2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
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. Signed-off-by: Tom Rini <trini@konsulko.com>

2016-07-22i2c_eeprom: Add reading supportmario.six@gdsys.cc
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. Signed-off-by: Mario Six <mario.six@gdsys.cc> Reviewed-by: Simon Glass <sjg@chromium.org> Reviewed-by: Heiko Schocher <hs@denx.de>
2014-12-11dm: Add a simple EEPROM driverSimon Glass
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.
