2020-04-14arm: mvebu: drivers/ddr: remove redundant assignmentHeinrich Schuchardt
The value of local variable ecc is immediately overwritten. So we can remove the first assignment. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de> Reviewed-by: Stefan Roese <sr@denx.de>
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).

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>

2016-01-14arm: mvebu: Make ECC support configurable on Armada XPStefan Roese
Currently, ECC support is enabled for all Armada XP boards. So the DDR3 driver tries to configure the controller with ECC support, even on boards without ECC. This patch makes this ECC optional which now can be configured on a board-per-board basis.

2015-08-17arm: mvebu: Add complete SDRAM ECC scrubbingStefan Roese
This patch introduces the SDRAM scrubbing for ECC enabled board to fill/initialize the ECC bytes. This is done via the XOR engine to speed up the process. The scrubbing is a 2-stage process: 1) SPL scrubs the area 0 - 0x100.0000 (16MiB) for the main U-Boot 2) U-Boot scrubs the remaining SDRAM area(s) Signed-off-by: Stefan Roese <sr@denx.de> Cc: Luka Perkov <luka.perkov@sartura.hr>
2015-08-17arm: mvebu: sdram: Enable ECC support on Armada XPStefan Roese
This is tested on the DB-MV784MP-GP eval board. To really enable ECC support on this board the I2C EEPROM needs to get changed. As it saves the enabling of ECC support internally. For this the following commands can be used to enable ECC support on this board: Its recommended for first save (print) the value(s) in this EEPROM address: => i2c md 4e 0.1 2 0000: 05 00 .. To enable ECC support you need to set bit 1 in the 2nd byte: Marvell>> i2c mw 4e 1.1 02 Marvell>> i2c md 4e 0.1 2 0000: 05 02 .. To disable ECC support again, please use this command: Marvell>> i2c mw 4e 1.1 00 Marvell>> i2c md 4e 0.1 2 0000: 05 00 .. On other AXP boards, simply plugging an ECC DIMM should be enough to enable ECC support. Signed-off-by: Stefan Roese <sr@denx.de> Cc: Luka Perkov <luka.perkov@sartura.hr>
2015-07-23arm: mvebu: drivers/ddr: Move Armada XP DDR init code into new directoryStefan Roese
With the upcoming addition of the Armada 38x DDR support, which is not compatible to the Armada XP DDR init code, we need to introduce a new directory infrastructure. To support multiple Marvell DDR controller. This will be the new structure: drivers/ddr/marvell/axp Supporting Armada XP (AXP) devices (and perhaps Armada 370) drivers/ddr/marvell/a38x Supporting Armada 38x devices (and perhaps Armada 39x) Signed-off-by: Stefan Roese <sr@denx.de>
