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.

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.

SH4 and SH4A are compatible. But some instructions are different from these.
In Linux kernel, It is treated as a separate CPU, but for now, I think that
there is no need to divide especially in the U-Boot.
This removes CONFIG_SH4A definition from source code, SH4A is treated as SH4.
And this fix white space.

Add a simple TPM emulator for sandbox. It only supports a small subset of
TPM operations. However, these are enough to perform common tasks.
Note this is an initial commit to get this working, but it could use
cleaning up (for example constants instead of open-coded values).

It is useful to be able to save and restore the RAM contents of sandbox
U-Boot either for setting up tests, for later analysys, or for chaining
together multiple tests which need to keep the same memory contents.
Add a function to provide a memory file for U-Boot. This is read on
start-up and written when shutting down. If the file does not exist
on start-up, it will be created when shutting down.

With sandbox, errors and problems may be reported before console_init_f()
is executed. For example, an argument may not parse correctly or U-Boot may
panic(). At present this output is swallowed so there is no indication what
is going wrong.
Adjust the console to deal with a very early sandbox setup, by detecting that
there is no global_data yet, and calling os functions in that case.

Provide a way to use any host file or device as a block device in U-Boot.
This can be used to provide filesystem access within U-Boot to an ext2
image file on the host, for example.
The support is plumbed into the filesystem and partition interfaces.
We don't want to print a message in the driver every time we find a missing

This patch fixes allow for the DeviceTree and initrd relocation fixing
the boot of FSL 3.10.9-1.0.0-alpha kernel.
This changes following boards:
- mx6sabreauto
- mx6sabresd
- wandboard
- udoo
- nitrogen6x
- cgtqmx6eval
The reasoning, as explained by Hui Liu, is:
,----
| The FDT blob will be placed at DDR physical addr: 0x11000000. When Linux kernel
| Boot up, it will decompress the compressed kernel image and place the decompressed
| kernel image at the low end of the DDR memory and start running from it. If the
| decompressed kernel image is bigger for example than 16M, it may over written the
| fdt blob which u-boot loaded to the DDR memory @0x11000000 with fdt_addr=0x11000000
|
| To expand the fdt_addr from 0x11000000 to 0x18000000, which can avoid the override
| Since we will not likely have one kernel image larger than 128MB.
