* arm: mvebu: Add complete SDRAM ECC scrubbingStefan Roese2015-08-17-2/+2
| | | | | | | | | | | | 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>
* arm: mvebu: sdram: Enable ECC support on Armada XPStefan Roese2015-08-17-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
* arm: mvebu: drivers/ddr: Move Armada XP DDR init code into new directoryStefan Roese2015-07-23-0/+15419
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>
