* ddr: altera: Move struct sdram_prot_rule prototypeMarek Vasut2015-08-081-0/+13
| | | | | | | | | | | Move the structure prototype from sdram.h header file into sdram.c source file, since it is used only there and for local purpose only. There is no point in having it global. While at this move, fix the data types in the structure from uintNN_t to uNN and fix the coding style a bit. Signed-off-by: Marek Vasut <marex@denx.de>
* arm: socfpga: Move sdram_config.h to board dirMarek Vasut2015-08-081-1/+6
| | | | | | | This file is absolutelly positively board specific, so move it into the correct place. Signed-off-by: Marek Vasut <marex@denx.de>

* driver/ddr/altera: Add DDR driver for Altera's SDRAM controllerDinh Nguyen2015-08-081-0/+799
| | | | | | | | This patch enables the SDRAM controller that is used on Altera's SoCFPGA family. This patch configures the SDRAM controller based on a configuration file that is generated from the Quartus tool, sdram_config.h. Signed-off-by: Dinh Nguyen <dinguyen@opensource.altera.com>
* drivers/ddr/fsl: Adjust bstopre valueYork Sun2015-08-032-5/+7
| | | | | | | | | By default the bstopre value has been set to 0x100, used to be 1/4 value of refint. Modern DDR has increased the refresh time. Adjust to 1/4 of refresh interval dynamically. Individual board can still override this value in board ddr file, or to use auto-precharge. Signed-off-by: York Sun <yorksun@freescale.com>
* arm: mvebu: a38x: Use correct PEX register access macrosStefan Roese2015-07-231-5/+0
| | | | | | | Remove the incorrect PEX macros from the DDR header. And insert the correct ones in ctrl_pex.h instead. Signed-off-by: Stefan Roese <sr@denx.de>
* arm: mvebu: Add Armada 38x DDR3 training code from Marvell bin_hdrStefan Roese2015-07-2343-0/+17368
| | | | | | | | | | | | | | | | | | This patch adds the DDR3 setup and training code taken from the Marvell U-Boot repository. This code used to be included as a binary (bin_hdr) into the Armada A38x boot image. Not linked with the main U-Boot. With this code addition and the serdes/PHY setup code, the Armada A38x support in mainline U-Boot is finally self-contained. So the complete image for booting can be built from mainline U-Boot. Without any additional external inclusion. Note: This code has undergone many hours (days!) of coding-style cleanup and refactoring. It still is not checkpatch clean though, I'm afraid. As the factoring of the code has so many levels of indentation that many lines are longer than 80 chars. Signed-off-by: Stefan Roese <sr@denx.de>
* arm: mvebu: drivers/ddr: Move Armada XP DDR init code into new directoryStefan Roese2015-07-2321-0/+0
| | | | | | | | | | | | | | | | 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>
* driver/ddr/fsl: Add a hook to update SPD addressYork Sun2015-07-201-0/+8
| | | | | | | | In case SPD address changes between board revisions, updating SPD address can be called from board file. Signed-off-by: York Sun <yorksun at freescale.com> Signed-off-by: Prabhakar Kushwaha <prabhakar at freescale.com>
* arm: mvebu: db-mv784mp-gp: Fix ECC I2C addressStefan Roese2015-05-051-1/+1
| | | | | | | | The macro to select the I2C address for ECC bus-width detection was defined incorrectly for the Marvell DB-MV784MP-GP board. This patch changes the macro to the correct value to fix this issue. Signed-off-by: Stefan Roese <sr@denx.de>
* driver/ddr/fsl: Add workaround for DDR erratum A008511York Sun2015-04-231-1/+95
| | | | | | | | This erratum only applies to general purpose DDR controllers in LS2. It shouldn't be applied to DP-DDR controller. Check DDRC versoin number before applying workaround. Signed-off-by: York Sun <yorksun@freescale.com>
* driver/ddr/fsl: Add built-in memory test for DDR4 driverYork Sun2015-04-231-0/+73
| | | | | | | | | Add built-in memory test to catch errors after DDR is initialized, before any other transactions. To enable this test, define CONFIG_FSL_DDR_BIST. An environmental variable "ddr_bist" is checked before starting test. It takes a while (several seconds) depending on system memory size. Signed-off-by: York Sun <yorksun@freescale.com>
* driver/ddr/fsl: Fix driver to support empty first slotYork Sun2015-04-235-28/+56
| | | | | | | | CS0 was not allowed to be empty by u-boot driver in the past to simplify the driver. This may be inconvenient for some debugging. This patch lifts the restrictions. Controller interleaving still requires CS0 populated. Signed-off-by: York Sun <yorksun@freescale.com>
* drivers/ddr/fsl: Update DDR driver for DDR4York Sun2015-04-234-10/+88
| | | | | | | | | | Add/update registers for DDR4, including DQ mappings. Allow raw timing method used for all controllers. Update mode_9 register to 0x500 for improved stability. Check DDR controller version number individually in case a SoC has multiple DDR controllers of different versions. Increase read-write turnaround for DDR4 high speeds.

* MPC8541/MPC8555: Enable SS_EN in DDR_SDRAM_CLK_CNLT registerCurt Brune2015-04-201-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to the MPC8555/MPC8541 reference manual the SS_EN (source synchronous enable) bit in the DDR_SDRAM_CLK_CNLT register must be set during initialization. >From section 9.4.1.8 of that manual: Source synchronous enable. This bit field must be set during initialization. See Section 9.6.1, "DDR SDRAM Initialization Sequence," details. 0 - Reserved 1 - The address and command are sent to the DDR SDRAMs source synchronously. In addition, Freescale application note AN2805 is also very clear that this bit must be set. This patch reverts a change introduced by commit 457caecdbca3df21a93abff19eab12dbc61b7897. Testing Done: Compiled targets CONFIG_TARGET_MPC8555CDS and CONFIG_TARGET_MPC8541CDS and inspected the generated assembly code to verify the SS_EN bit was being set. There is one extra instruction emitted: fff9b774: 65 29 80 00 oris r9,r9,32768 Compiled the CONFIG_TARGET_MPC8548CDS target and verified that no additional instructions were emitted related to this patch. Booted an image on a MPC8541 based board successfully. Signed-off-by: Curt Brune <curt@cumulusnetworks.com> Reviewed-by: York Sun <yorksun@freescale.com>
* driver/ddr/fsl: Add sync of refreshYork Sun2015-02-242-0/+59
| | | | | | | Add sync of refresh for multiple DDR controllers. DDRC initialization needs to complete first. Code is re-ordered to keep refresh close. Signed-off-by: York Sun <yorksun@freescale.com>

* driver/ddr/fsl: Adjust CAS to preamble override for emulatorYork Sun2015-02-241-1/+5
| | | | | | | | | On ZeBu emulator, CAS to preamble overrides need to be set to satisfy the timing. This only impact platforms with CONFIG_EMU. These should be set before MEM_EN is set. Signed-off-by: York Sun <yorksun@freescale.com>
