[PATCH v4 0/6] Add Cortina Access basic DM drivers

[Alex Nemirovsky]

Cortina Access management has decided that we want to add formal
upstream support of u-boot going forward for our line of SoCs
and evaluation boards.

Our line of SoC’s all begin with the “CA” designation
followed by 4 digits.  i.e. CAxxxx. The CAxxxx series supports
both ARM and MIPS ISA based custom cores.

All our drivers have cross platform support for both CPU ISAs.
They will be placed in the normal drivers tree in u-boot.

In addition, our SoCs and development boards share common Cortina specific
features which are not driver related. Those changes will be maintained
in board/cortina/common. While specific development boards will be
in board/cortina/board_name.

We would like to have a git-mailrc alias of "cortina" to allow us to better
maintain and support our boards and common features found in the
board/cortina subtree.


Changes in v4:
- clean up presidio_asic.h per trini recommendations
- use autogen savedefconfig instead of manual maintained file

Changes in v3:
- Remove CA ARM and MIPS common subdirectories from board/cortina/common
  after further discussions with trini
- clean up comment blocks
- fix rmw of baud rate bitfield change
- fixed dts closing bracket indentation
- presidio.h: remove deadcode from presidio.h
- presidio.h: remove CA_REG_READ/CA_REG_WRITE wrapper macros
- presidio.h: remove CA77xx define replace use CA common Kconfig
  SoC selection instead
- select SOC_CA7774 via board's Kconfig
- select BIT64 via board's Kconfig instead of presidio.h

Changes in v2:
- Modified filepath for CA ARM and MIPS per trini's recommendation
- Rename driver in DT namespace for consistency between all
  CA drivers.
- Remove blank line after SPDX identifier
- Remove Authorship as it is already recorded within Git and is redundant
- Replace printf() as debug()
- Rename driver in DT namespace for consistency between all
  CA drivers.
- Remove blank line after SPDX identifier
- Remove authorship comment as it is already recorded within Git
  and is redundant
- Use setbits_32() for read-modify-write operation.
- Rename driver in DT namespace for consistency between all
   CA drivers.
- Remove blank line after SPDX identifier
- Remove authorship comment as it is already recorded within Git
  and is redundant
- Merge serial_cortina.h reg defines into serial_cortina.c
- Modify ca_serial_pending() and API to get resource.
