[U-Boot] [PATCH v2 0/7] usb: eth: introduce Moschip MCS7830 driver

[Gerhard Sittig <gsi@denx.de>]

this series
- does a little cleanup: BIT() and BITMASK() macros in common.h,
  no #ifdef for routine declarations in header files
- adds a new USB ethernet driver for adapters that are based on the
  MCS7730/7830/7832 chips
- enables the driver for those boards which previously had support for
  "all other" USB ethernet adapters
- updates the README.usb documentation file to list all available
  drivers for USB ethernet adapters

development and tests were done on a taskit stamp9g20 with Delock and
Logilink adapters, running TFTP transfers of a file as large as RAM is

there are several checkpatch warnings
- about CamelCase for NetReceive() and USB related structure members,
  which cannot get fixed as the names are in the established API
- about a multiple assignment for the "found" flags in the USB endpoint
  search, which I consider acceptable

version v2 addresses all received feedback:
- adjust the Cc: list (network custodian, BIT() macro committers,
  board maintainers)
- move the BIT() macro to the common.h header file
- reduce the number of timeouts, only "USB call" and "network
  link status" timeouts are left
- use errno.h codes instead of the unhelpful "-1" magic number
- factor out common PHY access code, fix the retry logic
- more straight forward init() callback and link status check,
  silent operation according to the U-Boot philosophy
- remove text fold markers
- kernel nano-doc style comments for data structures, global
  variables, and routines
- remove #ifdef from function prototypes in header files
- whitespace fixes (in the USB dongle list comments)
- switch the USB dongle list from sentinel terminated to "dense,
  useful data only" and iterate by means of ARRAY_SIZE()
- remove an ugly and non-obvious "unused" silencer, instead
  use the __maybe_unused decoration near the implementation
