[PATCH] ARM: imx6: Fetch MAC address in board_init_late() on DH iMX6 PDK2
by Marek Vasut 23 Jun '20

23 Jun '20

This is needed to obtain the MAC from EEPROM/OTP only after the final env is populated, otherwise the ethaddr might be overriden.

[PATCH 0/2] Enable all cache ways and Enable SiFive PWM driver
by Pragnesh Patel 23 Jun '20

23 Jun '20

Patch 1: enable all cache ways from U-Boot proper This patch enables all cache ways from U-Boot proper, earlier this was done by FSBL. (https://github.com/sifive/freedom-u540-c000-bootloader/blob/master/fsbl/mai…) L2 cache is of 2 MB (16 cache ways) and 1 cache way is of 128 KB. FSBL is located on the latest way of L2 cache. Therefore, FSBL can only enable the first 15 L2 cache ways to avoid corrupt itself. U-Boot proper enables all cache ways (16 cache ways) in this patch. Patch 2: Enable SiFive PWM driver This patch enables SiFive PWM driver for the SiFive Unleashed board. This series is rebase on - [v13] RISC-V SiFive FU540 support SPL This series depends on: [1] https://patchwork.ozlabs.org/patch/1275883 All these together is available for testing here [2] https://github.com/pragnesh26992/u-boot/tree/pwm Pragnesh Patel (2): riscv: sifive: fu540: enable all cache ways from U-Boot proper riscv: sifive: fu540: Enable SiFive PWM driver arch/riscv/cpu/fu540/Makefile | 1 + arch/riscv/cpu/fu540/cache.c | 53 +++++++++++++++++++++++ arch/riscv/dts/fu540-c000-u-boot.dtsi | 4 ++ arch/riscv/include/asm/arch-fu540/cache.h | 14 ++++++ board/sifive/fu540/Kconfig | 2 + board/sifive/fu540/fu540.c | 10 ++++- 6 files changed, 83 insertions(+), 1 deletion(-) create mode 100644 arch/riscv/cpu/fu540/cache.c create mode 100644 arch/riscv/include/asm/arch-fu540/cache.h -- 2.17.1

[ANN] U-Boot v2020.07-rc5 released
by Tom Rini 23 Jun '20

23 Jun '20

Hey all, It's release day and I've tagged v2020.07-rc5. There's been a few assorted bug fixes to come in, and -next is open. As far as I know, there's only some i.MX regression fixes to come in to fix ethernet in a few cases. Once again, for a changelog, git log --merges v2020.07-rc4..v2020.07-rc5 and as always, I ask for more details in the PRs people send me so I can put them in the merge commit. I'm going to continue with the every-other-week RC schedule and release on July 6th. Thanks all! -- Tom

[PATCH v1 0/7] Toradex: EEPROM storage support for Config Block
by Igor Opaniuk 22 Jun '20

22 Jun '20

This series introduces support for EEPROM as a storage for the main Toradex config block and additional config blocks on extra EEPROM chips (on carrier board or video adapters). To enable EEPROM as a storage for the main config block: TDX_HAVE_EEPROM=y. For additional EEPROMs please enable this Kconfig symbol: TDX_CFG_BLOCK_EXTRA=y. Information about existing EEPROM chips is provided via Device Tree using aliases. You can also write configuration for the carrier board using create_carrier subcommand for cfgblock. Example: Verdin iMX8MM # cfgblock create_carrier Supported carrier boards: UNKNOWN CARRIER = [0] Verdin Carrier Board = [1] Choose your carrier board (provide ID): 1 Enter carrier board version (e.g. V1.1B): V1.0A Enter carrier board serial number: 10622780 Also with barcode: Verdin iMX8MM # cfgblock create carrier -y 0156100010622780 Igor Opaniuk (7): toradex: tdx-cfg-block: add EEPROM read/store wrappers toradex: tdx-cfg-block: add carrier boards and display adapters toradex: tdx-cfg-block: add support for EEPROM toradex: tdx-cfg-clock: add migration routine from PID8 toradex: tdx-cfg-block: add carrier board info printing ARM: dts: imx8mm-verdin: eeprom nodes adjustments verdin-imx8mm: add EEPROM support for carrier board arch/arm/dts/imx8mm-verdin.dts | 22 +- board/toradex/common/Kconfig | 18 ++ board/toradex/common/Makefile | 1 + board/toradex/common/tdx-cfg-block.c | 402 +++++++++++++++++++++++++++++++---- board/toradex/common/tdx-cfg-block.h | 16 ++ board/toradex/common/tdx-common.c | 28 +++ board/toradex/common/tdx-eeprom.c | 90 ++++++++ board/toradex/common/tdx-eeprom.h | 14 ++ board/toradex/verdin-imx8mm/Kconfig | 6 + configs/verdin-imx8mm_defconfig | 1 + 10 files changed, 551 insertions(+), 47 deletions(-) create mode 100644 board/toradex/common/tdx-eeprom.c create mode 100644 board/toradex/common/tdx-eeprom.h -- 2.7.4

[PATCH 1/2] firmware: PSCI: Fix PSCI support for OF live trees
by Jon Hunter 22 Jun '20

22 Jun '20

When CONFIG_OF_LIVE is enabled, dev_of_offset() cannot be used and if used returns an invalid offset. This causes the call to fdt_stringlist_get() in the psci_probe() to fail to read the 'method' property from the PSCI node for the device and hence prevents PSCI from working. Fix this by using the ofnode_read_string() API instead of the fdt_stringlist_get() because this will handle reading the property both when CONFIG_OF_LIVE is enabled or disabled. Due to the above problem and since commit 81ea00838c68 ("efi_loader: PSCI reset and shutdown") was added, the EFI system reset has been broken for Tegra210 and Tegra196 platforms. This also fixes the EFI system reset for these Tegra platforms.

Out of bounds access in arch/arm/cpu/armv7/iproc-common/armpll.c
by Heinrich Schuchardt 22 Jun '20

22 Jun '20

Hello Scott, CppCheck gives an error: [arch/arm/cpu/armv7/iproc-common/armpll.c:137]: (error) Array 'armpll_clk_tab[13]' accessed at index 17, which is out of bounds. In the loop at the start of armpll_config() i is determined. The maximum value of i after checking status in line 53 is 12. In line 137 your code accesses armpll_clk_tab[i+4].freqid The patch where you introduced the code dates from 2014. But hopefully you still remember what you intended to do in that line. Best regards Heinrich
