From: Rayagonda Kokatanur <rayagonda.kokatanur(a)broadcom.com> IPROC qspi driver supports both BSPI and MSPI modes. Signed-off-by: Rayagonda Kokatanur <rayagonda.kokatanur(a)broadcom.com> Signed-off-by: Bharat Gooty <bharat.gooty(a)broadcom.com> Acked-by: Rayagonda Kokatanur <rayagonda.kokatanur(a)broadcom.com> Signed-off-by: Roman Bacik <roman.bacik(a)broadcom.com> --- Changes in v4: - move iproc_qspi.c from spi to mtd/spi - remove iproc_qspi.h - rename IPROC_QSPI to SPI_FLASH_IPROC Changes in v3: - fix warning by including linux/delay.h - change ofdata_to_platdata to of_to_plat - change priv_auto_alloc_size to priv_auto Changes in v2: - remove include spi-nor.h - define and use named BITs for writing register values - remove bspi_set_4byte_mode() method drivers/mtd/spi/Kconfig | 6 + drivers/mtd/spi/Makefile | 1 + drivers/mtd/spi/iproc_qspi.c | 718 +++++++++++++++++++++++++++++++++++ 3

[PATCH 00/16] fdt: Make OF_BOARD a boolean option
by Simon Glass 02 Nov '21

02 Nov '21

With Ilias' efforts we have dropped OF_PRIOR_STAGE and OF_HOSTFILE so there are only three ways to obtain a devicetree: - OF_SEPARATE - the normal way, where the devicetree is built and appended to U-Boot - OF_EMBED - for development purposes, the devicetree is embedded in the ELF file (also used for EFI) - OF_BOARD - the board figures it out on its own The last one is currently set up so that no devicetree is needed at all in the U-Boot tree. Most boards do provide one, but some don't. Some don't even provide instructions on how to boot on the board. The problems with this approach are documented at [1]. In practice, OF_BOARD is not really distinct from OF_SEPARATE. Any board can obtain its devicetree at runtime, even it is has a devicetree built in U-Boot. This is because U-Boot may be a second-stage bootloader and its caller may have a better idea about the hardware available in the machine. This is the case with a few QEMU boards, for example. So it makes no sense to have OF_BOARD as a 'choice'. It should be an option, available with either OF_SEPARATE or OF_EMBED. This series makes this change, adding various missing devicetree files (and placeholders) to make the build work. It also provides a few qemu clean-ups discovered along the way. This series is based on Ilias' two series for OF_HOSTFILE and OF_PRIOR_STAGE removal. It is available at u-boot-dm/ofb-working [1] https://patchwork.ozlabs.org/project/uboot/patch/20210919215111.3830278-3-s… Simon Glass (16): arm: qemu: Mention -nographic in the docs arm: qemu: Explain how to extract the generate devicetree riscv: qemu: Explain how to extract the generate devicetree arm: qemu: Add a devicetree file for qemu_arm arm: qemu: Add a devicetree file for qemu_arm64 riscv: qemu: Add devicetree files for qemu_riscv32/64 arm: rpi: Add a devicetree file for rpi_4 arm: vexpress: Add a devicetree file for juno arm: xenguest_arm64: Add a fake devicetree file arm: octeontx: Add a fake devicetree file arm: xilinx_versal_virt: Add a devicetree file arm: bcm7xxx: Add a devicetree file arm: qemu-ppce500: Add a devicetree file arm: highbank: Add a fake devicetree file fdt: Make OF_BOARD a bool option Drop CONFIG_BINMAN_STANDALONE_FDT Makefile | 3 +- arch/arm/dts/Makefile | 20 +- arch/arm/dts/bcm2711-rpi-4-b.dts | 1958 ++++++++++++++++++++++++ arch/arm/dts/bcm7xxx.dts | 15 + arch/arm/dts/highbank.dts | 14 + arch/arm/dts/juno-r2.dts | 1038 +++++++++++++ arch/arm/dts/octeontx.dts | 14 + arch/arm/dts/qemu-arm.dts | 402 +++++ arch/arm/dts/qemu-arm64.dts | 381 +++++ arch/arm/dts/xenguest-arm64.dts | 15 + arch/arm/dts/xilinx-versal-virt.dts | 307 ++++ arch/powerpc/dts/Makefile | 1 + arch/powerpc/dts/qemu-ppce500.dts | 264 ++++ arch/riscv/dts/Makefile | 2 +- arch/riscv/dts/qemu-virt.dts | 8 - arch/riscv/dts/qemu-virt32.dts | 217 +++ arch/riscv/dts/qemu-virt64.dts | 217 +++ configs/bcm7260_defconfig | 1 + configs/bcm7445_defconfig | 1 + configs/highbank_defconfig | 2 +- configs/octeontx2_95xx_defconfig | 1 + configs/octeontx2_96xx_defconfig | 1 + configs/octeontx_81xx_defconfig | 1 + configs/octeontx_83xx_defconfig | 1 + configs/qemu-ppce500_defconfig | 2 + configs/qemu-riscv32_defconfig | 1 + configs/qemu-riscv32_smode_defconfig | 1 + configs/qemu-riscv32_spl_defconfig | 4 +- configs/qemu-riscv64_defconfig | 1 + configs/qemu-riscv64_smode_defconfig | 1 + configs/qemu-riscv64_spl_defconfig | 3 +- configs/qemu_arm64_defconfig | 1 + configs/qemu_arm_defconfig | 1 + configs/rpi_4_32b_defconfig | 1 + configs/rpi_4_defconfig | 1 + configs/rpi_arm64_defconfig | 1 + configs/vexpress_aemv8a_juno_defconfig | 1 + configs/xenguest_arm64_defconfig | 1 + configs/xilinx_versal_virt_defconfig | 1 + doc/board/emulation/qemu-arm.rst | 19 +- doc/board/emulation/qemu-riscv.rst | 12 + dts/Kconfig | 27 +- tools/binman/binman.rst | 20 - 43 files changed, 4922 insertions(+), 61 deletions(-) create mode 100644 arch/arm/dts/bcm2711-rpi-4-b.dts create mode 100644 arch/arm/dts/bcm7xxx.dts create mode 100644 arch/arm/dts/highbank.dts create mode 100644 arch/arm/dts/juno-r2.dts create mode 100644 arch/arm/dts/octeontx.dts create mode 100644 arch/arm/dts/qemu-arm.dts create mode 100644 arch/arm/dts/qemu-arm64.dts create mode 100644 arch/arm/dts/xenguest-arm64.dts create mode 100644 arch/arm/dts/xilinx-versal-virt.dts create mode 100644 arch/powerpc/dts/qemu-ppce500.dts delete mode 100644 arch/riscv/dts/qemu-virt.dts create mode 100644 arch/riscv/dts/qemu-virt32.dts create mode 100644 arch/riscv/dts/qemu-virt64.dts -- 2.33.0.882.g93a45727a2-goog

[PATCH v2] arm: xea: Modify board code to generate single binary u-boot
by Lukasz Majewski 02 Nov '21

02 Nov '21

This change provides the possibility to build XEA (imx287 based) board U-Boot as a single binary (without support for CONFIG_SPL_FRAMEWORK). The generated u-boot.sb can be used in the factory environment to for example perform initial setup or HW testing. It can be used with 'uuu' utility (SDPS: boot -f /srv/tftp/xea/u-boot.sb) In the configs/imx28_xea_defconfig one needs to disable following configs: # CONFIG_SPL_BLK is not set # CONFIG_SPL_FRAMEWORK is not set The board_init_ll() is used in arch/arm/cpu/arm926ejs/mxs/start.S, which is utilized when CONFIG_SPL_FRAMEWORK is disabled. However, when it is enabled - the arch/arm/cpu/arm926ejs/start.S is used, which requires the lowlevel_init() function. Signed-off-by: Lukasz Majewski <lukma(a)denx.de> --- Changes in v2: - Use CONFIG_IS_ENABLED(FRAMEWORK) instead of #ifdef CONFIG_SPL_FRAMEWORK (previous version used CONFIG_IS_ENABLED(SPL_FRAMEWORK), which was wrong). - Restructure spl_xea.c code to be more readable board/liebherr/xea/spl_xea.c | 8 ++++++++ board/liebherr/xea/xea.c | 3 ++- 2 files changed, 10 insertions(+), 1 deletion(-) diff --git a/board/liebherr/xea/spl_xea.c b/board/liebherr/xea/spl_xea.c index 192f68fca5f..5ee561b8b78 100644 --- a/board/liebherr/xea/spl_xea.c +++ b/board/liebherr/xea/spl_xea.c @@ -290,6 +290,13 @@ u32 mxs_dram_vals[] = { 0x00000000, 0xffffffff }; +/* #ifndef CONFIG_SPL_FRAMEWORK */ +#if !CONFIG_IS_ENABLED(FRAMEWORK) +void board_init_ll(const u32 arg, const uint32_t *resptr) +{ + mxs_common_spl_init(arg, resptr, iomux_setup, ARRAY_SIZE(iomux_setup)); +} +#else void lowlevel_init(void) { struct mxs_pinctrl_regs *pinctrl_regs = @@ -301,3 +308,4 @@ void lowlevel_init(void) mxs_common_spl_init(0, NULL, iomux_setup, ARRAY_SIZE(iomux_setup)); } +#endif diff --git a/board/liebherr/xea/xea.c b/board/liebherr/xea/xea.c index cd11b0ada77..685e2e26a18 100644 --- a/board/liebherr/xea/xea.c +++ b/board/liebherr/xea/xea.c @@ -58,7 +58,8 @@ static void init_clocks(void) mxs_set_sspclk(MXC_SSPCLK3, 96000, 0); } -#ifdef CONFIG_SPL_BUILD +/* #if CONFIG_SPL_BUILD && CONFIG_SPL_FRAMEWORK */ +#if CONFIG_IS_ENABLED(BUILD) && CONFIG_IS_ENABLED(FRAMEWORK) void board_init_f(ulong arg) { init_clocks(); -- 2.20.1

[PATCH] efi_loader: add EFI_TCG2_PROTOCOL.SubmitCommand
by Masahisa Kojima 02 Nov '21

02 Nov '21

This commit adds the EFI_TCG2_PROTOCOL.SubmitCommand required in the TCG PC Client PFP spec. SubmitCommand enables to send the raw command to the TPM device. To implement this api, tpm2_submit_command() is added into tpm-v2.c.

[PATCH v3 0/5] Fix compiler warnings for 32-bit ARM
by Simon Glass 01 Nov '21

01 Nov '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 So this series adds that. It also fixes the unicode warnings 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 as suggested by Heinrich. Changes in v3: - Mention the link to the new upstream patch - Change some things EFI things missed (or new since) last time - Use 'bitness' instead of 'bit' - Add a new patch to change non-EFI occurences Changes in v2: - Add new patch to reduce checkpatch unicode-string spam - Drop patches previously applied - Put all the packages in gcc.rst Joe Perches (1): checkpatch: Support wide strings Simon Glass (4): efi: Use 16-bit unicode strings sandbox: Detect the host bit size automatically treewide: Use 16-bit unicode strings RFC: treewide: Drop -fshort-char Makefile | 13 ++- arch/arm/config.mk | 2 +- arch/sandbox/Kconfig | 13 ++- arch/x86/config.mk | 2 +- arch/x86/cpu/Makefile | 2 +- arch/x86/lib/Makefile | 6 +- cmd/efidebug.c | 12 +- include/efi_loader.h | 2 +- include/efi_selftest.h | 4 +- lib/efi/Makefile | 4 +- lib/efi_loader/efi_bootmgr.c | 12 +- lib/efi_loader/efi_boottime.c | 2 +- lib/efi_loader/efi_capsule.c | 20 ++-- lib/efi_loader/efi_helper.c | 2 +- lib/efi_loader/efi_image_loader.c | 8 +- lib/efi_loader/efi_setup.c | 20 ++-- lib/efi_loader/efi_signature.c | 4 +- lib/efi_loader/efi_string.c | 2 +- lib/efi_loader/efi_var_common.c | 14 +-- lib/efi_loader/efi_variable.c | 6 +- lib/efi_loader/efi_variable_tee.c | 2 +- lib/efi_loader/helloworld.c | 40 +++---- lib/efi_selftest/dtbdump.c | 82 +++++++------- lib/efi_selftest/efi_selftest.c | 2 +- lib/efi_selftest/efi_selftest_block_device.c | 6 +- lib/efi_selftest/efi_selftest_devicepath.c | 2 +- lib/efi_selftest/efi_selftest_exception.c | 2 +- lib/efi_selftest/efi_selftest_fdt.c | 6 +- lib/efi_selftest/efi_selftest_hii.c | 8 +- lib/efi_selftest/efi_selftest_load_file.c | 4 +- lib/efi_selftest/efi_selftest_loadimage.c | 4 +- .../efi_selftest_miniapp_exception.c | 4 +- lib/efi_selftest/efi_selftest_miniapp_exit.c | 8 +- .../efi_selftest_miniapp_return.c | 2 +- lib/efi_selftest/efi_selftest_reset.c | 2 +- lib/efi_selftest/efi_selftest_textoutput.c | 12 +- .../efi_selftest_unicode_collation.c | 38 +++---- lib/efi_selftest/efi_selftest_util.c | 106 +++++++++--------- lib/efi_selftest/efi_selftest_variables.c | 22 ++-- .../efi_selftest_variables_runtime.c | 4 +- lib/efi_selftest/initrddump.c | 60 +++++----- lib/lzma/Types.h | 4 +- scripts/checkpatch.pl | 7 +- scripts/kconfig/Makefile | 14 ++- test/print_ut.c | 2 +- test/unicode_ut.c | 22 ++-- 46 files changed, 320 insertions(+), 295 deletions(-) -- 2.32.0.554.ge1b32706d8-goog
