Subject: [U-Boot] [PATCH v4 9/9] arm: ls102xa: Add NAND boot support for
 LS1021AQDS board

Refer to "Table 5-1. LS1 memory map" in "LS1 SoC Architecture Specification". It shows that:
Start Address: 0x200000000  Size: 16MB   DCSR

Or, see the dcsr node in arch/arm/boot/dts/ls1021a.dtsi in Linux.

Thanks,
Chenhui

This line is conflict with this patch http://patchwork.ozlabs.org/patch/402218/.
Which one is correct?
