Reduce the SPL size by the same amount so that it can boot again. Further SPL reduction work is needed, such as removing driver model support in SPL. Just to provide a comparison: NXP U-Boot tree has a SPL binary size of 64kB versus 96KB in U-Boot mainline. Signed-off-by: Fabio Estevam --- Hi, I plan to reduce SPL size even further by removing SPL_DM=y, but this needs more time to accomplish, so I prefer to give a small SPL reduction at this time, just to allow the board to boot again. Also, will try to come up with a SPL size detection in build time, as it is hard to debug such issues in run-time. configs/imx8mp_evk_defconfig | 4 ---- 1 file changed, 4 deletions(-) diff --git a/configs/imx8mp_evk_defconfig b/configs/imx8mp_evk_defconfig index 44b2935f69..00f4ccbe0d 100644 --- a/configs/imx8mp_evk_defconfig +++ b/configs/imx8mp_evk_defconfig @@ -33,7 +33,6 @@ CONFIG_SPL_BOOTROM_SUPPORT=y CONFIG_SPL_SEPARATE_BSS=y CONFIG_SPL_I2C_SUPPORT=y CONFIG_SPL_POWER_SUPPORT=y -CONFIG_SPL_WATCHDOG_SUPPORT=y CONFIG_HUSH_PARSER=y CONFIG_SYS_PROMPT="u-boot=> " # CONFIG_CMD_EXPORTENV is not set @@ -79,8 +78,5 @@ CONFIG_DM_REGULATOR_FIXED=y CONFIG_DM_REGULATOR_GPIO=y CONFIG_MXC_UART=y CONFIG_SYSRESET=y -CONFIG_SPL_SYSRESET=y CONFIG_SYSRESET_PSCI=y -CONFIG_SYSRESET_WATCHDOG=y # CONFIG_WATCHDOG is not set -CONFIG_IMX_WATCHDOG=y
