Do you recommend using SPL_SEPARATE_BSS on our platform? After power on, the sc598 has 2 MB of SRAM available starting at 0x20000000 which we treat as just a single block of memory to use for all of SPL operation, so we don't have any requirement to do something like a bare bones DDR initialization before using it as our main memory for SPL, so it didn't seem necessary to enable. The boot ROM has some guidelines on where it will place its stack, so we restrict SPL to the first 192 KB currently but this can easily be expanded. I'm not sure if I should admit to it, but some decisions on Kconfigs were made 4 years ago as an arbitrary choice during our initial bringup and then were not reviewed because things were working. Either way, works for me on the sc598 + ezkit. There's no reason for it to fail on the ezlite in that case either. Tested-by: Greg Malysa <[email protected]> Thanks, Greg
