* arm: socfpga: Add socfpga_spim_enable() to reset_manager.cStefan Roese2014-11-071-0/+3
| | | | | | | | | | | | | | | | | This function will be needed by the upcoming Designware master SPI driver. As the SPI master controller is held in reset by the current Preloader implementation. So we need to release the reset for the driver to communicate with the controller. This function is called from arch_early_init_r() if the SPI driver is enabled.

* arm: socfpga: Add DT support for SoCFPGA and add socfpga_socrates targetStefan Roese2014-11-071-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch includes the latest DT sources for socfpga from the current Linux kernel. And enables CONFIG_OF_CONTROL for the new build target "socfpga_socrates" (the EBV SoCrates board) to make use of this new DT support. Until this patch, the only SoCFPGA U-Boot target in mainline is "socfpga_cyclone5". This build target is not (yet) changed to support DT. So nothing changes for this target. Even though the long-term goal should be to move all SoCFPGA targets over to DT. One of the reasons to enable DT support in SoCFPGA is, that I need to support multiple different SPI controllers for this platform. This is the QSPI Cadence controller and the Designware SPI master controller. Both are implemented in the SoCFPGA. And enabling both controllers is only possible by using the new driver model (DM). The DM SPI code only supports DT based probing. So it was easier to move SoCFPGA to DT than to add the (deprecated) platform-data based probing to the DM SPI suport. Note that the image with the dtb embedded is u-boot-dtb.img. This needs to be used now for those DT enabled boards instead of u-boot.img.

| | | | | | | | | | | | | Switch to the common spl.h file and zap the arch/spl.h . Since the arch/spl.h contained various ad-hoc symbols, zap those symbols as well and rework the board configuration a little so it doesn't depend on them.

* arm: socfpga: misc: Add proper ethernet initializationPavel Machek2014-10-061-0/+9
| | | | | | | | | | | | | | | | | | | | | Add function to initialize the EMAC blocks upon board startup. The preprocessor guards against building on SoCFPGA-VT and against SPL build are not needed as those are handled implicitly via both SPL framework and the socfpga_cyclone5.h config file, which will not define CONFIG_DESIGNWARE_ETH if building for SoCFPGA-VT. We cannot handle two EMAC ethernet blocks yet, therefore the ifdefs. Once there is hardware using both EMAC blocks, this ifdef will have to go.
