reduce firmware image size #1
Description
linux-5.10.83-armv7-lpae-x58.defconfig is based https://github.com/RobertCNelson/armv7-lpae-multiplatform/tree/5.10.83-armv7-lpae-x58 linux configuration.
- The configuration is not only for stm32mp157c_odyssey, but also for other boards.
- It is not specific to Nerves, it also contains unnecessary configs.
So, if we can remove them, we should be able to reduce the firmware size.
