At present we have no standard way of passing information from SPL to U-Boot. Such information may be the size of DRAM banks or some information about the reset state of the machine,for example.
This series first adds a bloblist, which allows a list of 'blobs' to be created, each with a tag so that subsystems can store data and retrieve it later. Then it adds the SPL 'handoff' information, which uses bloblist. Various minor sandbox enhancements are provided to make this easier, or to support testing. Changes in v3: - Add comments to the log_ret() functions to indicate usage - Update log_msg_ret() to make use of the message and avoid a warning - Correct CONFIG_BLOBLIST_ADDR to have a default only for sandbox - Drop patch 'spl: Print a message if we are unable to load an image' Changes in v2: - Fix several typos - Add back a blank line, and put one in the new function too - Drop the wildcard in the .lds file as it is not needed Simon Glass (21): spl: Add support for logging in SPL and TPL Add core support for a bloblist to convey data from SPL spl: Set up the bloblist in SPL bloblist: Locate bloblist in U-Boot test: Add a simple test for bloblist Add bloblist documentation spl: Support hash, input, pch, pci, rtc, tpm in SPL spl: Add a define for SPL_TPL_PROMPT spl: Make SPL_DISABLE_BANNER_PRINT a positive option spl: Add a comment to spl_set_bd() sandbox: Add a memory map to the sandbox README test/py: Add a way to pass flags to sandbox sandbox: Add an option to display of-platdata in SPL sandbox: Drop the deprecated 'sb' command sandbox: Add a new 'sb' command sandbox: Allow puts() output before global_data is set up sandbox: Refactor code to create os_jump_to_file() sandbox: Use malloc() and free() from os layer sandbox: Filter arguments when starting U-Boot sandbox: Boot in U-Boot through the standard call spl: Add support for passing handoff info to U-Boot proper arch/Kconfig | 1 + arch/powerpc/include/asm/spl.h | 3 - arch/sandbox/cpu/eth-raw-os.c | 9 +- arch/sandbox/cpu/os.c | 115 +++++++++----- arch/sandbox/cpu/spl.c | 31 +++- arch/sandbox/cpu/start.c | 19 +++ arch/sandbox/cpu/u-boot-spl.lds | 2 +- arch/sandbox/include/asm/handoff.h | 18 +++ arch/sandbox/include/asm/state.h | 8 + board/sandbox/README.sandbox | 14 +- cmd/Makefile | 1 + cmd/host.c | 5 - cmd/sb.c | 65 ++++++++ common/Kconfig | 84 +++++++++- common/Makefile | 5 +- common/bloblist.c | 239 +++++++++++++++++++++++++++++ common/board_f.c | 49 ++++++ common/console.c | 7 + common/init/Makefile | 1 + common/init/handoff.c | 47 ++++++ common/spl/Kconfig | 95 +++++++++++- common/spl/spl.c | 135 ++++++++++++---- configs/sandbox_spl_defconfig | 1 + doc/README.bloblist | 82 ++++++++++ doc/README.trace | 2 +- drivers/Makefile | 11 +- include/asm-generic/global_data.h | 7 + include/bloblist.h | 195 +++++++++++++++++++++++ include/handoff.h | 36 +++++ include/log.h | 20 ++- include/spl.h | 41 +++++ include/test/suites.h | 1 + test/Makefile | 1 + test/bloblist.c | 187 ++++++++++++++++++++++ test/cmd_ut.c | 3 + test/dm/sf.c | 2 +- test/py/tests/test_fit.py | 12 +- test/py/tests/test_handoff.py | 14 ++ test/py/tests/test_ofplatdata.py | 31 +++- test/py/tests/test_vboot.py | 2 +- test/py/u_boot_console_base.py | 2 +- test/py/u_boot_console_sandbox.py | 18 +++ test/run | 2 +- 43 files changed, 1516 insertions(+), 107 deletions(-) create mode 100644 arch/sandbox/include/asm/handoff.h create mode 100644 cmd/sb.c create mode 100644 common/bloblist.c create mode 100644 common/init/handoff.c create mode 100644 doc/README.bloblist create mode 100644 include/bloblist.h create mode 100644 include/handoff.h create mode 100644 test/bloblist.c create mode 100644 test/py/tests/test_handoff.py -- 2.19.1.1215.g8438c0b245-goog _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
