I'm wondering if we could use blobs to provide information from SPL/TPL regarding "bootcount". It seems like a better approach than the one which we do use now (as a set of magic include functions for u-boot proper and SPL/TPL). > > Various minor sandbox enhancements are provided to make this easier, > or to support testing. > > > Simon Glass (22): > log: Correct definition of log_msg_ret() > 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() > spl: Print a message if we are unable to load an image > 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: 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 | > 47 ++++++ common/console.c | 7 + > common/init/Makefile | 1 + > common/init/handoff.c | 47 ++++++ > common/spl/Kconfig | 95 +++++++++++- > common/spl/spl.c | 142 +++++++++++++---- > configs/sandbox_spl_defconfig | 1 + > doc/README.bloblist | 82 ++++++++++ > drivers/Makefile | 11 +- > include/asm-generic/global_data.h | 7 + > include/bloblist.h | 194 +++++++++++++++++++++++ > include/handoff.h | 36 +++++ > include/log.h | 10 +- > include/spl.h | 41 +++++ > include/test/suites.h | 1 + > test/Makefile | 1 + > test/bloblist.c | 187 ++++++++++++++++++++++ > test/cmd_ut.c | 3 + > test/py/tests/test_handoff.py | 14 ++ > test/py/tests/test_ofplatdata.py | 31 +++- > test/py/u_boot_console_base.py | 2 +- > test/py/u_boot_console_sandbox.py | 18 ++- > test/run | 2 +- > 39 files changed, 1497 insertions(+), 102 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 > Best regards, Lukasz Majewski -- DENX Software Engineering GmbH, Managing Director: Wolfgang Denk HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany Phone: (+49)-8142-66989-10 Fax: (+49)-8142-66989-80 Email: w...@denx.de
