Add CONFIG_QCOM_SNAGBOOT_MODE to enable snagboot mode on Qualcomm platforms. This config automatically selects the required dependencies for Snagboot mode.
Add QCOM_BOOT0_SNAGBOOT_MODE as a hidden boot0.h config, selected automatically by QCOM_SNAGBOOT_MODE. This boot0.h config is for disabling MMU at the start of U-Boot execution. Signed-off-by: Balaji Selvanathan <[email protected]> --- Changes in v10: - Depend on ENV_IS_DEFAULT instead of selecting ENV_IS_NOWHERE and depending on !ENV_IS_IN_SCSI - Drop depends on COUNTER_FREQUENCY != 0 - Drop depends on TEXT_BASE != 0x0 - Drop depends on !PSCI_RESET and !SAVE_PREV_BL_INITRAMFS_START_ADDR Changes in v9: - Remove depends on !IOMMU from QCOM_SNAGBOOT_MODE Changes in v7: - No changes Changes in v5: - Made QCOM_BOOT0_SNAGBOOT_MODE dependent on QCOM_SNAGBOOT_MODE so it is not exposed to users - Add dependencies for QCOM_SNAGBOOT_MODE explicitly as "depends" Changes in v4: - Renamed QCOM_SNAGBOOT_SUPPORT to QCOM_SNAGBOOT_MODE - Added QCOM_BOOT0_SNAGBOOT_MODE for boot0.h which gets selected by QCOM_SNAGBOOT_MODE - Document the platform-specific requirements and configs that must be disabled in snagboot mode.
