The first patch modifies the general imx53.dtsi file. The reason is to
make it possible to add Devicetree definition for the board (later in
this patch) as a copy from the Linux kernel -- such a DTS can be used
also to boot Linux kernel.
I am not sure if this should be in a separate patch or if this file
(imx53.dtsi) is being regularly mirrored from the Linux kernel.
The second patch modifies the IMX FEC driver to make it possible to
parse the gpio reset pin from the Devicetree and perform the reset in
the driver (thus saving unnecessary code duplication in different
board.c files). The added code is very similar to one in Linux kernel
driver.
The 3rd patch adds the Devicetree definition for the Voipac
x53-dmm-668 module (equipped with i.mx53 CPU) and Voipac Baseboard.
More info about the module might be found at:
http://www.voipac.com/#X53-DMM-668
The DTS files have already been accepted to Linux kernel (waiting in
linux-next). The rest is the necessary hardware initialization etc. The
devices successfully initialized (and tested) are uart0 and Ethernet.

I think, that there can be design where PHY reset is not controlled by MCU pin (it is usually possible even reset device through MDIO) and then it would be better to check if "phy-reset-gpios" is present and if not then skip whole attempt to manipulate GPIO. On the other hand if "phy-reset-gpios", it is required to configure it, because default pin state can/should lead to PHY reset. I.e. if (IS_ENABLED(CONFIG_OFDEVICE)) phy_reset = of_get_named_gpio(dev->device_node, "phy-reset-gpios", 0); if(phy_reset < 0) { print info ("\"phy-reset-gpios\" is not used for i.MX fec, skipping forced reset\n") } else { > > + if (!gpio_is_valid(phy_reset)) > > + goto err_free; > > + > > + ret = gpio_request(phy_reset, "phy-reset"); > > + if (ret) { > > + pr_err("Can not request gpio %d (phy-reset): %d\n", phy_reset, ret); > > + goto err_free; > > + } > > + > > + gpio_direction_output(phy_reset, 0); > > you need to check the return too > > > + udelay(10); > > + gpio_set_value(phy_reset, 1); } } > > + > > /* Reset chip. */ > > writel(FEC_ECNTRL_RESET, fec->regs + FEC_ECNTRL); > > while(readl(fec->regs + FEC_ECNTRL) & 1) { Best wishes, Pavel _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox ^ permalink raw reply [flat|nested] 13+ messages in thread

Thanks for spotting. The gpio pin should indeed be optional. The driver should only fail if the gpio is specified, but not working. It should not fail if there's no gpio specified at all.

I was investigating how the imx53-loco support is done, however I was not sure if the 'multiboard' is the preferred way. I found your patchset http://www.spinics.net/lists/u-boot-v2/msg15296.html shortly describing the functionality of the multiboard barebox -- I still do not understand the concept. The final binary has to hold just one particular 'flash_header', thus be able to boot just on one particular board. I do understand the flexibility of the devicetree, however something like the SDRAM configuration can not be chosen 'on the fly' by the PBL? It will save me (and probably others) a lot of time if you could quickly explain the functionality. I do agree the flash-header-imx53-loco.imxcfg looks much cleaner. I will try to write the flash_header for the Voipac board in the same way.

The multi image support (I think multi image is more appropriate than multi board) doesn't mean that the same image is being run on multiple boards, it instead means that the same binary is used to generate multiple images. Each of these images is for a particular board. The advantage over the traditional mechanism is that you can have a single config for multiple boards. Of course this could be used to have a single config for completely different SoCs/Boards. This gives you a better compile coverage with less compilation. A more real life scenario might be that you have two boards which differ only in the amount of SDRAM. Instead of maintaining two configs for it you could use a single config and generate two images from it. > I do > understand the flexibility of the devicetree, however something like the > SDRAM configuration can not be chosen 'on the fly' by the PBL? The basic trick with the multi image support is that we compile multiple entry points (ENTRY_FUNCTION()). Which one is used for a particular image is later specified with the -e option to ld. So each image has one entry function specified with ENTRY_FUNCTION(). What you then do in this entry function is up to you. If your boards offer some possibility to detect the SDRAM setup then you can use it to dynamically detect and configure SDRAM. Then you would be able to use a single binary image on multiple boards with different SDRAM configuration. On i.MX with the DCD header format the DCD is normally used to setup SDRAM. In this case it's not possible to have the same image for multiple boards. However, you could remove the SDRAM setup from DCD data and configure the flash header to load to the i.MX internal SRAM. then when in SRAM you could determine your board and setup the SDRAM from early code. This way a single image for multiple boards would be possible on i.MX aswell. With multi image support we shift away from "compiling for a single board". Instead a board is simply an additional option. If this option makes a new image necessary, then this image will be generated along with images for other boards. My vision is that we should not have defconfigs for particular boards. Instead we should have defconfigs which enable a certain feature set, for example: - arm_full_defconfig: All features and all boards enabled, huge binary nobody uses in projects, but is useful for compile testing and development - imx_defconfig: All i.MX boards enabled and all features necessary for i.MX. More practical in real life. - noninteractive_defconfig: Do not prompt users, just boot. - $VENDOR_defconfig: supports all boards from a vendor - $PROJECT_defconfig: supports all boards for a particular project which uses different boards or variants of boards. I hope this makes it a bit more clearer.
