ddr: altera: Stratix10: Add multi-banks DRAM size check
Stratix 10 maps dram from 0 to 128GB. There is a 2GB hole
in the memory for peripherals and other IO from 2GB to 4GB.
However the dram controller ignores upper address bits for
smaller dram configurations. Example: a 4GB dram
maps to multiple locations, every 4GB on the address.

To clean up reset handling for socfpga gen5, port the DDR driver to DM
using UCLASS_RAM and implement proper reset handling.
This gets us rid of one ad-hoc call to socfpga_per_reset().
The gen5 driver is implemented in 2 distinct files. One of it (containing
the calibration training) is not touched much and is kept at using
hard coded addresses since the code grows even more otherwise.
SPL is changed from calling hard into the DDR driver code to just
probing UCLASS_RESET and UCLASS_RAM. It is happy after finding a RAM
driver after that.

reset: socfpga: add reset handling for old kernels
This adds code to take peripherals out of reset based on an environment
variable. This is in preparation for removing the code that does this from
SPL.
However, some drivers even in current Linux cannot handle peripheral reset,
so until this works, we need a compatibility workaround.
This workaround is implemented in the 'assert' and 'remove' callbacks of
this reset driver: the 'assert' callback does not disable peripherals that
were already taken out of reset, while the 'remove' callback, which is
called on OS_PREPARE, deasserts all peripheral resets if the environment
variable "socfpga_legacy_reset_compat" is set to 1, which is what the gen5
SPL did up to now.
This is in preparation to clean up the SPL and implementing proper reset
handling for U-Boot.

arm: socfpga: gen5: deassert peripheral reset by default
To keep the current behaviour of taking all peripherals out of reset
before booting the OS before removing that code from socfpga gen5 SPL,
this enables the new behaviour by default for all gen5 boards by adding
the environment variable "socfpga_legacy_reset_compat=1" to the default
environment.
This can be overridden in board config files or by saving an environment
without this variable enabled.

The only member of this driver's priv struct is a pointer, which is
called 'membase'. However, since this driver handles multiple sub-
architectures, this is not the base address from dts but the base
address of some common registers of those sub-arches.
Reflect this better in sourcecode by renaming 'membase' to 'modrst_base'.

The SPL for socfpga gen5 currently takes all peripherals out of reset
unconditionally. To implement proper reset handling for peripherals,
the reset node has to be provided with the SPL dts.
In preparation to move the DDR driver to DM, the sdr node is required
in SPL, too.
This patch adds "u-boot,dm-pre-reloc" to U-Boot specific dtsi addon
files so that the reset manager and SDR driver correctly probe in SPL.
It centralizes these settings into a common file since in contrast to
boot-type specific nodes, "soc", "rst" and "sdr" are always needed.

usb: kbd: Properly translate up/down arrow keys
So far arrows key pressed on an USB keyboard got translated to some
low ASCII control sequences (Ctrl+N, Ctrl+P). Some programs understand
these codes, but the standard for those keys is to use ANSI control
sequences for cursor movement (ESC [ A).
Our own boot menu is a victim of this, currently we cannot change the

Since we already implement a queue for USB key codes, we can just insert
the three character ANSI sequence into the key buffer. This fixes the
bootmenu, and is more universal for other users (UEFI) as well.
