[U-Boot] Issues with memory mapping for AT91SAM9G25-EK
by Vasi Vilvoiu 18 Oct '16

18 Oct '16

Hello, I'm trying to use AT91SAM9G25-EK board for machine learning. One of the reasons I chose this board, besides it targeting ARM9 which was my focus, is that is has 1GB of RAM. I've used the following guide to setup a Debian installation: https://eewiki.net/display/linuxonarm/AT91SAM9x5 The gist of it is, I'm using AT91Bootstrap as a first stage bootloader and u-boot as a second stage. I'm compiling from github (branch v2016.07-rc2) and patching it with the following: https://rcn-ee.com/repos/git/u-boot-patches/v2016.07-rc2/0001-at91sam9x5ek-… Everything works well, but linux cannot see more than 128MB of the memory. I'm (almost) a complete noob when it comes to embedded programming, but what I understood so far is that u-boot defines the memory layout in the configuration files. Sure enough, I found the definitions that limit the memory being used: https://github.com/u-boot/u-boot/blob/master/include/configs/at91sam9x5ek.h Could I please get some help adjusting it in order to use all available memory? I tried changing CONFIG_SYS_SDRAM_SIZE to 512MB (0x20000000) and it won't boot. Also changing "fdtaddr" (which I have no idea what it does) in CONFIG_EXTRA_ENV_SETTINGS to "fdtaddr=0x39FF0000" yields the same result. For the moment I lack a RS232 port on my dev machine, so I can't give you more insight into what fails. But I'm obviously doing something horribly wrong here, so if you could give me some tips or point me to some relevant documentation, I would be grateful. Thank you!

[U-Boot] [PATCH] efi_loader: Revert device_handle to disk after net boot
by Alexander Graf 18 Oct '16

18 Oct '16

When you boot an efi payload from network, then exit that payload and load another payload from disk afterwords, the disk payload will currently see the network device as its boot path. This breaks grub2 for example which tries to find its modules based on the path it was loaded from. This patch fixes that issue by always reverting to disk paths if we're not in the network boot. That way the data structures after a network boot look the same as before.

[U-Boot] Blackfin serial driver

Hi Sonic, Do you have plans to convert the Blackfin serial driver to driver model? I don't have a board myself, but it looks like there is fairly recent activity with this arch in U-Boot. Regards, Simon

[U-Boot] *preferred* place in u-boot to tweak device tree?
by Robert P. J. Day 18 Oct '16

18 Oct '16

a while back, i asked about the best way to have u-boot extract the MAC address from a well-known address in flash, and add it to the device tree to pass to the kernel; discussion was here: http://lists.denx.de/pipermail/u-boot/2016-May/255856.html i notice that another option for tweaking the MAC address that is popular is to add that code to a board's misc_init_r(). so both ways work just fine, but i'm assuming that the *proper* place to do it is in ft_board_setup(), since the routine image_setup_libfdt() pretty much handles everything, and all that's left to do is extend ft_board_setup() to set the env variable: eth_setenv_enetaddr("ethaddr", <physical addr of 6-byte MAC address>); is that what you'd call "best practice"? rday -- ======================================================================== Robert P.

[U-Boot] [PATCH] pinctrl: uniphier: fix unused-const-variable warnings for GCC 6.x
by Masahiro Yamada 18 Oct '16

18 Oct '16

Marek reports warnings in UniPhier pinctrl drivers when compiled by GCC 6.x, like: drivers/pinctrl/uniphier/pinctrl-uniphier-ld20.c:58:18: warning: 'usb3_muxvals' defined but not used [-Wunused-const-variable=] static const int usb3_muxvals[] = {0, 0}; ^~~~~~~~~~~~ My intention here is to compile minimum set of pin data for SPL to save memory footprint, but GCC these days is clever enough to notice unused data arrays. We can fix it by sprinkling around __maybe_unused on those arrays, but I did not do that because they are counterparts of the pinctrl drivers in Linux. All the pin data were just copy-pasted from Linux and are kept in sync for maintainability. I chose a bit tricky way to fix the issue; calculate ARRAY_SIZE of *_pins and *_muxvals and set their sum to an unused struct member. This trick will satisfy GCC because the data arrays are used anyway, but such data arrays will be dropped from the final binary because the pointers to them are not used.
