-Subject: [PATCH] fw_env: make flash_io() take buffer as an argument
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-It's usually easier to understand code & follow it if all arguments are
-passed explicitly. Many coding styles also discourage using global
-variables.
-
-Behaviour of flash_io() was a bit unintuitive as it was writing to a
-buffer referenced in a global struct. That required developers to
-remember how it works and sometimes required hacking "environment"
-global struct variable to read data into a proper buffer.

-Subject: [PATCH] fw_env: simplify logic & code paths in the fw_env_open()
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Environment variables can be stored in two formats:
-1. Single entry with header containing CRC32
-2. Two entries with extra flags field in each entry header
-
-For that reason fw_env_open() has two main code paths and there are
-pointers for CRC32/flags/data.
-
-Previous implementation was a bit hard to follow:
-1. It was checking for used format twice (in reversed order each time)
-2. It was setting "environment" global struct fields to some temporary
-   values that required extra comments explaining it
-
-This change simplifies that code:
-1. It introduces two clear code paths
-2. It sets "environment" global struct fields values only once it really
-   knows them
-
-To be fair there are *two* crc32() calls now and an extra pointer
-variable but that should be cheap enough and worth it.

-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-A new DT binding for describing environment data block has been added in
-Linux's commit 5db1c2dbc04c ("dt-bindings: nvmem: add U-Boot environment
-variables binding"). Once we get a proper Linux NVMEM driver it'll be
-possible to use Linux's binary interface for user-space as documented
-in the:
-https://www.kernel.org/doc/html/latest/driver-api/nvmem.html
-
-This commits makes fw_env fallback to looking for a compatible NVMEM
-device in case config file isn't present. In a long term this may make
-config files redundant and avoid code (info) duplication.
