Signed-off-by: Russ Weight Acked-by: Lee Jones --- v6: - No change v5: - Renamed USER_FLASH_COUNT to STAGING_FLASH_COUNT v4: - No change v3: - Changed "MAX10 BMC Secure Engine driver" to "MAX10 BMC Secure Update driver" - Removed wrapper functions (m10bmc_raw_*, m10bmc_sys_*). The underlying functions will be called directly. v2: - These functions and macros were previously distributed among the patches that needed them. They are now grouped together in a single patch containing changes to the Intel MAX10 BMC driver. - Added DRBL_ prefix to some definitions - Some address definitions were moved here from the .c files that use them. --- include/linux/mfd/intel-m10-bmc.h | 85 +++++++++++++++++++++++++++++++ 1 file changed, 85 insertions(+) diff --git a/include/linux/mfd/intel-m10-bmc.h b/include/linux/mfd/intel-m10-bmc.h index c8ef2f1654a4..ab8d78b92df9 100644 --- a/include/linux/mfd/intel-m10-bmc.h +++ b/include/linux/mfd/intel-m10-bmc.h @@ -13,6 +13,9 @@ #define M10BMC_SYS_BASE 0x300800 #define M10BMC_MEM_END 0x200000fc +#define M10BMC_STAGING_BASE 0x18000000 +#define M10BMC_STAGING_SIZE 0x3800000 + /* Register offset of system registers */ #define NIOS2_FW_VERSION 0x0 #define M10BMC_TEST_REG 0x3c @@ -21,6 +24,88 @@ #define M10BMC_VER_PCB_INFO_MSK GENMASK(31, 24) #define M10BMC_VER_LEGACY_INVALID 0xffffffff +/* Secure update doorbell register, in system register region */ +#define M10BMC_DOORBELL 0x400 + +/* Authorization Result register, in system register region */ +#define M10BMC_AUTH_RESULT 0x404 + +/* Doorbell register fields */ +#define DRBL_RSU_REQUEST BIT(0) +#define DRBL_RSU_PROGRESS GENMASK(7, 4) +#define DRBL_HOST_STATUS GENMASK(11, 8) +#define DRBL_RSU_STATUS GENMASK(23, 16) +#define DRBL_PKVL_EEPROM_LOAD_SEC BIT(24) +#define DRBL_PKVL1_POLL_EN BIT(25) +#define DRBL_PKVL2_POLL_EN BIT(26) +#define DRBL_CONFIG_SEL BIT(28) +#define DRBL_REBOOT_REQ BIT(29) +#define DRBL_REBOOT_DISABLED BIT(30) + +/* Progress states */ +#define RSU_PROG_IDLE 0x0 +#define RSU_PROG_PREPARE 0x1 +#define RSU_PROG_READY 0x3 +#define RSU_PROG_AUTHENTICATING 0x4 +#define RSU_PROG_COPYING 0x5 +#define RSU_PROG_UPDATE_CANCEL 0x6 +#define RSU_PROG_PROGRAM_KEY_HASH 0x7 +#define RSU_PROG_RSU_DONE 0x8 +#define RSU_PROG_PKVL_PROM_DONE 0x9 + +/* Device and error states */ +#define RSU_STAT_NORMAL 0x0 +#define RSU_STAT_TIMEOUT 0x1 +#define RSU_STAT_AUTH_FAIL 0x2 +#define RSU_STAT_COPY_FAIL 0x3 +#define RSU_STAT_FATAL 0x4 +#define RSU_STAT_PKVL_REJECT 0x5 +#define RSU_STAT_NON_INC 0x6 +#define RSU_STAT_ERASE_FAIL 0x7 +#define RSU_STAT_WEAROUT 0x8 +#define RSU_STAT_NIOS_OK 0x80 +#define RSU_STAT_USER_OK 0x81 +#define RSU_STAT_FACTORY_OK 0x82 +#define RSU_STAT_USER_FAIL 0x83 +#define RSU_STAT_FACTORY_FAIL 0x84 +#define RSU_STAT_NIOS_FLASH_ERR 0x85 +#define RSU_STAT_FPGA_FLASH_ERR 0x86 + +#define HOST_STATUS_IDLE 0x0 +#define HOST_STATUS_WRITE_DONE 0x1 +#define HOST_STATUS_ABORT_RSU 0x2 + +#define rsu_prog(doorbell) FIELD_GET(DRBL_RSU_PROGRESS, doorbell) +#define rsu_stat(doorbell) FIELD_GET(DRBL_RSU_STATUS, doorbell) + +/* interval 100ms and timeout 5s */ +#define NIOS_HANDSHAKE_INTERVAL_US (100 * 1000) +#define NIOS_HANDSHAKE_TIMEOUT_US (5 * 1000 * 1000) + +/* RSU PREP Timeout (2 minutes) to erase flash staging area */ +#define RSU_PREP_INTERVAL_MS 100 +#define RSU_PREP_TIMEOUT_MS (2 * 60 * 1000) + +/* RSU Complete Timeout (40 minutes) for full flash update */ +#define RSU_COMPLETE_INTERVAL_MS 1000 +#define RSU_COMPLETE_TIMEOUT_MS (40 * 60 * 1000) + +/* Addresses for security related data in FLASH */ +#define BMC_REH_ADDR 0x17ffc004 +#define BMC_PROG_ADDR 0x17ffc000 +#define BMC_PROG_MAGIC 0x5746 + +#define SR_REH_ADDR 0x17ffd004 +#define SR_PROG_ADDR 0x17ffd000 +#define SR_PROG_MAGIC 0x5253 + +#define PR_REH_ADDR 0x17ffe004 +#define PR_PROG_ADDR 0x17ffe000 +#define PR_PROG_MAGIC 0x5250 + +/* Address of 4KB inverted bit vector containing staging area FLASH count */ +#define STAGING_FLASH_COUNT 0x17ffb000 + /** * struct intel_m10bmc - Intel MAX 10 BMC parent driver data structure * @dev: this device
