[U-Boot] Difference between _defconfig and _config make switches
by Ahmad Ijaz 25 Jun '19

25 Jun '19

Hi Sir, I am trying to understand u-boot source code. As a starting point, I compiled u-boot for beaglebone black and successfully executed it on beaglebone hardware. My question is related to compilation step. The u-boot can be compiled with the following switches on *make.* *1. am335x_beaglebone_defconfig* *2. am335x_beaglebone_config* *3. am335x_evm_defconfig* *4. am335x_evm_config* All compiles fine. but whats the difference b/w " **_defconfig" AND " *_config". *Interestingly there are no script in the /config directory ending with *_config *(all ends with _defconfig). I tried to read the Makefile to find out if these switches may be pointing to a file but couldn't get it. Please give me a direction in this regard. Are they switches or name of configuration files? waiting for your kind reply. Kind regards, Ijaz

[U-Boot] [PATCH v3 0/7] efi_loader: non-volatile variables support
by AKASHI Takahiro 25 Jun '19

25 Jun '19

This patch set is an attempt to implement non-volatile attribute for UEFI variables. Under the current implementation, * SetVariable API doesn't recognize non-volatile attribute * While some variables are defined non-volatile in UEFI specification, they are NOT marked as non-volatile in the code. * env_save() (or "env save" command) allows us to save all the variables into persistent storage, but it may cause volatile UEFI variables, along with irrelevant U-Boot variables, to be saved unconditionally. Those observation rationalizes that the implementation of UEFI variables should be revamped utilizing dedicated storage for them. This patch set is yet experimental and rough-edged(See known issues below), but shows how UEFI variables can be split from U-Boot environment. Note: When StMM services is supported as a backing variables storage, efi_get_variable/efi_get_next_variable_name/efi_set_variable() will be replaced with stub functions to communicate with secure world. Usage: To enable this feature, the following configs must be enabled: CONFIG_ENV_IS_IN_FAT CONFIG_ENV_FAT_INTERFACE CONFIG_ENV_EFI_FAT_DEVICE_AND_PART CONFIG_ENV_EFI_FAT_FILE You can also define a non-volatile variable from command interface: => setenv -e -nv FOO baa Known issues/restriction/TODO: * UEFI spec defines "globally defined variables" with specific attributes, but with this patch, we don't check against the user-supplied attribute for any variable. * Only FAT can be enabled for persistent storage for UEFI non-volatile variables. * The whole area of storage will be saved at every update of one variable. It can be optimized. * An error during saving may cause inconsistency between cache (hash table) and the storage. * Cache is of fixed size and can be quite big for normal usage. * I still see some Travis CI errors. Patch#1 to #4 are core part of changes. Patch#5 to #6 are to change some existing variables' attributes. Patch#7 is to extend env command for non-volatile variables. Changes in v3 (Jun 4, 2019) * remove already-merged patches * revamp the code again * introduce CONFIG_EFI_VARIABLE_USE_ENV for this configuration. Once another backing storage, i.e. StMM services for secure boot, is supported, another option will be added. Changes in v2 (Apr 24, 2019) * rebased on efi-2019-07 * revamp the implementation v1 (Nov 28, 2018) * initial AKASHI Takahiro (7): env: save UEFI non-volatile variables in dedicated storage efi_loader: variable: support non-volatile attribute efi_loader: variable: split UEFI variables from U-Boot environment efi_loader: load saved non-volatile variables at init efi_loader: bootmgr: make BootNext non-volatile cmd: efidebug: make some boot variables non-volatile cmd: env: add -nv option for UEFI non-volatile variable cmd/efidebug.c | 3 + cmd/nvedit.c | 3 +- cmd/nvedit_efi.c | 15 +- env/Kconfig | 39 ++++ env/env.c | 155 ++++++++++++- env/fat.c | 105 +++++++++ include/asm-generic/global_data.h | 3 + include/environment.h | 31 +++ lib/efi_loader/Kconfig | 10 + lib/efi_loader/efi_bootmgr.c | 3 +- lib/efi_loader/efi_setup.c | 6 + lib/efi_loader/efi_variable.c | 354 +++++++++++++++++++++++------- 12 files changed, 641 insertions(+), 86 deletions(-) -- 2.21.0

[U-Boot] [PATCH v8 0/9] Update SiFive Unleashed Drivers
by Anup Patel 25 Jun '19

25 Jun '19

This series update SiFive Unleashed clock driver and Cadence MACB driver so that: 1. It is in sync with upstream Linux driver 2. It uses latest DT bindings as-per upstream Linux driver With this series, we can now use latest DT bindings with U-Boot. I have tested SiFive Serial driver and Cadence MACB ethernet driver with this changes and both work fine. The legacy FSBL will still pass DTB with older DT bindings which will break the updated SiFive Unleashed clock driver. To tackle this, we have embedded DTB in OpenSBI FW_PAYLOAD firmware for SiFive Unleashed so that OpenSBI will override and pass updated DTB to U-Boot. The updated DTB passed by OpenSBI is in fact the DTB build by upstream Linux so we can straight away pass this DTB to Linux as well. This series can be found in riscv_unleashed_clk_sync_v8 branch at: https://github.com/avpatel/u-boot.git To try this series use latest OpenSBI at: https://github.com/riscv/opensbi.git And Linux-5.2-rc1 from v5.2-rc1_unleashed branch at: https://github.com/avpatel/linux.git Changes since v7: - Update PATCH6 to not treat dma_burst_length = 0 as skip gmac_configure_dma() - Update PATCH9 to check endianess at runtime Changes since v6: - Added separate patch to fix endianess check in gmac_configure_dma() Changes since v5: - Addressed Ramon's comments in PATCH6 - Addressed Bin's comments in PATCH7 Changes since v4: - Rebased patches upon Ramon's MACB changes (Refer, https://patchwork.ozlabs.org/patch/1114025/) - Added PATCH7 to setup ethaddr based on board serial number read from OTP - Added PATCH8 to update documentation Changes since v3: - Extend MACB ethernet driver for SiFive Unleashed board (just like Linux) Changes since v2: - Dropped PATCH6 which adds new compatible string to MACB driver because more changes are required in MACB driver for different ethernet speeds Changes since v1: - Dropped GEMGXL clock driver - Added new compatible string for SiFive MACB ethernet Anup Patel (9): clk: sifive: Factor-out PLL library as separate module clk: sifive: Sync-up WRPLL library with upstream Linux clk: sifive: Sync-up DT bindings header with upstream Linux clk: sifive: Sync-up main driver with upstream Linux clk: sifive: Drop GEMGXL clock driver net: macb: Extend MACB driver for SiFive Unleashed board riscv: sifive: fu540: Setup ethaddr env variable using OTP doc: sifive-fu540: Update README for steps to create FW_PAYLOAD net: macb: Fix check for little-endian system in gmac_configure_dma() board/sifive/fu540/Kconfig | 1 - board/sifive/fu540/fu540.c | 122 ++++++ configs/sifive_fu540_defconfig | 1 + doc/README.sifive-fu540 | 356 ++++++++---------- drivers/clk/Kconfig | 1 + drivers/clk/Makefile | 1 + drivers/clk/analogbits/Kconfig | 4 + drivers/clk/analogbits/Makefile | 3 + .../{sifive => analogbits}/wrpll-cln28hpc.c | 168 ++++----- drivers/clk/sifive/Kconfig | 10 - drivers/clk/sifive/Makefile | 4 - drivers/clk/sifive/fu540-prci.c | 123 +++--- drivers/clk/sifive/gemgxl-mgmt.c | 60 --- drivers/net/macb.c | 98 +++-- include/dt-bindings/clk/sifive-fu540-prci.h | 29 -- include/dt-bindings/clock/sifive-fu540-prci.h | 18 + .../linux/clk}/analogbits-wrpll-cln28hpc.h | 70 ++-- 17 files changed, 559 insertions(+), 510 deletions(-) create mode 100644 drivers/clk/analogbits/Kconfig create mode 100644 drivers/clk/analogbits/Makefile rename drivers/clk/{sifive => analogbits}/wrpll-cln28hpc.c (69%) delete mode 100644 drivers/clk/sifive/gemgxl-mgmt.c delete mode 100644 include/dt-bindings/clk/sifive-fu540-prci.h create mode 100644 include/dt-bindings/clock/sifive-fu540-prci.h rename {drivers/clk/sifive => include/linux/clk}/analogbits-wrpll-cln28hpc.h (52%) -- 2.17.1

[U-Boot] Fwd: Crash in U-Boot
by Heinrich Schuchardt 24 Jun '19

24 Jun '19

Hello Alex, on the i.MX6 Wandboard the Kernel crashes when booting via GRUB at least since U-Boot v2019.01. See below. In the code for SetVirtualAddressMap I saw the that the pointer to the list of configuration tables is adjusted: if ((map_start <= (uintptr_t)systab.tables) && (map_end >= (uintptr_t)systab.tables)) { char *ptr = (char *)systab.tables; ptr += off; systab.tables = (struct efi_configuration_table *)ptr; } Shouldn't the pointers to the individual configuration tables be adjusted too? I found no such code.
