So I'm asking for advice (and I'd definitely > like to not selectively prepend "#define DEBUG" all over the place) Figured hard-hacking 1 into the #define debug() in log.h does what I wanted. Probably not exactly elegant, but at least it lets me see the messages: U-Boot SPL 2019.01-rc2 (Dec 23 2018 - 00:26:45 +0300) CPU: 912000000Hz, AXI/AHB/APB: 3/2/2 DRAM: 1024 MiB >>SPL: board_init_r() Trying to boot from NAND spl: nand - using hw ecc mkimage signature not found - ih_magic = 0 Jumping to U-Boot SPL malloc() used 0x0 bytes (0 KB) loaded - jumping to U-Boot... image entry point: 0x4a000000 It looks like SPL loads 0x0 bytes of u-boot and runs it! Hmm, interesting. Its a good start already. Now just need to insert some more debugging messages... Thank you!
