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. Signed-off-by: Tom Rini <trini@konsulko.com>

Move eSDHC adapter card identification to board files The eSDHC adapter card identification and multiplexing configuration through FPGA had been implemented in both common mmc driver and fsl_esdhc driver. However it is proper to move these code to board files and do it during board initialization. The FPGA registers are also board specific. This patch is to move eSDHC adapter card identification and multiplexing configuration from mmc driver to specific board files. And the option CONFIG_FSL_ESDHC_ADAPTER_IDENT is no longer needed.

dm: mmc: Allow disabling driver model in SPL At present if U-Boot proper uses driver model for MMC, then SPL has to also. While this is desirable, it places a significant barrier to moving to driver model in some cases. For example, with a space-constrained SPL it may be necessary to enable CONFIG_SPL_OF_PLATDATA which involves adjusting some drivers. Add new SPL versions of the options for DM_MMC, DM_MMC_OPS and BLK. By default these follow their non-SPL versions, but this can be changed by boards which need it.

spl: saveenv: adding saveenv support in SPL By default saveenv option is not supported for SPL. This patch enable the support for save environment variable for SPL build. Enable save environment support in SPL after setenv. By default the saveenv option is not provided in SPL, but some boards need this support in 'Falcon' boot, where SPL need to boot from different images based on environment variable set by OS. For example OS may set "reboot_image" environment variable to "recovery" inorder to boot recovery image by SPL. The SPL read "reboot_image" and act accordingly and change the reboot_image to default mode using setenv and save the environemnt.
