Hi Boris,

The only implementer of this function has been patched to use CONFIG_MTD{IDS,PARTS}_DEFAULT instead. Let's get rid of this function and the associated CONFIG_SYS_MTDPARTS_RUNTIME option.
the only implementer of this fuction did so for a good reason. What is a motivation to remove it?
The requirement is to be able to use single u-boot binary on all igep2 boards ever produced. These comes with various NAND and OneNAND chips and I was not able to come with single static partition configuration to support them all. Hence runtime detection. That code could be used on all OMAP3 boards as BootROM reads up to first four sectors searching for SPL (MLO).
Thank you, ladis
