* arm: socfpga: Nuke useless includeMarek Vasut2016-04-10-12/+0
| | | | | | | | | | The dwmmc.h include was forgotten during the migration of dwmmc probing to DM. Since the shiny DM is in place now, remove this relic of the past. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Dinh Nguyen <dinguyen@opensource.altera.com> Cc: Chin Liang See <clsee@altera.com>

* ARM: socfpga: rename the cyclone5 and arria5 base address fileDinh Nguyen2015-11-30-0/+0
| | | | | | | | | When adding support for the Arria10 platform, we're going to name the file base_addr_a10.h, so to be systematic about it, rename the socfpga_base_addr.h to be base_addr_ac5.h for the Arria5 and Cyclone5 platform.

* arm: socfpga: reset: correct dma, qspi, and sdmmc reset bit definesDinh Nguyen2015-11-03-3/+3
| | | | | | | The DMA, QSPI, and SD/MMC reset bits are located in the permodrst register, not the mpumodrst. So the bank for these reset bits should be 1, not 0. Signed-off-by: Dinh Nguyen <dinguyen@opensource.altera.com>
* mmc: dw_mmc: Probe the MMC from OFMarek Vasut2015-09-04-1/+1
| | | | | | | | | | | | | Rework the driver to probe the MMC controller from Device Tree and make it mandatory. There is no longer support for probing from the ancient qts-generated header files. This patch now also removes previous temporary workaround.

* arm: socfpga: Make the pinmux table const u8Marek Vasut2015-08-23-2/+1
| | | | | | | | | | | Now that we're actually converting the QTS-generated header files, we can even adjust their data types. A good candidate for this is the pinmux table, where each entry can have value in the range of 0..3, but each element is declared as unsigned long. By changing the type to u8, we can save over 600 Bytes from the SPL, so do it. This patch also constifies the array. Signed-off-by: Marek Vasut <marex@denx.de>
* arm: socfpga: scan: Add code to get FPGA IDDinh Nguyen2015-08-08-0/+1
| | | | | | | Add code to get the FPGA type for Altera's SoCFPGA family of FPGA. The code uses the scan manager to send jtag pulses that will return the FPGA ID. Signed-off-by: Dinh Nguyen <dinguyen@opensource.altera.com>
* arm: socfpga: scan: Clean up horrible macrosMarek Vasut2015-08-08-42/+0
| | | | | | | | | | | Clean up the horrible macros present in the scan_manager.h . Firstly, the function scan_mgr_io_scan_chain_prg() is static, yet all the macros are used only within it, thus there is no point in having them in the header file. Moreover, the macros are just making the code much less readable, so remove them instead. Signed-off-by: Marek Vasut <marex@denx.de> Acked-by: Dinh Nguyen <dinguyen@opensource.altera.com>
* arm: socfpga: scan: Clean up scan_chain_engine_is_idle()Marek Vasut2015-08-08-9/+0
| | | | | | | | | | Rework this function so it's clear that it is only polling for certain bits to be cleared. Add kerneldoc. Fix it's return value to be either 0 on success and -ETIMEDOUT on error and propagate this through the scan manager code.

* ddr: altera: sequencer: Wrap misc remaining macrosMarek Vasut2015-08-08-0/+17
| | | | | | | | | | | Introduce structure socfpga_sdram_misc_config to wrap the remaining misc configuration values in board file. Again, introduce a function, socfpga_get_sdram_misc_config(), which returns this the structure. This is almost the final step toward wrapping the nasty QTS generated macros in board files and reducing the pollution of the namespace.

| | | | | | | | | | | Introduce structure socfpga_sdram_io_config to wrap the IO configuration values in board file. Introduce socfpga_get_sdram_io_config() function, which returns this the structure.

* ddr: altera: sequencer: Wrap RW_MGR_* macrosMarek Vasut2015-08-08-0/+64
| | | | | | | | | | | Introduce structure socfpga_sdram_rw_mgr_config to wrap the RW manager configuration values in board file. Introduce a complementary function, socfpga_get_sdram_rwmgr_config(), which returns this the structure.

* ddr: altera: sequencer: Wrap ac_rom_init and inst_rom_initMarek Vasut2015-08-08-0/+3
| | | | | | | | | | Introduce two wrapper functions, socfpga_get_seq_ac_init() and socfpga_get_seq_inst_init() to avoid direct inclusion of the sequencer_auto_ac_init.h and sequencer_auto_inst_init.h QTS generated files. This reduces namespace pollution again. Signed-off-by: Marek Vasut <marex@denx.de> Acked-by: Dinh Nguyen <dinguyen@opensource.altera.com>

* ddr: altera: sdram: Introduce socfpga_sdram_get_config()Marek Vasut2015-08-08-0/+42
| | | | | | | | | | Introduce socfpga_sdram_get_config() function implement in a board file, which returns the socfpga_sdram_config structure. This is the last step in cleaning up the socfpga_mmr_init_full(), but not the last step which allows removing the inclusion of sdram.h from drivers/ddr/altera/sdram.c thus far.

* arm: socfpga: system: Clean up pinmux_config.cMarek Vasut2015-08-08-3/+2
| | | | | | | | | | | | | | | Implement new accessor, sysmgr_get_pinmux_table(), used to obtain pinmux table and it's size from the QTS-generated pinmux_config.c. The target here is again to get rid of poluting global namespace by including the pinmux_config.h into it. Furthermore, the pinmux_config.h declares some CONFIG_HPS_* macros, which are explicitly useless to us in U-Boot. Instead, U-Boot does use DT to detect exactly these configuration options. This patch makes sure that while this QTS-generated file can stay in the tree, these obscure macros do not ooze into the namespace anymore. Signed-off-by: Marek Vasut <marex@denx.de>
* arm: socfpga: system: Rework sysmgr_enable_warmrstcfgio()Marek Vasut2015-08-08-1/+1
| | | | | | | | 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>
* arm: socfpga: scan: Zap iocsr_scan_chain*_table()Marek Vasut2015-08-08-9/+3
| | | | | | | | | | | | | | | | | | | | | | 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>
* arm: socfpga: scan: Staticize scan_mgr_io_scan_chain_prg()Marek Vasut2015-08-08-11/+0
| | | | | | | | 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>
* arm: socfpga: clock: Clean up pll_config.hMarek Vasut2015-08-08-1/+7
| | | | | | | | | | | | | | | | | | | | | | | 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.

* arm: socfpga: reset: Replace ad-hoc reset functionsMarek Vasut2015-08-08-7/+0
| | | | | | | | 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>
* arm: socfpga: reset: Implement unified function to toggle resetMarek Vasut2015-08-08-0/+2
