SPL has a foot-print constraint, so fully switching a particular subsystem like SPI or SPI Flash to DM would increase the size of it.
Possible areas to look at are (assume SPL_DM supported)
- platdata
- implement board or platform specific spl device driver which
bypassed the actual framework ex: spl_spi_sunxi.c
Do we have any other solutions? or any arguments on above step 2?
SPL does not need to support DM until the size problem is solved.
I don't think the problem will ever be 'solved'. It is an ongoing battle.
But as it happens I've just sent a proposal for tiny-dm that I think will help.
Jagan, which board are you trying to convert? If you are trying to convert SPI flash, I think we need to remove the legacy code first.
If you want a board which boots from SPI NOR and has some 14k or so limit on SPL, any of the R-Car Gen2 boards fit the bill.
Thanks...do you have a link to one?
Also was there a 64-bit board that had to run 64-bit SPL? I think I remember you mentioning it.
