Various Makefiles: Add SPDX-License-Identifier tags

2015-11-10T14:19:52Z

After consulting with some of the SPDX team, the conclusion is that Makefiles are worth adding SPDX-License-Identifier tags too, and most of ours have one. This adds tags to ones that lack them and converts a few that had full (or in one case, very partial) license blobs into the equivalent tag. Cc: Kate Stewart Signed-off-by: Tom Rini

drivers/ddr/fsl_ddr: Make SR_IE configurable

ddr: altera: Replace float multiplication with integer one

2015-08-23T09:56:19Z

This gem is really really rare, there was an actual float used in the Altera DDR init code, which pulled in floating point ops from the libgcc, just wow. Since we don't support floating point operations the same way Linux does not support them, replace this with an integer multiplication and division combo. This removes some 2kiB of size from the SPL as the floating point ops are no longer pulled in from libgcc. This was detected by enabling CONFIG_USE_PRIVATE_LIBGCC=y , which does not contain the floating point bits. Signed-off-by: Marek Vasut

arm: mvebu: Add complete SDRAM ECC scrubbing

2015-08-17T16:49:33Z

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 Cc: Luka Perkov

arm: mvebu: sdram: Enable ECC support on Armada XP

2015-08-17T16:41:33Z

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 Cc: Luka Perkov

ddr: altera: sequencer: Clean checkpatch issues

2015-08-08T12:14:30Z

Fix most of the dangling checkpatch issues, no functional change. There are still 7 warnings, 1 checks , but those are left in place for the sake of readability of the code. Signed-off-by: Marek Vasut Acked-by: Dinh Nguyen

ddr: altera: sequencer: Pluck out misc macros from code

2015-08-08T12:14:29Z

Actually convert the sequencer code to use socfpga_sdram_misc_config instead of the various macros. This is just an sed exercise here, no manual coding needed. This patch actually removes the need to include any board-specific files in sequencer.c , so sequencer.c namespace is now no longer poluted by QTS-generated macros.
