Hi<br>
I am using linux-2.6.26.8 kernel. In drivers/mtd/nand/Kconfig,
MTD_NAND_FSL_UPM depends on MTD_NAND &amp;&amp; OF_GPIO &amp;&amp;
(PPC_83xx || PPC_85xx). But I didnt find any way to select OF_GPIO
option in &quot;make menuconfig&quot;. So I removed it from Kconfig file and got
MTD_NAND_FSL_UPM in menuconfig. I selected it and did &quot;make uImage&quot;.
This is giving few errors:<br>
<br>

I am suspection that some gpio lib is missing. So any patch is there to this problem??<br>
