I am trying to configure NAND to be compiled in the kernel for an AM335x processor, but am encountering an issue. I am using the ti-sdk-am335x-evm-05.04.-1.00 SDK . The compile error below occurs after I have enabled Device Drivers > Memory Technology Device (MTD) support > NAND Device Support > NAND Flash device on OMAP2, OMAP3 and OMAP4 as a module using make menuconfig.

I have grep'd for "omap3_evm_nand_partitions" recursively on the entire SDK and it only finds it being used in two instances in board-support/linux-3.2-psp04.06.00.07.sdk/arch/arm/mach-omap2/board-omap3evm.c, but no definition in any file. Are there missing sources in the SDK that I'm unaware of? Is there something else I need to enable in the kernel config?
