* arm: socfpga: Nuke useless includeMarek Vasut2016-04-10-1/+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: 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. Invoke the ethernet reset function from arch_misc_init() instead to fix the breakage.

* arm: socfpga: Actually enable L2 cacheMarek Vasut2015-12-22-2/+11
| | | | | | | | | The L2 cache was never enabled in the v7_outer_cache_enable(), fix this and enable the L2 cache. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Dinh Nguyen <dinguyen@opensource.altera.com> Cc: Chin Liang See <clsee@altera.com>
* arm: socfpga: Remove cpu_mmc_init()Marek Vasut2015-12-07-11/+0
| | | | | | | | | | | | This function triggers the registration of the dwmmc driver on SoCFPGA, but this is not needed in case the driver is correctly probed from DT.

* 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>
* mmc: dw_mmc: Probe the MMC from OFMarek Vasut2015-09-04-8/+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: misc: Add support for printing FPGA typeDinh Nguyen2015-08-08-0/+63
| | | | | | | | | | Add code which uses the new functions for obtaining FPGA ID from the scan manager. This new code prints the FPGA model attached to the SoCFPGA during boot and sets environment variable "fpgatype", which can be used to determine the FPGA model in U-Boot scripts.

* arm: socfpga: Add temporary workaround for missing SD/MMC patchesMarek Vasut2015-08-08-0/+6
| | | | | | | | | | | | Add a small workaround into the platform code which forces the SDMMC into 8-bit mode (the default configuration for all socfpga platforms) to work around breakage caused by missing patches in mainline which switch the probing of SD/MMC to OF instead of static configuraiton. The patches will hit mainline after the SPL series, so to avoid build issues, add this small temporary workaround. Signed-off-by: Marek Vasut <marex@denx.de>
* arm: socfpga: misc: Reset ethernet from OFMarek Vasut2015-08-08-19/+49
| | | | | | | | | | | Reset the GMAC ethernets based on the "resets" OF node instead of ad-hoc hardcoded values in the U-Boot code. Since we don't have a proper reset framework in place yet, we have to do this slightly ad-hoc parsing of the OF tree instead.

* arm: socfpga: misc: Probe ethernet GMAC from OFMarek Vasut2015-08-08-3/+1
| | | | | | | | | The GMAC can now be probed from OF, so enable DM ethernet and remove the old ad-hoc designware_initialize() invocation. Signed-off-by: Marek Vasut <marex@denx.de> Cc: Dinh Nguyen <dinguyen@opensource.altera.com> Cc: Joe Hershberger <joe.hershberger@ni.com>
* arm: socfpga: misc: Export bootmode into environment variableMarek Vasut2015-08-08-11/+23
| | | | | | | | setenv an environment variable called "bootmode" , which contains the board boot mode. This can be in turn used in scripts to determine from where to load kernel and such. Signed-off-by: Marek Vasut <marex@denx.de>
* arm: socfpga: misc: Add support for printing boot modeMarek Vasut2015-08-08-0/+13
| | | | | | | Add support for printing from which device the SoCFPGA board booted. This decodes the BSEL settings and prints it in human readable form. Signed-off-by: Marek Vasut <marex@denx.de>
* arm: socfpga: misc: Fix warm resetMarek Vasut2015-08-08-0/+10
| | | | | | | | | | | | | | Write necessary magic value into the Warm Boot from ON-Chip RAM group Enable register to enable Warm reset support. Instead of doing this in the reset_cpu() function, we do it in arch early init to avoid breaking old kernel code which expects this magic value to be already written into this register. This magic is originally excavated from common/spl/spl.c in the u-boot port from altera, where this value was written just before the SPL jumped to actual U-Boot in the RAM.

| | | | | | | | 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>
