* ddr: altera: Internal scc_mgr_apply_group_all_out_delay_add() cleanup part 1Marek Vasut2015-08-08-35/+9
| | | | | | | | | | | | | | Apparently, in case of the DQ and DM, the value if the new_delay variable is calculated, but the value is not used. Zap the entire code which does calculate the value. It is not clear to me whether or not the code is doing the right thing in the first place. Right now, it calls scc_mgr_load_dq() and scc_mgr_load_dm() respectively, but I suspect it might need to call scc_mgr_apply_group_dq_out1_delay() and scc_mgr_apply_group_dm_out1_delay() instead. This is something Altera must investigate. Signed-off-by: Marek Vasut <marex@denx.de>

* ddr: altera: Pluck out remaining sdr_get_addr() callsMarek Vasut2015-08-08-119/+75
| | | | | | | Remove the remaining invocations of sdr_get_addr() and the function itself. This makes the code a bit less cryptic. Signed-off-by: Marek Vasut <marex@denx.de>
* ddr: altera: Dissolve invocation of sdr_get_addr(&sdr_mgr_.*->.*)Marek Vasut2015-08-08-26/+26

* Makefile: Add target for building bootable SPL image for SoCFPGAMarek Vasut2015-08-08-0/+22
| | | | | | | | | | | | Add build target for generating boot partition images recognised by the SoCFPGA BootROM. The SoCFPGA BootROM expects four copies of the u-boot-spl-dtb.sfp at the beginning of boot partition. Those are u-boot-spl-dtb.bin augmented by a header with which the BootROM can work. The u-boot-dtb.img uImage is appended to this to produce a full boot partition image, the u-boot-with-spl-dtb.sfp . This is the name of the final target. Signed-off-by: Marek Vasut <marex@denx.de>
* arm: socfpga: config: Make CONFIG_SPI_FLASH_MTD usefulMarek Vasut2015-08-08-0/+4
| | | | | | | | Enable the mtdparts command and related options to make support for SPI NOR MTD useful in any way. With the mtdparts command in place, it is possible to use partition of the SPI NOR in U-Boot. Signed-off-by: Marek Vasut <marex@denx.de>
* arm: socfpga: config: Fix LOADADDRMarek Vasut2015-08-08-2/+2
| | | | | | | | | Setting LOADADDR to 0x8000 is a bad idea, it is very likely that some kind of overlap will happen. Move the LOADADDR 0x01000000 (16MiB from start of RAM) to make sure no overlap happens when loading kernel for example. Signed-off-by: Marek Vasut <marex@denx.de>
* arm: socfpga: config: Enable CONFIG_SPI_FLASH_BARMarek Vasut2015-08-08-0/+1
| | | | | | | This is needed to access broken (read: Micron) SPI flashes which are larger than 16 MiB and don't correctly support 4-byte addressing. Signed-off-by: Marek Vasut <marex@denx.de>
* arm: socfpga: config: Exclude CONFIG_SPI_FLASH_MTD from SPL buildMarek Vasut2015-08-08-0/+2
| | | | | | | We do not need full MTD support in the SPL build, it only adds size and is not usable in any way. Exclude it. Signed-off-by: Marek Vasut <marex@denx.de>
* arm: socfpga: config: Zap incorrect config optionsMarek Vasut2015-08-08-7/+2
| | | | | | | | | | | | | | There is no need to disable support for partitions in the SPL, we can support partitions in SPL perfectly well. This is likely some remnant from old times, so just remove this configuration option. Moreover, the CRC32 chunk size doesn't have to be adjusted anymore, since both the GD and malloc area are in RAM by the time this CRC check can be used and there's plenty of space. Zap this abomination as well. Signed-off-by: Marek Vasut <marex@denx.de>
* arm: socfpga: config: Move SPL GD and malloc to RAMMarek Vasut2015-08-08-6/+20
| | | | | | | | | | | Now that the SPL structure is organised such that it matches the U-Boot's SPL design, it is possible to use the option of relocating GD to RAM. And since we have GD in RAM, move malloc area to RAM as well. We point the malloc base pointer 1 MiB past U-Boot's load address. We use simple malloc for SPL because it is 3kiB smaller in terms of code size than regular malloc which was used thus far. Signed-off-by: Marek Vasut <marex@denx.de>
* arm: socfpga: misc: Reset ethernet from OFMarek Vasut2015-08-08-21/+51
| | | | | | | | | | | 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 Vasut2015-08-08-5/+3
| | | | | | | | | 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/+24
| | | | | | | | 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.

* arm: socfpga: spl: Add support for selecting boot device from BSELMarek Vasut2015-08-08-12/+23
| | | | | | | | Rework spl_boot_device() such that it reads the BSEL settings from system manager and decides from where to load U-Boot based on this information. Signed-off-by: Marek Vasut <marex@denx.de>
* arm: socfpga: spl: Add support for booting from QSPIMarek Vasut2015-08-08-1/+28
| | | | | | | Add code and configuration options to support booting from QSPI NOR. Enable support for booting from QSPI NOR. Signed-off-by: Marek Vasut <marex@denx.de>
* arm: socfpga: spl: Add support for booting from SD/MMCMarek Vasut2015-08-08-1/+37
| | | | | | | | | | Add code and configuration options to support booting from RAW SD/MMC card as well as for ext4/vfat filesystems. Enable support for booting from SD/MMC card, but don't enable the filesystem support just yet to retain compatibility with old SoCFPGA card format. Signed-off-by: Marek Vasut <marex@denx.de>
* arm: socfpga: spl: Remove custom linker scriptMarek Vasut2015-08-08-48/+0
| | | | | | | | Remove the custom SPL linker script, use the generic one instead. The custom script doesn't bring in anything new and is only burden to maintain. Signed-off-by: Marek Vasut <marex@denx.de>
* arm: socfpga: spl: Merge spl_board_init() into board_init_f()Marek Vasut2015-08-08-18/+12
| | | | | | | | | | The code in spl_board_init() should have been in board_init_f() from the beginning, since it is code which configures system and then starts DRAM. Thus, it cannot be in spl_board_init(), which is called from board_init_r() , which already expects a working DRAM. Signed-off-by: Marek Vasut <marex@denx.de>
* arm: socfpga: spl: Add missing reset logicMarek Vasut2015-08-08-1/+9
| | | | | | | | Make sure that all the peripherals are correctly reset and then brought out of reset in the SPL. Not going through proper reset cycle might leave the IP blocks in inconsistent state. Signed-off-by: Marek Vasut <marex@denx.de>
* arm: socfpga: spl: Configure SCU and NIC-301 earlyMarek Vasut2015-08-08-0/+22
| | | | | | | | | Configure the ARM SCU and NIC301 very early. The ARM SCU SNSAC register must be configured, so we can access all peripherals. The NIC-301 must be configured so that the BootROM is not mapped into the SDRAM address space. Signed-off-by: Marek Vasut <marex@denx.de>
