There is a pre-defined border for build-time checks (at least on ARM -> CONFIG_SPL_MAX_SIZE) and some tools to investigate runtime behavior (*.su files -> read README.SPL 'estimating stack usage'). > Did anyone tried to do this before and could share experiences? I pulled the software implementation of BCH in SPL to have second NAND sector secured by BCH8 on OMAP3 devices (which have no ELM). It worked on board tricorder and devkit8000 but I had to increase the CONFIG_SPL_MAX_SIZE (AFAIR).
