[U-Boot] [PATCH 3/4] OneNAND: Introduce CONFIG_SYS_IPL_LOAD_ADDR

[Marek Vasut]

This allows to specify where the OneNAND IPL should load the U-Boot binary. The
purpose of CONFIG_SYS_LOAD_ADDR is different I believe.

On PXA, this is needed with OneNAND memories that expose only first 1kb of data,
which is insufficient for SDRAM init. U-Boot can then be copied into SRAM.
