The exposed string representation is encoded in a manufacturer-specific manner, hence for use in scripting, soc_uid_bin should be accessible in a generic representation. > For example on i.MX8MP the byte order was reversed in comparing > the return value of barebox_get_soc_uid_bin and $global.soc_uid. This was discussed with regard to i.MX8MP, where the byte order of $global.soc_uid and linux' /sys/devices/soc0/serial_number is reversed compared to barebox_get_soc_uid_bin. Regardless of whether the current value of barebox_get_soc_uid_bin is correct, barebox_get_soc_uid_bin should be used for scripting. > Signed-off-by: Fabian Pflug > --- > Fabian Pflug (2): > common: misc: add soc_uid_bin to globalvar > i.MX: HAB: update text for HABV4_CSF_UNLOCK_UID > > arch/arm/mach-imx/Kconfig | 11 +++-------- > common/misc.c | 8 ++++++-- > 2 files changed, 9 insertions(+), 10 deletions(-) > --- > base-commit: 1d386a53086d28a0c4eda138ae9408a418b97b7e > change-id: 20260330-v2026-03-0-topic-soc_bin_id-d12a84d7b1b5 > > Best regards, -- Pengutronix e.K. | Jonas Rebmann | Steuerwalder Str. 21 | http://www.pengutronix.de/ | 31137 Hildesheim, Germany | Phone: +49-5121-206917-0 | Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917-9 |
