a9f7be509a mmc: rpmb: Fix driver routing memory alignment with tmp buffer
Fix mmc_rpmb_route_frames() implementation to comply with most MMC
drivers that expect some alignment of MMC data frames in memory.

When called from drivers/tee/optee/rpmb.c, the address passed is not
aligned properly. OP-TEE OS inserts a 6-byte header before a raw RPMB
frame which makes RPMB data buffer not 32bit aligned. To prevent breaking
ABI with OPTEE-OS RPC memrefs, allocate a temporary buffer to copy the
data into an aligned memory.

Many RPMB drivers implicitly expect 32bit alignment of the eMMC frame
including arm_pl180_mmci.c, sandbox_mmc.c and stm32_sdmmc2.c

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.

use 'int' instead of 'long' type for the 'long' is not 4-byte

cf92e05c01 Move ALLOC_CACHE_ALIGN_BUFFER() to the new memalign.h header
Now that we have a new header file for cache-aligned allocation, we should
move the stack-based allocation macro there also.

2b9912e6a7 includes: move openssl headers to include/u-boot
commit 18b06652cd "tools: include u-boot version of sha256.h"
unconditionally forced the sha256.h from u-boot to be used
for tools instead of the host version. This is fragile though
as it will also include the host version. Therefore move it
to include/u-boot to join u-boot/md5.h etc which were renamed
for the same reason.
