[PATCH] sandbox: add FAT to the list of usable env drivers
by Heinrich Schuchardt 16 Mar '21

16 Mar '21

Add the FAT environment driver to the priority list. When testing the UEFI sub-system the EFI system partition is formatted with FAT so it is reasonable to store the environment there.

[PATCH v2 00/14] spi: dw: Add support for DUAL/QUAD/OCTAL modes
by Sean Anderson 16 Mar '21

16 Mar '21

This series adds support for enhanced SPI modes. It was tested on a K210 (DWC SSI with QSPI flash). If anyone has a designware device with QSPI flash attached (especially a DW SSI APB device), I'd greatly appreciate them testing out this patch series. Many of the earlier patches in this series are general fixups and can be split off/merged separately if desired. Changes in v2: - Add more information to exec_op debug message - Actually mask interrupts - Merge CAP_{DUAL,QUAD,OCTAL} into CAP_ENHANCED - Fix some inconsistencies in register naming and usage - Moved some hunks between commits so things make more sense Sean Anderson (14): cmd: sf: Display errno on erase failure cmd: sf: Print error on test failure mtd: spi-nor-core: Fix typo in documentation mtd: spi-mem: Export spi_mem_default_supports_op spi: spi-mem: Add debug message for spi-mem ops spi: dw: Log status register on timeout spi: dw: Actually mask interrupts spi: dw: Switch to capabilities spi: dw: Rewrite poll_transfer logic spi: dw: Add ENHANCED cap spi: dw: Define registers for enhanced mode spi: dw: Support enhanced SPI spi: dw: Support clock stretching riscv: k210: Enable QSPI for spi3 arch/riscv/dts/k210-maix-bit.dts | 2 + cmd/sf.c | 29 +- drivers/spi/designware_spi.c | 647 +++++++++++++++++++++---------- drivers/spi/spi-mem.c | 7 + include/linux/mtd/spi-nor.h | 2 +- include/spi-mem.h | 3 + 6 files changed, 472 insertions(+), 218 deletions(-) -- 2.29.2

[PATCH 0/7] Add FU740 chip and HiFive Unmatched board support
by Green Wan 16 Mar '21

16 Mar '21

This patch set is to add SiFive fu740 chip and HiFive Unmatched board support. Patches are split into several parts: - [PATCH 1/7] dts for fu740 - [PATCH 2/7] support for fu740 cpu - [PATCH 3/7, 4/7] support for fu740 clk and ram - [PATCH 5/7] add pcie driver - [PATCH 6/7] add unmatched board - [PATCH 7/7] add fu740 support to macb driver Description - For fu740 cpu support, reuse most of fu540 cpu. - For prci driver, add one abstract layer to separate fu540 and fu740. Move orignal fu540 code to separate files. - For pcie driver, it depends on gpio, prci, clk and reset drivers to do init&reset works. - Align with Linux DT file. Tests and patch checks - Able to boot both unmatched and unleashed boards. - PCIe tests . M.2 NVMe SSD . e1000 compatibale ethernet adapter (ping&tftpboot) . pci-to-usb adapter(usb mass storage) - checkpatch is performed. To keep code derived from other boards the same, ignore some warnings/errors in [PATCH 6/7].

[PATCH] bus: ti-sysc: fix uclass driver id
by Dario Binacchi 16 Mar '21

16 Mar '21

The module defines a duplicate uclass driver for UCLASS_SIMPLE_BUS, but it is not allowed. This breaks of-platdata and makes the result non-deterministic. Since it must be an uclass driver to work properly, a new class id has been added.

[PATCH u-boot v2 00/38] U-Boot LTO (Sandbox + Some ARM boards)
by Marek Behún 15 Mar '21

15 Mar '21

Hello, I am sending version 2 of patches adding support for LTO to U-Boot. This series was tested by Github/Azure CI at https://github.com/u-boot/u-boot/pull/57 Code reduction is on average 4.23% for u-boot.bin and 13.58% for u-boot-spl.bin. I am currently running a build test for all 1077 ARM defconfigs. Of the first 232 defconfigs, 2 are failing when LTO is enabled (chromebook_jerry and chromebook_speedy). Note that this series only enables LTO for tested boards. Changes since v1: - remove patches applied into u-boot-marvell - added Reviewed-by tags - addressed some issues discovered by Bin Meng, Marek Vasut, Heinrich Schuchardt - added more ARM boards (thanks to Adam Ford, Tim Harvey and Bin Meng) - removed --gc-sections for ARM if internal libgcc is used - remove -fwhole-program in final LTO LDFLAGS - declared all 4 functions (memcpy, memset, memcmp, memmove) __used, (these are mentioned in GCC man page for option -nodefaultlibs that the compiler may generate; this seems to be a bug in GCC that linking fails with LTO even if these functions are present, because the symbols can be renamed on some targets by optimization) Marek Marek Behún (38): regmap: fix a serious pointer casting bug api: fix a potential serious bug caused by undef CONFIG_SYS_64BIT_LBA checkpatch: require quotes around section name in the __section() macro treewide: Convert macro and uses of __section(foo) to __section("foo") compiler.h: align the __ADDRESSABLE macro with Linux' version linker_lists: prepare macros to avoid code repetition test/py: improve regular expression for ut subtest symbol matcher linker_lists: declare lists and entries as

[PATCH v9 0/5] Add RZ/G2[HMN] board support
by Biju Das 15 Mar '21

15 Mar '21

This patch series adds the required SoC/Board support to boot HopeRun HiHope RZ/G2[HMN] boards. Board identification support for supporting multidtb is derived from TF-A blob. V8-->v9 * Use tf-a blob for identifying board type.

[PATCH 0/7] Fix compiler warnings for 32-bit ARM
by Simon Glass 15 Mar '21

15 Mar '21

These were noticed when building sandbox on a Raspberry Pi 400, which uses 32-bit linux. To make this work, I enabled CONFIG_HOST_32BIT in 'make menuconfig'. It would be nice if that were automatic, since we have the logic already in arch/sandbox/config.mk There are still many errors of the form: /usr/bin/ld: warning: arch/sandbox/cpu/start.o uses 2-byte wchar_t yet the output is to use 4-byte wchar_t; use of wchar_t values across objects may fail I am not sure how to fix those, but they are not fatal (sandbox still runs). Simon Glass (7): mkeficapsule: Correct printf() strings efi: Fix compiler warnings pci: swap_case: Allow compilation on 32-bit machines tpm: Correct warning on 32-bit build test: acpi: Fix warnings on 32-bit build doc: sandbox: Fix up dependencies doc: sandbox: Update instructions on quitting cmd/efidebug.c | 2 +- doc/arch/sandbox.rst | 11 ++++++----- drivers/misc/swap_case.c | 13 +++++++++++-- drivers/tpm/tpm2_tis_sandbox.c | 2 +- lib/efi_loader/efi_capsule.c | 4 ++-- lib/efi_loader/efi_firmware.c | 4 ++-- test/dm/acpi.c | 12 ++++++------ tools/mkeficapsule.c | 14 +++++++------- 8 files changed, 36 insertions(+), 26 deletions(-) -- 2.30.0.478.g8a0d178c01-goog
