[RFC PATCH 0/1] tools: mkimage: Add Allwinner TOC1 support
by Samuel Holland 15 Oct '21

15 Oct '21

The SPL port for the Allwinner D1 RISC-V SoC will probably take a while longer than porting U-Boot proper, as none of the relevant drivers are set up for DM in SPL. In the meantime, we are using[1][2] a fork[3] of Allwinner's boot0 loader, which they also call "spl" in their BSP. boot0 uses this TOC1 image format. The vendor tools for generating TOC1 images require a binary config file generated by their FEX compiler. Instead of trying to support that, I made up a simple human-readable config file format. I didn't see any existing platform-agnostic parser for multi-image containers in mkimage. I am sending this as RFC because it is only of temporary/limited use. It only works with one specific fork of boot0 which was modified to "behave" (the the original vendor version monkey-patches a custom header inside the U-Boot image during boot). So it will be obsolete once U-Boot SPL is ported. And it is Yet Another Image Format. On the other hand, it does work, and it is currently being used.

[PATCH next v5 00/12] aspeed: Support secure boot chain with FIT image verification
by Chia-Wei Wang 15 Oct '21

15 Oct '21

This patch series intends to provide a secure boot chain from SPL to Linux kernel based on the hash and signature verification of FIT image paradigm. To improve the performance and save code size (SPL is limited to 64KB due to HW-RoT), the drviers of two HW crypto engine HACE and ACRY are also added for AST26xx SoCs. As HACE and ACRY can only access to DRAM space, additional configuration and boot command are also updated according to move each FIT image before its booting. In addition, the common code of FIT image hash algorithm lookup is also revised to leverage the HW accelerated calculation. v5: - fix inconsistent parameter name due to parallel patch work v4: - add new DM_HASH based driver for Aspeed HACE - remove SPL board init, which was originally used to probe non-DM HACE driver - fix typo of ARCY to ACRY - refactor defconfig based on the new Kconfig of U-Boot next branch v3: - add SW work around for HACE HW DMA issue by resetting HACE - add reset control for HACE device tree node - sync all of the HACE error message to use debug() v2: - update commit authors Chia-Wei Wang (9): image: fit: Fix parameter name for hash algorithm aspeed: ast2600: Enlarge SRAM size clk: ast2600: Add RSACLK control for ACRY crypto: aspeed: Add AST2600 ACRY support ARM: dts: ast2600: Add ACRY to device tree ast2600: spl: Locate load buffer in DRAM space configs: ast2600-evb: Enable SPL FIT support configs: aspeed: Make EXTRA_ENV_SETTINGS board specific configs: ast2600: Boot kernel FIT in DRAM Joel Stanley (2): clk: ast2600: Add YCLK control for HACE ARM: dts: ast2600: Add HACE to device tree Johnny Huang (1): crypto: aspeed: Add AST2600 HACE support arch/arm/dts/ast2600-evb.dts | 10 + arch/arm/dts/ast2600.dtsi | 17 + arch/arm/include/asm/arch-aspeed/platform.h | 2 +- .../arm/include/asm/arch-aspeed/scu_ast2600.h | 6 +- arch/arm/mach-aspeed/ast2600/spl.c | 9 +- common/image-fit.c | 2 +- configs/evb-ast2600_defconfig | 22 +- drivers/clk/aspeed/clk_ast2600.c | 38 ++ drivers/crypto/Kconfig | 2 + drivers/crypto/Makefile | 1 + drivers/crypto/aspeed/Kconfig | 20 + drivers/crypto/aspeed/Makefile | 2 + drivers/crypto/aspeed/aspeed_acry.c | 182 +++++++++ drivers/crypto/aspeed/aspeed_hace.c | 381 ++++++++++++++++++ drivers/crypto/hash/Kconfig | 8 + include/configs/aspeed-common.h | 9 - include/configs/evb_ast2500.h | 9 + include/configs/evb_ast2600.h | 16 + lib/rsa/Kconfig | 10 +- 19 files changed, 720 insertions(+), 26 deletions(-) create mode 100644 drivers/crypto/aspeed/Kconfig create mode 100644 drivers/crypto/aspeed/Makefile create mode 100644 drivers/crypto/aspeed/aspeed_acry.c create mode 100644 drivers/crypto/aspeed/aspeed_hace.c -- 2.17.1

This initial series provides support for the serial port, framebuffer and the USB 3.1 Type-C ports. It can boot a support OS (e.g. OpenBSD/arm64) from a USB disk. This version attempts to address most comments. It doesn't add a proper WDT/sysreset driver yet since I prefer to do that once the device tree bindings for that have been ironed out. ChangeLog: v2: - Add IOMMU uclass and use it for the DART driver - Cut back DART driver to only support bypass mode - Rework the S5P serial support to use more DT stuff - Update preliminary device trees v3: - Respin for CONFIG_SYS_LOAD_ADDR kconfig migration Mark Kettenis (7): iommu: Add IOMMU uclass test: Add tests for IOMMU uclass arm: apple: Add initial support for Apple's M1 SoC serial: s5p: Add Apple M1 support iommu: Add Apple DART driver arm: dts: apple: Add preliminary device trees doc: board: apple: Add Apple M1 documentation arch/arm/Kconfig | 23 + arch/arm/Makefile | 1 + arch/arm/dts/Makefile | 4 + arch/arm/dts/t8103-j274.dts | 135 +++++ arch/arm/dts/t8103-j293.dts | 97 +++ arch/arm/dts/t8103.dtsi | 560 ++++++++++++++++++ arch/arm/include/asm/arch-m1/uart.h | 41 ++ arch/arm/mach-apple/Kconfig | 18 + arch/arm/mach-apple/Makefile | 4 + arch/arm/mach-apple/board.c | 161 +++++ arch/arm/mach-apple/lowlevel_init.S | 17 + arch/sandbox/dts/test.dts | 6 + configs/apple_m1_defconfig | 20 + configs/sandbox64_defconfig | 1 + configs/sandbox_defconfig | 1 + configs/sandbox_flattree_defconfig | 1 + configs/sandbox_noinst_defconfig | 1 + configs/sandbox_spl_defconfig | 1 + doc/board/apple/index.rst | 9 + doc/board/apple/m1.rst | 56 ++ doc/board/index.rst | 1 + drivers/Kconfig | 2 + drivers/Makefile | 1 + drivers/core/device.c | 8 + drivers/iommu/Kconfig | 23 + drivers/iommu/Makefile | 6 + drivers/iommu/apple_dart.c | 59 ++ drivers/iommu/iommu-uclass.c | 45 ++ drivers/iommu/sandbox_iommu.c | 18 + drivers/serial/Kconfig | 4 +- drivers/serial/serial_s5p.c | 104 +++- include/configs/apple.h | 36 ++ include/dm/uclass-id.h | 1 + .../interrupt-controller/apple-aic.h | 15 + include/dt-bindings/pinctrl/apple.h | 13 + include/dt-bindings/spmi/spmi.h | 10 + include/iommu.h | 16 + test/dm/Makefile | 1 + test/dm/iommu.c | 28 + 39 files changed, 1524 insertions(+), 24 deletions(-) create mode 100644 arch/arm/dts/t8103-j274.dts create mode 100644 arch/arm/dts/t8103-j293.dts create mode 100644 arch/arm/dts/t8103.dtsi create mode 100644 arch/arm/include/asm/arch-m1/uart.h create mode 100644 arch/arm/mach-apple/Kconfig create mode 100644 arch/arm/mach-apple/Makefile create mode 100644 arch/arm/mach-apple/board.c create mode 100644 arch/arm/mach-apple/lowlevel_init.S create mode 100644 configs/apple_m1_defconfig create mode 100644 doc/board/apple/index.rst create mode 100644 doc/board/apple/m1.rst create mode 100644 drivers/iommu/Kconfig create mode 100644 drivers/iommu/Makefile create mode 100644 drivers/iommu/apple_dart.c create mode 100644 drivers/iommu/iommu-uclass.c create mode 100644 drivers/iommu/sandbox_iommu.c create mode 100644 include/configs/apple.h create mode 100644 include/dt-bindings/interrupt-controller/apple-aic.h create mode 100644 include/dt-bindings/pinctrl/apple.h create mode 100644 include/dt-bindings/spmi/spmi.h create mode 100644 include/iommu.h create mode 100644 test/dm/iommu.c -- 2.33.0
