We should add a partitioning layer on top of the current interface.
And even better solution would be to introduce a common flash interface for NOR, NAND, SPI, etc. flash and add a partitioning layer on top of that.
rather than reinvent the wheel, just support redboot partitioning scheme. but yeah, i dont think it makes much sense to add partitioning support to each flash layer and turn around and unify it all. take the common layer approach first.
I have my own patches for the memory commands to enable most of this but adding that to the cmd_mem driver was not accepted.
Yes, as you probably know, I for one think memory mapping of serial devices is a bad idea.
agreed here ... especially on systems that cant ...
Also, caching sounds like something which comes dangerously close to crossing the line between "boot loader" and "operating system". I don't think it fits well into the current u-boot architecture.
