2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
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>
2015-08-08ddr: altera: sequencer: Zap SEQ_T(INIT|RESET)_CNTR._VALMarek Vasut
This is another macro used to obfuscate the real code. The T(INIT|RESET)_CNTR._VAL is always defined, so this indirection is unnecessary. Get rid of this. Signed-off-by: Marek Vasut <marex@denx.de> Acked-by: Dinh Nguyen <dinguyen@opensource.altera.com>
2015-08-08ddr: altera: sequencer: Zap VFIFO_SIZEMarek Vasut
Just use READ_VALID_FIFO_SIZE directly, no need for this macro obfuscation. Signed-off-by: Marek Vasut <marex@denx.de> Acked-by: Dinh Nguyen <dinguyen@opensource.altera.com>
2015-08-08ddr: altera: sequencer: Pluck out RW_MGR_* macros from codeMarek Vasut
Actually convert the sequencer code to use socfpga_sdram_rw_mgr_config instead of the RW_MGR_* macros. This is just an sed exercise here, no manual coding needed. Signed-off-by: Marek Vasut <marex@denx.de> Acked-by: Dinh Nguyen <dinguyen@opensource.altera.com>
2015-08-08ddr: altera: sequencer: Zap bogus redefinition of RW_MGR_MEM_NUMBER_OF_RANKSMarek Vasut
This is defined in the QTS-generated headers, so it must not be re-defined in sequencer.h . Signed-off-by: Marek Vasut <marex@denx.de> Acked-by: Dinh Nguyen <dinguyen@opensource.altera.com>
2015-08-08ddr: altera: sequencer: Zap unused params and macrosMarek Vasut
These parameters are not used in the code, zap them and the macros which are used by them as well. Signed-off-by: Marek Vasut <marex@denx.de> Acked-by: Dinh Nguyen <dinguyen@opensource.altera.com>
2015-08-08ddr: altera: Clean up mem_config()Marek Vasut
Clean mem_config() function. First, reorder the math done in the function such that WLAT and RLAT computation is together. Then, scrap contradictory comments which do not match the result of the math at all. Next, extract the mem_precharge_and_activate() call from the end of the function as it is completely unrelated here. Finally, rename the function to mem_init_latency().

2015-08-08ddr: altera: Stop using SDR_CTRLGRP_ADDRESS directlyMarek Vasut
Use the proper structure which describes these registers, especially since this is already in place. Signed-off-by: Marek Vasut <marex@denx.de>
2015-08-08ddr: altera: Wrap SOCFPGA_SDR_ADDRESS into SDR_PHYGRP.*ADDRESSMarek Vasut
Just trim down the constant SOCFPGA_SDR_ADDRESS + SDR_PHYGRP.*ADDRESS in the code. Signed-off-by: Marek Vasut <marex@denx.de>
2015-08-08ddr: altera: Pluck out remaining sdr_get_addr() callsMarek Vasut
Remove the remaining invocations of sdr_get_addr() and the function itself. This makes the code a bit less cryptic. Signed-off-by: Marek Vasut <marex@denx.de>
2015-08-08driver/ddr/altera: Add the sdram calibration portionDinh Nguyen
This patch adds the DDR calibration portion of the Altera SDRAM driver. Signed-off-by: Dinh Nguyen <dinguyen@opensource.altera.com>
