Hi Denis, thanks for your patch. In general I think it could be a good idea to support distroboot on this board, especially if we can maintain compatibility with the existing boot procedure. However, since this board repeatedly has size problems with the u-boot binary, we carefully need to check binary size. More questions inline.

Per the README (I had to double check), if SYS_BOOTMAPSZ is not set then if bootm_size is set in the environment we use that. So in the end, same thing. And we just drop initrd_high here.

I also experienced size issues with the stock tbs2910_defconfig, and for now I just locally removed support for things that eats up too much space like PCIe support. > There in no SPL for tbs2910. So this is not required. Ahh ok, now I understand. That probably explains the repeated size issues. For my patch, I could guard the code addition with some ifdefs for CONFIG_DISTRO_DEFAULTS if necessary. Note that CONFIG_DISTRO_DEFAULTS is not set in the tbs2910_defconfig, so if done correctly it should not make things worse. In the long run it's probably worth looking into adding SPL support. For instance the Wandboard has it. I'll try to find the time to look into it but I can't guarantee anything.

I'm a bit confused with it: There seem to be many way to do the same thing and I'm not sure which one is the best. Because of that, I just kept it in the code as it was (instead of moving it to tbs2910_defconfig). I'm also not sure if it's best to run distro_bootcmd before or after the bootcmd_up1/bootcmd_up2/bootcmd_mmc commands, which are probably used to boot some distribution like LibreElec.

With SPL+u-boot proper it would be even worse, since then there is a gap between SPL and u-boot, u-boot starts at higher address in eMMC, and it would not be smaller. And this 2-stage boot would break the documented u-boot update procedure, since we have to flash 2 files then. > > For my patch, I could guard the code addition with some ifdefs for > CONFIG_DISTRO_DEFAULTS if necessary.

That means, without this change in defconfig the whole distroboot does not work?

Otherwise you would break compatibility to the existing boot flow. One additional comment: currently we want to strip down the embedded dtb to reduce size. This means we cannot pass this dtb to linux, and always need to load a different one (together with kernel and initrd). This is no problem for extlinux.conf, but maybe we can omit to define fdtfile just to make sure we have to load a different one. I'm not sure, however, if distroboot scripts work without this default dtb. Soeren

Once loaded, the SPL would initialize the RAM, detect the boot media, and fetch u-boot.img from it, and execute it. I also hoped the the SPL would have been significantly smaller than the current u-boot.imx image. In the meantime, I'll send a v2 with some additional patches to reduce the size of the resulting u-boot.imx. Denis. -------------- next part -------------- A non-text attachment was scrubbed...

This initializes the DDR controller first, then loads the executable payload, u-boot.bin in this case. So there is no restriction from SRAM size, as long as the DDR settings are fixed, what is the case for tbs2910. > > I also hoped the the SPL would have been significantly smaller than the > current u-boot.imx image.

If CONFIG_BOOTCOMMAND is not defined before, it will be defined in config_distro_bootcmd.h This means that the order in which defines and #include <config_distro_bootcmd.h> is done matters. Which lead me to do the inclusion of config_distro_bootcmd.h as early as possible in the tbs2910.h. This way if there are some unintended redefinition due to things having changed in config_distro_bootcmd.h in the future, the compiler will at warn or error about it.
