[PATCH v6 00/12] Earlycon cleanup

From: Peter Hurley <hidden>

Also in: lkml

Hi Greg, Grant & Rob,

This patch series is a rebase of the v3 from April last year.

This patch series builds on my earlier "Extensible console matching &
direct earlycon" to add several useful features to earlycon:
* Proper port i/o configuration from DT node with of_serial properties
  (such as reg-io-width, reg-shift and reg-offset, and endianness)
* Proper console name & index initialization from earlycon name
  (for both command line and DT-defined earlycons)
* Support for DT 'stdout-path' options pass-through to earlycon setup
* Improved log messages for troubleshooting
* Support for multiple OF earlycon declarations so different
  compatible strings can specify the same OF earlycon

* Changes from v3
  - Added 32-bit big-endian support
  - Removed the omap8250 earlycon (will follow later)
* Changes from v4
  - Rolled in Rob's acks (thanks for reviewing this series)
  - Removed the conditional guard of of_fdt.h header inclusion (Rob's comment)
  - Left in the omap8250 earlycon (rebased w/o the wip so applies cleanly)
* Changes from v5
  - Builds :/
    "of: earlycon: of_setup_earlycon() requires CONFIG_OF_EARLY_FLATREE"
    didn't make it into v4 so I left it out of v5. That'll teach me.

Regards,
