Like adding the policy name to the commandline and configuring pinmux based on the selected policy. If this series is to be applied after Ahamad's bootm change series, then the block to change the commandline has to be moved up to roughly line 720 into the function bootm_boot_prep, where all the other bootm_data->provide_*** checks are, so that the previous context remains the same. Signed-off-by: Fabian Pflug --- Changes in v4: - removed the global variable active_policy and replaced with a getter function - add sanity check for is_allow parameter - add new notifier chain to security_policy on change without checking policies is_allowed - rewrote the pinctrl to make use of new notify chain - changed pinctrl to use barebox,policy-- to replace pinctrl for instead of replacing 'default' - Link to v3: https://lore.barebox.org/barebox/20260318-v2026-02-0-topic-sconfig_console-v3-0-e26055294723@pengutronix.de Changes in v3: - replaced while loop with of_tree_for_each_node_from - removed unsused variable definition in base.c - Link to v2: https://lore.barebox.org/barebox/20260316-v2026-02-0-topic-sconfig_console-v2-0-1eee8c762beb@pengutronix.de Changes in v2: - Add of_property_write_string_array function - Add selftest for of_property_write_string_array - Add exra-check for active-policy - Use "linux.bootargs.dyn.policy" instead of version without dyn - Iterate over device-nodes instead of recurse through tree - Link to v1: https://lore.barebox.org/barebox/20260312-v2026-02-0-topic-sconfig_console-v1-0-4c3fccafab1e@pengutronix.de --- Fabian Pflug (7): of: add of_property_write_string_array() security: policy: sanity check parameters security: policy: remove global active_policy var security: policy: add notifier chain for name change common: bootm: add policy to commandline drivers: pinctrl: configure pinctrl based on policy name security: kernel_pinctrl: fixup pinctrl in kernel dts commands/sconfig.c | 9 +++++- common/bootm.c | 24 ++++++++++++++ drivers/of/base.c | 43 +++++++++++++++++++++++++ drivers/pinctrl/pinctrl.c | 73 +++++++++++++++++++++++++++++++++++++++++-- include/bootm.h | 5 +++ include/of.h | 3 ++ include/security/config.h | 1 + include/security/policy.h | 3 +- security/Kconfig.policy | 15 ++++++++- security/Makefile | 1 + security/kernel_pinctrl.c | 65 ++++++++++++++++++++++++++++++++++++++ security/policy.c | 21 +++++++++---- test/self/of_manipulation.c | 14 ++++++++- test/self/of_manipulation.dts | 5 +++ 14 files changed, 269 insertions(+), 13 deletions(-) --- base-commit: 1d386a53086d28a0c4eda138ae9408a418b97b7e change-id: 20260311-v2026-02-0-topic-sconfig_console-194842a14e1d Best regards, -- Fabian Pflug
