2019-04-17ddr: altera: Stratix10: Add ECC memory scrubbingLey Foon Tan
Scrub memory content if ECC is enabled and it is not from warm reset boot. Enable icache and dcache before scrub memory and use "DC ZVA" instruction to clear memory to zeros. This instruction writes a cache line at a time and it can prevent false ECC error trigger if write cache line partially. Signed-off-by: Ley Foon Tan <ley.foon.tan@intel.com>
2019-04-17ddr: altera: Stratix10: Add multi-banks DRAM size checkLey Foon Tan
Stratix 10 maps dram from 0 to 128GB. There is a 2GB hole in the memory for peripherals and other IO from 2GB to 4GB. However the dram controller ignores upper address bits for smaller dram configurations. Example: a 4GB dram maps to multiple locations, every 4GB on the address.

2019-04-17arm: socfpga: move gen5 SDR driver to DMSimon Goldschmidt
To clean up reset handling for socfpga gen5, port the DDR driver to DM using UCLASS_RAM and implement proper reset handling. This gets us rid of one ad-hoc call to socfpga_per_reset(). The gen5 driver is implemented in 2 distinct files. One of it (containing the calibration training) is not touched much and is kept at using hard coded addresses since the code grows even more otherwise. SPL is changed from calling hard into the DDR driver code to just probing UCLASS_RESET and UCLASS_RAM. It is happy after finding a RAM driver after that.

2019-04-12arm: mvebu: Add Marvell's integrated CPUsChris Packham
Marvell's switch chips with integrated CPUs (collectively referred to as MSYS) share common ancestry with the Armada SoCs. Some of the IP blocks (e.g. xor) are located at different addresses and DFX server exists as a separate target on the MBUS (on Armada-38x it's just part of the core complex registers).

2019-03-09ddr: socfpga: Clean up ddr_setup()Marek Vasut
Replace the current rather convoluted code using ad-hoc polling mechanism with a more straightforward code. Use wait_for_bit_le32() to poll the DDRCALSTAT register instead of local reimplementation. It makes no sense to pull for 5 seconds before giving up and trying to restart the EMIF, so instead wait 500 mSec for the calibration to complete and if this fails, restart the EMIF and try again. Perform this 32 times instead of 3 times as the original code did.

2019-03-09ddr: socfpga: Clean up EMIF resetMarek Vasut
The EMIF reset code can well use wait_for_bit_le32() instead of all that convoluted polling code. Reduce the timeout from 100 seconds to 1 second, since if the EMIF fails to reset itself in 1 second, it's unlikely longer wait would help. Make sure to clear the EMIF reset request even if the SEQ2CORE_INT_RESP_BIT isn't asserted.

2018-07-12ddr: altera: Add ECC DRAM scrubbing support for Arria10Marek Vasut
The SDRAM must first be rewritten by zeroes if ECC is used to initialize the ECC metadata. Make the CPU overwrite the DRAM with zeroes in such a case. This scrubbing implementation turns the caches on temporarily, then overwrites the whole RAM with zeroes, flushes the caches and turns them off again. This provides satisfactory performance.

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>
