* driver/ddr/fsl: Add workaround for erratum A-010165Shengzhou Liu2016-05-18-1/+9
| | | | | | | | | During DDR-2133 operation, the transmit data eye margins determined during the memory controller initialization may be sub-optimal, set DEBUG_29[12] and DEBUG_29[13:16] = 4'b0100 before MEM_EN is set.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to the MPC8555/MPC8541 reference manual the SS_EN (source synchronous enable) bit in the DDR_SDRAM_CLK_CNLT register must be set during initialization. >From section 9.4.1.8 of that manual: Source synchronous enable. This bit field must be set during initialization. See Section 9.6.1, "DDR SDRAM Initialization Sequence," details. 0 - Reserved 1 - The address and command are sent to the DDR SDRAMs source synchronously. In addition, Freescale application note AN2805 is also very clear that this bit must be set. This patch reverts a change introduced by commit 457caecdbca3df21a93abff19eab12dbc61b7897. Testing Done: Compiled targets CONFIG_TARGET_MPC8555CDS and CONFIG_TARGET_MPC8541CDS and inspected the generated assembly code to verify the SS_EN bit was being set. There is one extra instruction emitted: fff9b774: 65 29 80 00 oris r9,r9,32768 Compiled the CONFIG_TARGET_MPC8548CDS target and verified that no additional instructions were emitted related to this patch.
