Yes! There have been a lot of updates in the PCIe MVEBU area. So it could have been a different reason why it did not work when you added support for this board. Still, without this board_late_init(), we would need to run "pci enum" and then "usb start" or "usb reset" to bring up the USB3 ports. The USB3 controller is on the PCIe bus, and MVEBU PCIe drivers don't initialize everything when it comes up. > > > - Remove unnecessary misc_init_r(), since NET_RANDOM_ETHADDR is now > > configured in > > So u-boot will assign random MAC addresses to the NICs instead of the > real ones? Won't this potentially break PXE boot setups? I did not see any problem using a random MAC address in my test using bootstd. Is there a setup where this board MAC address must be known when we boot with PXE? my impression is that only ipaddr and serverip are needed, and the MAC address could be whatever we define for the board. > > > - Remove unnecessary checkboard() > > - Updated IDENT_STRING to indicate this u-boot supports both Synology > > DS414 and DS214+ boards > > - Add SYS_THUMB_BUILD to reduce binary size > > - Add NET_RANDOM_ETHADDR > > - Add CONFIG_LBA48 and CONFIG_SYS_64BIT_LBA to support >2TB HDD/SDD > > > > Signed-off-by: Tony Dinh <mibo...@gmail.com> > > --- > > > > board/Synology/ds414/ds414.c | 15 +++-------- > > configs/ds414_defconfig | 20 ++++++-------- > > include/configs/ds414.h | 51 ++++++++++++++++++++++-------------- > > 3 files changed, 42 insertions(+), 44 deletions(-) > > > > diff --git a/board/Synology/ds414/ds414.c b/board/Synology/ds414/ds414.c > > index abe6f9eb5e..f0b55fa095 100644 > > --- a/board/Synology/ds414/ds414.c > > +++ b/board/Synology/ds414/ds414.c > > @@ -181,18 +181,9 @@ int board_init(void) > > return 0; > > } > > > > -int misc_init_r(void) > > +int board_late_init(void) > > { > > - if (!env_get("ethaddr")) { > > - puts("Incomplete environment, populating from SPI flash\n"); > > - do_syno_populate(0, NULL); > > - } > > - return 0; > > -} > > This is useful for first boot of flashed vanilla u-boot. Can this be > retained somehow? We could, but with NET_RANDOM_ETHADDR configured in, this routine will do nothing. Perhaps the fact that the envs will show CRC errors in the 1st boot should be an indicator that it needs to be populated? With standard boot enabled in this patch, the default envs can be scripted in /boot/boot.scr or /boot.scr on the rootfs disk storage, or on some flash location, or on the network . So we don't even need the full envs on SPI flash like we used to.

IIRC, > the usb*mode and eth*mtu settings are required, is that wrong? Lastly, MTU is default to 1500 in mvneta.c. So the eth*mtu env is no longer necessary. Also, I believe usb*mode is no longer necessary with the USB driver model. I have not come across their usage anywhere for a long time. The USB driver model seems to handle everything pretty well. > that update_uboot macro at least helps preventing people from writing > into wrong spots. What's the cause for dropping it? I think we usually use mtdparts to define where u-boot is. So users know where the right place to flash is. But you are right, it only helps to describe exactly how to flash a new u-boot. So I'll put that back in the V2 patch. Thanks for taking time to review the patch. And I'm glad to see you are still active with the u-boot community! All the best, Tony > > Thanks, Phil
