nvidia-tegra-modules.git/drivers/platform/tegra/bcp.c, branch rtss22-ae NVIDIA's kernel modules to support tegra chips (used in Jetson boards) tegra_bootloader_debug: BCP data from bootloader 2018-07-15T04:44:46+00:00 Taborowski Lukasz lukasz.taborowski@harman.com 2018-07-11T09:51:21+00:00 a15e919aa0263cdea28cdc41fa49d01d5743d895 Information about BCP location is passed in bootargs. Kernel maps BCP location as memory reserved block to prevent from overwriting it. If kernel receives boot_cfg_dataptr then new module bcp is loaded. This means that BCP data is available at /sys/kernel/boot_cfg location. Additionally, extended the tegra_bootloader_debug module to BCP area. After the module is loaded, debugfs exposes new file the boot_cfg.
