34122eb262 arm: socfpga: reset: Add SDMMC, QSPI and DMA defines
Add SDMMC, QSPI and DMA reset defines. These are needed by SPL
so that we can boot from SD card and QSPI.

3191611a05 arm: socfpga: reset: Add function to reset add peripherals
Add socfpga_per_reset_all() function to reset all peripherals
but the L4 watchdog. This is needed in the SPL.

292260ca21 arm: socfpga: reset: Repair bridge reset handling
The current bridge reset code, which de-asserted the bridge reset,
was activelly polling whether the FPGA is programmed and ready and
in case it was (!), the code called hang(). This makes no sense at
all. Repair it such that the code instead checks whether the FPGA
is programmed, but without any polling involved, and only if it is
programmed, it de-asserts the reset.

a71df7aa4f arm: socfpga: reset: Replace ad-hoc reset functions
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.

bdfc2ef64a arm: socfpga: reset: Implement unified function to toggle reset
Implement function socfpga_per_reset(), which allows asserting or
de-asserting reset of each reset manager peripheral in a unified
manner. Use this function throughout reset manager.

1115cd2de7 arm: socfpga: reset: Start reworking the SoCFPGA reset manager
Implement macro SOCFPGA_RESET(name), which produces an abstract
reset number. Implement macros which allow extracting the reset
offset in permodrstN register and which permodrstN register the
reset is located in from this abstract reset number. Use these
macros throughout the reset manager.

42f7ebb82b ddr: altera: Move struct sdram_prot_rule prototype
Move the structure prototype from sdram.h header file into sdram.c
source file, since it is used only there and for local purpose only.
There is no point in having it global.

While at this move, fix the data types in the structure from uintNN_t
to uNN and fix the coding style a bit.

9bbd2132e3 driver/ddr/altera: Add DDR driver for Altera's SDRAM controller
This patch enables the SDRAM controller that is used on Altera's SoCFPGA
family. This patch configures the SDRAM controller based on a configuration
file that is generated from the Quartus tool, sdram_config.h.

a26cd04920 arch: Make board selection choices optional
By making the board selections optional, every defconfig will include
the board selection when running savedefconfig so if a new board is
added to the top of the list of choices the former top's defconfig will
still be correct.

7865f4b0b6 ARM: socfpga: move board select into mach-socfpga/Kconfig
Switch to a more standard way of board select; put the SoC select
into arch/arm/Kconfig and move the board select menu under
arch/arm/mach-socfpga/Kconfig.

Also, consolidate SYS_BOARD, SYS_VENDOR, SYS_SOC, SYS_CONFIG_NAME.
