal board C file for socrates under ebv/socrates that only implements checkboard and shares the rest? > But if we decide to go that way, it should really be separate patch. I still like to see a solution that scales to things we already know will happen ;) Looking at the original patch, with this in mind even the #define ALTERA_BOARD_NAME doesn't look right any longer. Thanks Detlev

(Too much changes for too little gain.) Actually.. there's nothing Altera specific in board/altera (it works on ebv just fine), so board/socfpga sounds like a better name. But I don't think such rename should be done lightly, so I still believe the patch as submitted is the best way to go. > > But if we decide to go that way, it should really be separate patch. > > I still like to see a solution that scales to things we already know > will happen ;) Looking at the original patch, with this in mind even > the #define ALTERA_BOARD_NAME doesn't look right any longer. I don't know what will happen next. Albert asked me to resubmit patch updated to newer code, which I did. Best regards, Pavel

I think Detlev is right here. We do have specific board vendors directories, and there are a number of reasons to keep this used (just to give one example: say a vendor wants to use a similar look and feel for the default environment settings etc. for all boards). If there is code which is identical for several (or all?) boards we should ask ourself if it really belongs into the board/ directory at all? > Actually.. there's nothing Altera specific in board/altera (it works > on ebv just fine), so board/socfpga sounds like a better name. But I > don't think such rename should be done lightly, so I still believe the > patch as submitted is the best way to go. I think board/altera as such makes sense, with Altera being the vendor of that specific board. However, if there is common code there, this code should be moved out of board/ . [Note that I'm just commenting from an outside point of view; I did not check to what extent the "common" code under discussion here is truely common to all possible board configs.] Best regards, Wolfgang Denk

That might be the case. It seems that current code in board/altera is SoC-specific, as it works on both Altera and EBV boards. > > Actually.. there's nothing Altera specific in board/altera (it works > > on ebv just fine), so board/socfpga sounds like a better name.

However, if there is common code there, this > code should be moved out of board/ . It seems there's currently 99.99% of SoC-specific code there. What would be the right place for that code? arch/arm/cpu/armv7/socfpga/ ? But it is not really armv7-specific. drivers/misc ? Do we need to make a soc/ directory? And then... who does the move? It is not going to make merging between rocketboards.org and mainline even trickier than it already is :-(. Best regards, Pavel

Depends on what exactly it implements. Apart from that we can also take a look at where the code is in a Linux tree and take that as an example. After all, we want people developing the Linux kernel to also feel at home in the U-Boot sources. > arch/arm/cpu/armv7/socfpga/ ? But it is not really armv7-specific. > drivers/misc ? Do we need to make a soc/ directory? We have arch/arm/imx-common for example, but I'm not so sure if this is a good approach. Maybe there is not a _single_ correct place, but we have to distribute the files to multiple directories? > And then... who does the move?

Usually we care only to a certain degree for non-mainline code, though. Blocking ourselves because of non-mainline code would allow "external" control which I think is not really helpful for the project. Cheers Detlev

Yup, some other board vendors are using different HW configuration. Some of the difference are Altera dev kit have EEPROM and using Micrel PHY for EMAC. I presume Socrates board should have their own board path such as board/socrates/socfpga. > > >> > > > AFAICT, one solution would be to put "-" in that column, and > >> > > > do "git > >> > > > mv board/altera/ board/socfpga/". > >> > > > >> > > Putting "-" in the vendor column just doesn't feel right. > >> > > >> > That's what mx6 did, AFAICT. > >> > >> I think Detlev is right here.

HW configuration handoff files (such as pinmux_config, pll_config). Pinmux might be different as certain board might have different routing (normally to optimize the board layout and shorter PCB trace length). 2. Board specific code (socfpga_cyclone5.c) These functions include board_init, board_early_init, checkboard. I believe that the function print_cpuinfo and overwrite _console should goto arch/arm/cpu/armv7/socfpga/misc.c. I will create the patch to change this later (as I already did this at rocketboard.org). > > >> > Actually.. there's nothing Altera specific in board/altera (it works > >> > on ebv just fine), so board/socfpga sounds like a better name.

Altera Cyclone 5 board is very different board (big, rectangular, expensive) than EBV Socrates (small, circular, cheap) board. Different parts are used there, too, but same configuration of u-boot works on both. Nevertheless, printing wrong name confuses users. Virtual target is completely different, and board configured for it will not boot on physical targets. Therefore this splits the configuration so that u-boot knows they are different. So far it is only used for correcting the puts, but there may be other uses in future. Signed-off-by: Pavel Machek <pavel@denx.de> --- Diff from v1: separate virtual target, too, and make it apply to recent u-boot.
