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>

Since we now have clock driver for the RCar Gen3 , add support for enabling the clock into the SH SDHI driver to prevent hacks in the board files.

2017-08-17mmc: sh_sdhi: Fix the ACMD handlingMarek Vasut
The command handling in this driver is awful, esp. because the driver depends on command numbers to determine whether this is APPCMD or not. Also, handling of command RSP response types is totally wrong. This patch at least plucks out some of the custom command encoding and fixes the APPCMD handling. The RSP handling still needs work, yet that might not be needed as it turns out the uniphier-sd.c driver is in much better shape and supports the same IP, so we might be able to just drop this driver in favor of the uniphier one.

Add MMC DM and DT probing support into the SH SDHI driver. This patch abstracts out the common bits of the send command and set ios functions, so they can be used both by DM and non DM setups and adds the DM probe support.

R-Car Gen3 series have four SD card interfaces (SDHI0 to SDHI3), two of which can also be used as MMC interfaces (SDHI2 and SDHI3). This adds High-speed mode SD clock frequency between 25MHz and 50MHz, 8bit/4bit bus width, high capacity and low voltage device support.

Building w/ GCC v5.2, the SD card access is broken due to invalid data in the response command reconstructed at the end of sh_sdhci_get_response(). Add a memory barrier between the two main steps of this function to ensure the resp[] table content is consistent before bits reordering.
