42f477f0ab misc: i2c_eeprom: Add fallbacks
Add some fallback functions for when i2c_eeprom is disabled. This allows
code to reference i2c_eeprom_* functions without needing to check
whether support has been compiled in.

dda3b38920 misc: i2c_eeprom: Make i2c_eeprom_write use a const buf
i2c_eeprom_ops->write uses a const buf, so use one for the wrapper
function as well.

185f812c41 doc: replace @return by Return:
Sphinx expects Return: and not @return to indicate a return value.

find . -name '*.c' -exec \
sed -i 's/^\(\s\)\*\(\s*\)@return\(\s\)/\1*\2Return:\3/' {} \;

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

d7e28918aa i2c_eeprom: Add reading support
This patch implements the reading functionality for the generic I2C
EEPROM driver, which was just a non-functional stub until now.

Since the page size will be of importance for the writing support, we
add suitable members to the private data structure to keep track of it.

Compatibility strings for a range of at24c* chips are added.

20142019a9 dm: Add a simple EEPROM driver
There seem to be a few EEPROM drivers around - perhaps we should have a
single standard one? This simple driver is used for sandbox testing, but
could be pressed into more active service.
