Various issues were discovered in getting Chromium OS verified boot running on top of coreboot, booting into U-Boot.
Improvements include: - enable serial console if even coreboot doesn't - enable cache always - show the BIOS date since Chromium OS's coreboot doesn't have a version - update docs - allow SPI driver to work without a PCH - fix mtrr command when multi-processing (CONFIG_MP) is disabled - add documentation about the memory map Changes in v2: - Add a comment about the cases - Reorder declaration and use bios_date for the variable name - Add missing newline in the error path - Use (ret) instead of (ret != 0) to fit with U-Boot style - Convert table to reST format - Add 'cros' tag since this not a generic x86 change - Drop unnecessary patch 'Enable the cbsysinfo command' Simon Glass (16): pci: Use const for pci_find_device_id() etc. x86: pci: Allow binding of some devices before relocation x86: Allow coreboot serial driver to guess the UART spi: ich: Don't require the PCH tpm: cr50: Drop unnecessary coral headers x86: Don't set up MTRRs if previously done x86: Update the MP constants to avoid conflicts x86: Do cache set-up by default when booting from coreboot x86: coreboot: Show the BIOS date x86: coral: Allow booting from coreboot x86: Add function comments to cb_sysinfo.h x86: coreboot: Use vendor in the Kconfig x86: coreboot: Document the memory map x86: cros: Check ROM exists before building vboot dtoc: Check that a parent is not missing doc: Update documentation for cros-2021.04 release arch/x86/cpu/coreboot/Kconfig | 2 +- arch/x86/cpu/i386/cpu.c | 2 +- arch/x86/dts/chromebook_coral.dts | 2 +- arch/x86/dts/chromebook_samus.dts | 2 +- arch/x86/include/asm/cb_sysinfo.h | 16 ++++++ arch/x86/include/asm/mp.h | 12 +++-- arch/x86/lib/init_helpers.c | 18 +++++-- board/coreboot/coreboot/Kconfig | 12 +++-- board/coreboot/coreboot/coreboot.c | 3 ++ board/google/chromebook_coral/coral.c | 28 ++++++++++ doc/board/coreboot/coreboot.rst | 21 ++++++++ doc/chromium/run_vboot.rst | 15 +++--- doc/device-tree-bindings/pci/x86-pci.txt | 7 ++- drivers/pci/pci-uclass.c | 39 ++++++++++++-- drivers/serial/serial_coreboot.c | 68 +++++++++++++++++++++--- drivers/spi/ich.c | 4 +- drivers/tpm/cr50_i2c.c | 2 - include/dt-bindings/pci/pci.h | 12 +++++ include/pci.h | 5 +- include/pci_ids.h | 1 + tools/dtoc/dtb_platdata.py | 9 ++++ tools/dtoc/test/dtoc_test_noparent.dts | 32 +++++++++++ tools/dtoc/test_dtoc.py | 10 ++++ 23 files changed, 278 insertions(+), 44 deletions(-) create mode 100644 include/dt-bindings/pci/pci.h create mode 100644 tools/dtoc/test/dtoc_test_noparent.dts -- 2.31.1.498.g6c1eba8ee3d-goog
