8137af19e7 arm64: Add tool to statically apply RELA relocations
ARM64 uses the newer RELA-style relocations rather than the older REL.
RELA relocations have an addend in the relocation struct, rather than
expecting the loader to read a value from the location to be updated.

While this is beneficial for ordinary program loading, it's problematic
for U-Boot because the location to be updated starts out with zero,
rather than a pre-relocation value.  Since we need to be able to run C
code before relocation, we need a tool to apply the relocations at
build time.

In theory this tool is applicable to other newer architectures (mainly
64-bit), but currently the only relocations it supports are for arm64,
and it assumes a 64-bit little-endian target.  If the latter limitation
is ever to be changed, we'll need a way to tell the tool what format
the image is in.  Eventually this may be replaced by a tool that uses
libelf or similar and operates directly on the ELF file.  I've written
some code for such an approach but libelf does not make it easy to poke
addresses by memory address (rather than by section), and I was
hesitant to write code to manually parse the program headers and do the
update outside of libelf (or to iterate over sections) -- especially
since it wouldn't get test coverage on things like binaries with
multiple PT_LOAD segments.  This should be good enough for now to let
the manual relocation stuff be removed from the arm64 patches.

ab71188ce8 mmc: add setdsr support
The eMMC and the SD-Card specifications describe the optional SET_DSR command.
During measurements at our lab we found that some cards implementing this feature
having really strong driver strengts per default. This can lead to voltage peaks
above the specification of the host on signal edges for data sent from a card to
the host.

Since availability of a given card type may be shorter than the time a certain
hardware will be produced it is useful to have support for this command (Alternative
would be changing termination resistors and adapting the driver strength of the
host to the used card.)

Following proposal for an implementation:

- new field that reflects CSD field DSR_IMP in struct mmc
- new field for design specific DSR value in struct mmc
- board code can set DSR value in mmc struct just after registering an controller
- mmc_startup sends the the stored DSR value before selecting a card, if DSR_IMP is set

Additionally the mmc command is extended to make is possible to play around with different
DSR values.

The concept was tested on a i.MX53 based platform using a Micron eMMC card where the default
DSR is 0x0400 (12mA) but in our design 0x0100 (0x0100) were enough. To use this feature for
instance on a mx53loco one have to add a call to mmc_set_dsr() in board_mmc_init() after
calling fsl_esdhc_initialize() for the eMMC.

2a7a210e2c mmc/dwmmc: use bounce buffer for data exchange between CPU and MMC controller
Bounce buffer implementation takes care of proper data buffer alignemt
and correct flush/invalidation of data cache at once so we no longer
depend on input data variety and make sure CPU and MMC controller deal
with expected data in case of enabled data cache.

Bounce buffer requires to add its definition (CONFIG_BOUNCE_BUFFER) in
board configuration, otherwise corresponding library won't be compiled
and linker will fail to build resulting executable.

Difference since v1 - fixed compile-time warning with type casting to
"void *":

Slight edit to remove UTF8 characters in the commit message.
