2015-08-08arm: socfpga: system: Rework sysmgr_enable_warmrstcfgio()Marek Vasut
Rework sysmgr_enable_warmrstcfgio() into sysmgr_config_warmrstcfgio(), which allows both enabling and disabling the warm reset config I/O functionality. Signed-off-by: Marek Vasut <marex@denx.de>
2015-08-08arm: socfpga: scan: Zap iocsr_scan_chain*_table()Marek Vasut
Introduce accessor iocsr_get_config_table() for retrieving IOCSR config tables. This patch is again trimming down the namespace polution. The IOCSR config tables are used only by scan manager, they are generated by qts and are board specific. Before this patch, the approach to use these tables in scan manager was to define an extern variable to silence the compiler and compile board-specific iocsr_config.c into U-Boot which defined those extern variables. Furthermore, since these are tables and the scan manager needs to know the size of those tables, iocsr_config.h is included build-wide. This patch wraps all this into a single accessor which takes the scan chain ID and returns pointer to the table and it's size. All this is wrapped in wrap_iocsr_config.c board-specific file. The file includes the iocsr_config.c (!) to access the original tables and transitively iocsr_config.h . It is thus no longer necessary to include iocsr_config.h build-wide and the namespace polution is trimmed some more. Signed-off-by: Marek Vasut <marex@denx.de>
2015-08-08arm: socfpga: scan: Staticize scan_mgr_io_scan_chain_prg()Marek Vasut
This function is never used outside of scan_manager.c , so make it static. Zap the prototype in scan_manager.h and move the documentation above the function. Make the documentation kerneldoc compliant. Signed-off-by: Marek Vasut <marex@denx.de>
2015-08-08arm: socfpga: clock: Clean up pll_config.hMarek Vasut
Extract the clock configuration horribleness caused by pll_config.h in the following manner. First of all, introduce a few new accessors which return values of various clocks used in clock_manager.c and use them in clock_manager.c . These accessors replace those few macros which came from pll_config.h originally. Also introduce an accessor which returns the struct cm_config default configuration for the clock manager used in SPL. The accessors are implemented in a board-specific wrap_pll_config.c file, whose sole purpose is to include the qts-generated pll_config.h and provide only the necessary values to the clock manager. The purpose of this design is to limit the scope of inclusion for the pll_config.h , which thus far was included build-wide and poluted the namespace. With this change, the inclusion is limited to just the new wrap_pll_config.c file, which in turn provides three simple functions for the clock_manager.c to use.

2015-08-08arm: socfpga: clock: Get rid of cm_config_t typedefMarek Vasut
Get rid of this cryptic typedef and replace it with explicit struct cm_config. Signed-off-by: Marek Vasut <marex@denx.de>
2015-08-08arm: socfpga: reset: Add SDMMC, QSPI and DMA definesMarek Vasut
Add SDMMC, QSPI and DMA reset defines. These are needed by SPL so that we can boot from SD card and QSPI. Signed-off-by: Marek Vasut <marex@denx.de>
2015-08-08arm: socfpga: reset: Add function to reset add peripheralsMarek Vasut
Add socfpga_per_reset_all() function to reset all peripherals but the L4 watchdog. This is needed in the SPL. Signed-off-by: Marek Vasut <marex@denx.de>
2015-08-08arm: socfpga: reset: Replace ad-hoc reset functionsMarek Vasut
Replace all those ad-hoc reset functions, which were all copies of the same invocation of clrbits_le32() anyway, with one single unified function, socfpga_per_reset(), with necessary parameters. Signed-off-by: Marek Vasut <marex@denx.de>
2015-08-08arm: socfpga: reset: Implement unified function to toggle resetMarek Vasut
Implement function socfpga_per_reset(), which allows asserting or de-asserting reset of each reset manager peripheral in a unified manner. Use this function throughout reset manager. Signed-off-by: Marek Vasut <marex@denx.de>
2015-08-08arm: socfpga: reset: Start reworking the SoCFPGA reset managerMarek Vasut
Implement macro SOCFPGA_RESET(name), which produces an abstract reset number. Implement macros which allow extracting the reset offset in permodrstN register and which permodrstN register the reset is located in from this abstract reset number. Use these macros throughout the reset manager. Signed-off-by: Marek Vasut <marex@denx.de>
2015-08-08arm: socfpga: reset: Add missing reset manager regsMarek Vasut
Define two missing reset manager registers, which are in the SoCFPGA CV datasheet. Signed-off-by: Marek Vasut <marex@denx.de>
2015-08-08ddr: altera: Move struct sdram_prot_rule prototypeMarek Vasut
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>
2015-08-08arm: socfpga: Move sdram_config.h to board dirMarek Vasut
This file is absolutelly positively board specific, so move it into the correct place. Signed-off-by: Marek Vasut <marex@denx.de>
2015-08-08driver/ddr/altera: Add DDR driver for Altera's SDRAM controllerDinh Nguyen
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>
