You did not move qe_reset() inside qe_init() as you recommended.:)
For NAND boot case, the microcode needs to be read from nand flash via
nand_read first, so you might add some more code like:
+void cpu_late_init_r(void)
+{
+#ifdef CONFIG_QE
+#ifdef CONFIG_SYS_QE_FW_IN_NAND
+ int ret;
+ size_t fw_length = CONFIG_SYS_QE_FW_LENGTH;
+ /* load QE firmware from NAND flash to DDR first */
+ ret = nand_read(&nand_info[0],(loff_t)CONFIG_SYS_QE_FW_IN_NAND,
+ &fw_length, (u_char *)CONFIG_SYS_QE_FW_ADDR);
+ if (ret && ret == -EUCLEAN) {
+ printf ("NAND read for QE firmware at offset %x failed %
d\n",
+ CONFIG_SYS_QE_FW_IN_NAND, ret);
+ }
+#endif
+ uint qe_base = CONFIG_SYS_IMMR + 0x00080000; /* QE immr base */
+ qe_init(qe_base);
+ qe_reset();
+#endif
+}
