If the bootfailure count +is more than 3, the u-boot will abort the booting to BMC. This fix will +remove the bootfailure count incrementing if PFR is provisioned as PFR +CPLD will boot a recovery image anyway if the booting process is not +working as expected and stopping in u-boot is not necessary. + +Tested: +triggered kernel panic 4 times and confirmed that boot process +is not aborted at u-boot in PFR provisioned mode. + +Signed-off-by: AKSHAY RAVEENDRAN K <akshay.raveendran.k@intel.com> +--- + board/aspeed/ast2600_intel/intel.c | 3 ++- + 1 file changed, 2 insertions(+), 1 deletion(-) + +diff --git a/board/aspeed/ast2600_intel/intel.c b/board/aspeed/ast2600_intel/intel.c +index c0d82bfb4b..5a54051ac7 100644 +--- a/board/aspeed/ast2600_intel/intel.c ++++ b/board/aspeed/ast2600_intel/intel.c +@@ -13,6 +13,7 @@ + #define SYS_PWR_RESET_FLAG BIT(0) /* from scu_info.c */ + #define WATCHDOG_RESET_BIT BIT(20) + #define BOOT_FAILURE_LIMIT 3 ++#define EXTRST_RESET_BIT BIT(1) + + #define SCU_014 0x014 /* Silicon Revision ID */ + #define REV_ID_AST2600A0 0x05000303 /* AST2600 A0 */ +@@ -703,7 +704,7 @@ int board_late_init(void) + + boot_failures = get_boot_failures(); + +- if (gd->reset_reason & WATCHDOG_RESET_BIT) ++ if ((gd->reset_reason & WATCHDOG_RESET_BIT) && !(gd->reset_reason & EXTRST_RESET_BIT)) + set_boot_failures(boot_failures + 1); + else + set_boot_failures(0); +-- +2.17.1 + |
