2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini1-2/+1
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>

Commit 34e026f9 added one extra bit to wr_lat for timing_cfg_2, but with wrong bit position. It is bit 13 in big-endian, or left shift 18 from LSB. This error hasn't had any impact because we don't have fast enough DDR4 using the extra bit so far. Signed-off-by: York Sun <york.sun@nxp.com>

2015-04-20MPC8541/MPC8555: Enable SS_EN in DDR_SDRAM_CLK_CNLT registerCurt Brune1-1/+9
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.

2014-09-08driver/ddr/fsl: Add support of overriding chip select write levelingYork Sun1-0/+3
JEDEC spec allows DRAM vendors to use prime DQ for write leveling. This is not an issue unless some DQ pins are not connected.
