v3.19.8-ckt17 -stable review patch. If anyone has any objections, please let me know. ---8<------------------------------------------------------------ From: Timothy Pearson <tpearson@xxxxxxxxxxxxxxxxxxxxxxxx> commit 2d02b8bdba322b527c5f5168ce1ca10c2d982a78 upstream. During DRAM initialization on certain ASpeed devices, an incorrect bit (bit 10) was checked in the "SDRAM Bus Width Status" register to determine DRAM width. Query bit 6 instead in accordance with the Aspeed AST2050 datasheet v1.05.
