We are in the process of adding our internal U-Boot changes to the latest public U-Boot. One "problem" we face is that we have multiple SoCs each with a (slightly) different MIPS core variant. Adding them all under cpu/mips and #ifdef-ing start.S does not seem appealing. Our preference is to have a separate cpu directory for each SoC, more or less as is done for the MPCs. Any ideas, suggestions? Thanks in advance.
There is no general answer so such a vague question. If there are inded only slight differences, separate directories would probably contain mostly duplicated code, which is unacceptable. Then rather have a few (I really mean *few*) #ifdef's, or call some private init function which can be implemented in a board / SoC specific way.
Best regards,
