Hi,
What do people think about requiring SPL_DM for new boards? Would that cause any problems?
There is not much use of of-platdata (compiling the DT into C to save space) - is that because it doesn't work for people?
I am particularly keen to drop the old block interface from SPL. It seems to me that boards that can use that might have enough space to enable SPL_DM and SPL_DM_BLK? What do people think?
I don't think this works. The problem is we aren't seeing new SoCs that have a large initial amount of memory but rather many continuing to have 32KiB or similar tiny sizes. So, I'd rather continue to go with saying it's optional, but that we won't introduce new SPL functionality that can be DM or not DM, but only new functionality that needs SPL_DM and if platforms want it, but have limited memory, we need to go TPL->SPL in that case.
OK I see.
What do you think of a migration method for boards which don't use SPL_DM, so they migrate to TPL? Would that cause a lot of problems?
I'm not sure what it gains us. Maybe the first step here is to see what the list of non-DM_SPL platforms / SoCs are?
