mtd: spi_dataflash: Use spi read then write

2019-09-16T02:39:22Z

Now, we have spi_write_then_read routine that would handle spi_xfer handling based on the tx_buf and rx_buf parameters. So, replace individual flash read/write/cmd transfer call with spi_write_then_read.

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12Z

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

2016-11-19T03:11:53Z

Flash id detection should be the first step to enumerate the connected flash on the board, once ie done checking with respective id codes locally in the driver all this should be part of jedec_probe instead of id detection and validated through flash_info{} table separatly.
