9ef9fe3455 ARM: socfpga: Rename the gen5 sdram driver to more specific name
Current sdram driver is only applied to gen5 device, hence it is better
to rename sdram driver to more specific name which is related to gen5
device.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

89a54abf1b ddr: altera: Configuring SDRAM extra cycles timing parameters
To enable configuration of sdr.ctrlcfg.extratime1 register which enable
extra clocks for read to write command timing. This is critical to
ensure successful LPDDR2 interface

042ff2d0fa ddr: altera: sequencer: Wrap misc remaining macros
Introduce structure socfpga_sdram_misc_config to wrap the remaining
misc configuration values in board file. Again, introduce a function,
socfpga_get_sdram_misc_config(), which returns this the structure. This
is almost the final step toward wrapping the nasty QTS generated macros
in board files and reducing the pollution of the namespace.

10c14261f3 ddr: altera: sequencer: Wrap IO_* macros
Introduce structure socfpga_sdram_io_config to wrap the IO configuration
values in board file. Introduce socfpga_get_sdram_io_config() function,
which returns this the structure. This is another step toward wrapping
the nasty QTS generated macros in board files and reducing the pollution
of the namespace.

d718a26b0c ddr: altera: sequencer: Wrap RW_MGR_* macros
Introduce structure socfpga_sdram_rw_mgr_config to wrap the RW manager
configuration values in board file. Introduce a complementary function,
socfpga_get_sdram_rwmgr_config(), which returns this the structure.
This is another step toward wrapping the nasty QTS generated macros
in board files and reducing the pollution of the namespace.

04955cf247 ddr: altera: sequencer: Wrap ac_rom_init and inst_rom_init
Introduce two wrapper functions, socfpga_get_seq_ac_init() and
socfpga_get_seq_inst_init() to avoid direct inclusion of the
sequencer_auto_ac_init.h and sequencer_auto_inst_init.h QTS
generated files. This reduces namespace pollution again.

5af914189e ddr: altera: sdram: Introduce socfpga_sdram_get_config()
Introduce socfpga_sdram_get_config() function implement in a board file,
which returns the socfpga_sdram_config structure. This is the last step
in cleaning up the socfpga_mmr_init_full(), but not the last step which
allows removing the inclusion of sdram.h from drivers/ddr/altera/sdram.c
thus far.

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.

family. This patch configures the SDRAM controller based on a configuration
file that is generated from the Quartus tool, sdram_config.h.
