So, a problem is that we need to get at values after they've been pre-processed: /bin/sh: 1: printf: (SRAM_SCRATCH_SPACE_ADDR - CONFIG_SPL_TEXT_BASE): expected numeric value spl/u-boot-spl-dtb.bin exceeds file size limit: limit: 0 bytes actual: 124970 bytes excess: 124970 bytes ../scripts/Makefile.spl:266: recipe for target 'spl/u-boot-spl-dtb.bin' failed -- Tom
