* arm: socfpga: Handle phy-mode OF property for GMACsMarek Vasut2016-04-10-3/+36
| | | | | | | | | | | | | | | Thus far, the socfpga init code had hard-coded the configuration of the ethernet PHY interface to RGMII in the ethernet registers in sysmgr space, so PHYs connected in another modes did not work. This patch fixes support for configurations where the ethernet PHYs are connected over MII/GMII/RMII interfaces by parsing the phy-mode OF property of the GMACs and configuring the ethernet registers in sysmgr space accordingly.

* arm: socfpga: Fix ethernet reset handlingMarek Vasut2016-02-24-2/+7
| | | | | | | | | | | | | | | | | | The following patch caused cpu_eth_init() to not be called anymore for DM-capable boards: commit c32a6fd07b1839e4a45729587ebc8e1c55601a4d Date: Sun Jan 17 14:51:56 2016 -0700 net: Don't call board/cpu_eth_init() with driver model This breaks ethernet on SoCFPGA, since we use that function to un-reset the ethernet blocks.

| | | | | | | | | In order to re-use as much Cyclone5 and Arria5 code as possible to support the Arria10 platform, we need to wrap some of the code with #ifdef's.

| | | | | | | | | 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>
* arm: socfpga: enable data/inst prefetch and shared override in the L2Dinh Nguyen2015-10-17-0/+12
| | | | | | | | | | | | | | | | | | | | Update the L2 AUX CTRL settings for the SoCFPGA. Enabling D and I prefetch bits helps improve SDRAM performance on the platform. Also, we need to enable bit 22 of the L2. By not having bit 22 set in the PL310 Auxiliary Control register (shared attribute override enable) has the side effect of transforming Normal Shared Non-cacheable reads into Cacheable no-allocate reads. Coherent DMA buffers in Linux always have a Cacheable alias via the kernel linear mapping and the processor can speculatively load cache lines into the PL310 controller. With bit 22 cleared, Non-cacheable reads would unexpectedly hit such cache lines leading to buffer corruption. Signed-off-by: Dinh Nguyen <dinguyen@opensource.altera.com>

* arm: socfpga: Do not call board_init_r() from board_init_f()Marek Vasut2015-09-04-2/+0
| | | | | | | | | | | Instead of calling board_init_r() directly from board_init_f(), just return from board_init_f(). This will make the code continue executing in crt0.S _main(), from which the board_init_r() is called. This patch aligns the SoCFPGA SPL with the correct SPL design as well as reduces the stack utilisation slightly.

| | | | | | | | | | This fix makes sure that the ISWGRP0 and ISWGRP1 registers are correctly inited. In case those registers are not initialized, it is not possible to access the registers synthesised in the FPGA through the bridges. Any such access produces data abort.

* arm: socfpga: Make the pinmux table const u8Marek Vasut2015-08-23-6/+4
| | | | | | | | | | | 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>

| | | | | | | | | Add script which loads the QTS-generated sources and headers and converts them into sensible format which can be used with much more easy in mainline U-Boot.

* arm: socfpga: Split Altera socfpga into AV and CV SoCDKMarek Vasut2015-08-23-2/+2
| | | | | | | | | | | | | | | | | | The board/altera/socfpga directory is not a generic SoCFPGA machine anymore, but instead it represents the Altera SoCDK board. To make matters more complicated, it represents both CycloneV and ArriaV variant. On the other hand, nowadays, the content of this board directory is mostly comprised of QTS-generated header files, while all the generic code is in arch/arm/mach-socfpga already. Thus, this patch splits the board/altera/socfpga into a separate board directory for ArriaV SoCDK and CycloneV SoCDK, so that each can be populated with the correct QTS-generated header files for that particular board.

* arm: socfpga: Unbind CPU type from board typeMarek Vasut2015-08-23-8/+18
| | | | | | | | | | | | | | | | | | | The CONFIG_TARGET_SOCFPGA_CYCLONE5 and CONFIG_TARGET_SOCFPGA_ARRIA5 selected both a board and a CPU. This is not correct as these macros are supposed to select only board. All would be good, if QTS-generated header files didn't check for these macros exactly to determine if the platform is Cyclone V or Arria V. Thus, for the sake of compatibility with not well fleshed out header file generator, this patch makes these two macros into a stub config option and introduces new CONFIG_TARGET_SOCFPGA_CYCLONE5_SOCDK and CONFIG_TARGET_SOCFPGA_ARRIA5_SOCDK targets, which select the previous stub config option. The result is that compatibility with QTS is preserved and the new CONFIG_TARGET_* select actual target boards. Signed-off-by: Marek Vasut <marex@denx.de>
* arm: socfpga: Move wrappers into platform directoryMarek Vasut2015-08-23-0/+545
| | | | | | | | | Move the wrappers for QTS-generated files into platform directory out of the board directory. The trick here is to add -I to CFLAGS such that it points to the board directory in source tree and thus the qts/ directory there is still reachable. Signed-off-by: Marek Vasut <marex@denx.de>
* arm: socfpga: Fix delay in clock managerMarek Vasut2015-08-23-7/+5

* arm: socfpga: Fix delay in freeze controllerMarek Vasut2015-08-23-7/+5
| | | | | | | | | | | | Based on observation, this udelay(20) was apparently too high and caused subsequent failure to calibrate DDR when U-Boot was compiled with certain toolchains. Lowering this delay fixed the problem. Instead of permanently lowering the delay, calculate the correct delay based on the original comment, that is, obtain EOSC1 frequency and use it to calculate the precise delay.

| | | | | | | | | | | Clean up the horrible macros present in the scan_manager.h .
