Currently the SPL binary is 67 kB, which leaves only 1 kB of free internal RAM space.
The following options can be safely removed to save some precious SPL space:
- CONFIG_SPL_FS_EXT4: u-boot-dtb.img is stored in raw sector via dd command (at offset 69 kB) - CONFIG_SPL_I2C_SUPPORT: I2C is not used during SPL - CONFIG_SPL_OS_BOOT: no need to make Falcon mode supported by default
After this change the SPL binary size gets down to 51 kB.
