Facilities for successful boot detection
by Mauro Condarelli 02 Jan '20

02 Jan '20

I would like to implement an update system (most likely using SWUpdate) "Double copy with fall-back" and, possibly a "last resort" recovery. I have pretty clear what should be the program flow, but I don't know how to implement it in U-Boot. In particular: * How can I determine, in U-Boot, if previous boot was successful? * Is there a established "best practice" for this? * I would like to avoid rewriting Environment at each reboot (it can happen /many/ times/day and that would kill SPI NOR). * In U-Boot there's a BootCounter, but Ive been unable to understand if/how it works and I strongly doubt it will be useful because it stores the counter itself in a uController register that is cleared on hard reset (and, of course, at power-up). Since my only way to "recover" from a failed boot may well be power-cycle I suspect this method is scarcely usable (but I might have missed something). * OTOH, as said, rewriting Environment (currently in SPI NOR) at each boot doesn't seem advisable. What I am aiming at (but I'm ready to change, if there's a better way) is: * my board (VoCore2 SoM) has: o 128MiB RAM o 16MiB SPI NOR (MTD) o 8GiB SD card (MMC) * On SD I should have: o One FAT-formatted partition containing two kernel images. o Two ext4 partitions containing RootFS (one for each kernel image). o Two ext4 partitions for Application (to be mounted on /usr/local, if it matters). * On MTD1 I should have U-Boot. * MTD2 and MTD3 should contain a "recovery copy" of kernel and RootFS (no Application). * U-Boot should have a notion of "current" and "known good" system and should try booting "current" a few times; if it fails it should try "known good"; if it still fails (e.g.: SD is completely broken) it should boot from "recovery" on SPI NOR. I've seen some `configs` (most notably theadorable-x86) seem to implement something like this, but, sincerely, I've been unable to divine what they're actually doing. If someone could be so kind to point me in the right direction... ;) Thanks in Advance Mauro

qemu_arm64_defconfig: PCI autoconfig fails for qemu-system-aarch64 -m 4G
by Heinrich Schuchardt 02 Jan '20

02 Jan '20

Dear all, I want to run qemu_arm64_defconfig with 4G. qemu-system-aarch64 -machine virt -m 4G -smp cores=2 \ -bios u-boot.bin -cpu cortex-a53 -nographic -gdb tcp::1234 \ -netdev user,id=eth0,tftp=tftp -device e1000,netdev=eth0 \ -device virtio-rng-pci I see an error: No working controllers found e1000: 52:54:00:12:34:56 Warning: e1000#0 using MAC address from ROM BOOTP broadcast 1 pci_hose_phys_to_bus: invalid physical address BOOTP broadcast 2 pci_hose_phys_to_bus: invalid physical address The error does not occur for a smaller RAM size. I added some debug output: _dm_pci_phys_to_bus: phys_addr 0x000000013ffecb40, res->phys_start 0x0000000010000000, res->bus_start 0x10000000 As qemu_arm64_defconfig does not define CONFIG_SYS_PCI_64BIT the calculated bus address is truncated. If CONFIG_SYS_PCI_64BIT is defined for qemu_arm64_defconfig and the memory is less then 4 GiB an error PCI: Failed autoconfig bar 10 occurs. For 3GiB memory I observed the following values: _dm_pci_phys_to_bus: phys_addr 0x00000000fffecbc0, res->phys_start 0x0000000010000000, res->bus_start 0x0000000010000000 When I define type pci_addr_t as 64bit everything works correctly. Why does the number of bits in pci_addr_t depend on CONFIG_SYS_PCI_64BIT and not on the bitness of the system? It is especially worrisome that CONFIG_SYS_PCI_64BIT is not documented at all. I wonder if Kumar remembers why he introduced it in 2008. I tried to change the definition of the following types in pci.h typedef phys_addr_t pci_addr_t; typedef phys_addr_t pci_size_t; This lets qemu-x86_defconfig fail with Error binding driver 'cpu_qemu': -12 Using typedef unsigned long pci_addr_t; typedef unsigned long pci_size_t; does not produce the error but I am not sure if this is the right approach. Best regards Heinrich

[PATCH 00/11] riscv: Add Sipeed Maix support

This patch series adds support for Sipeed Maix boards and the Kendryte K210 CPU. Currently, only the Maix Bit V2.0 is supported, however other models are similar.

[U-Boot] [PATCH v4 0/5] of-platdata: Avoid building libfdt
by Simon Glass 02 Jan '20

02 Jan '20

The original patch of this series was sent in September but unfortunately caused build problems on some boards, since they don't comply with the of-platdata rules. With of-platdata, the idea is to compile the device tree into C structures to save space and avoid needing to use libfdt. But some boards use of-platdata while also using libfdt in a few areas, thus defeating the purpose of of-platdata. This series includes the original two patches http://patchwork.ozlabs.org/patch/1167420/ http://patchwork.ozlabs.org/patch/1167367/ as well as a few other patches to fix the build errors. Overall this reduces code size and provides better error messages when unavailable functions are used. Board maintainers should still take a look at the result, adjusting the of-platdata support as needed. Changes in v4: - Add new patch for rockchip build errors - Add new patch for omap MMC build errors - Add new patch for rockchip chromebook build errors - Pull out patches into a new series - Add new patches to handle build failures Changes in v3: - Fix eth_dev_get_mac_address() call dev_read...() only when available Simon Glass (5): rockchip: Avoid using libfdt with of-platdata omap: mmc: Avoid using libfdt with of-platdata rockchip: pinctrl: Disable full pinctrl for SPL dm: core: Don't include ofnode functions with of-platdata spl: Allow SPL/TPL to use of-platdata without libfdt configs/chromebit_mickey_defconfig | 1 + configs/chromebook_jerry_defconfig | 1 + configs/chromebook_minnie_defconfig | 1 + configs/chromebook_speedy_defconfig | 1 + drivers/clk/rockchip/clk_rk3328.c | 14 ++++++++++++-- drivers/core/Makefile | 4 +++- drivers/mmc/davinci_mmc.c | 6 ++++++ drivers/pinctrl/rockchip/pinctrl-rockchip-core.c | 6 ++++-- include/dm/read.h | 3 +-- lib/Kconfig | 4 ++-- net/eth-uclass.c | 2 +- 11 files changed, 33 insertions(+), 10 deletions(-) -- 2.24.0.rc1.363.gb1bccd3e3d-goog

[PATCH] drivers: pci: initialise class to 0 before reading
by Hugh Cole-Baker 01 Jan '20

01 Jan '20

Otherwise, uninitialised memory from the upper 32 bits can end up in find_id.class, and this causes bugs later when looking for a driver for the class.

[PATCH v2 1/1] efi_loader: __cyg_profile_func_enter/_exit
by Heinrich Schuchardt 01 Jan '20

01 Jan '20

U-Boot can be compiled with function tracing enabled. When compiling with FTRACE __cyg_profile_func_enter() is called when a function is entered and __cyg_profile_func_exit() when the function is left. To avoid a crash we have to define these function for the free-standing UEFI binaries.
