Add a sandbox I2C emulation device which emulates a real-time clock. The
clock works off an offset from the current system time, and supports setting
and getting the clock, as well as access to byte-width regisers in the RTC.
It does not support changing the system time.
This device can be used for testing the 'date' command on sandbox, as well
as the RTC uclass.

Add a uclass for real-time clocks which support getting the current time,
setting it and resetting the chip to a known-working state. Some RTCs have
additional registers which can be used to store settings, so also provide
an interface to these.

We don't need to use u8, and if we avoid it, it isn't so much of a problem
that rtc.h includes this header. With this change we can include rtc.h from
sandbox files.

Most callers unpack the structure and pass each member. It seems better to
pass the whole structure instead, as with the C library. Also add an rtc_
prefix.

Rename this function so that it is clear that it is provided by the RTC.
Also return an error when it cannot function as expected. This is unlikely
to occur since it works for dates since 1752 and many RTCs do not support
such old dates. Still it is better to be accurate.

At present this driver has a few test features. They are needed for running
the driver model unit tests but are confusing and unnecessary if using
sandbox at the command line. Add a flag to enable the test mode, and don't

By removing this default build target, the "u-boot.kwb" target is not
automatically generated. This fixes a temporary build error when using
out-of-tree builds, as buildman does per default (reported by Simon).
When the full SPL support is added for these targets with the DDR training
code, the "u-boot-spl.kwb" image will be generated automatically.
Users providing a special bin_hdr binary (binary.0) file can always add
this binary file and generate the full firmware image by issuing the
"make u-boot.kwb" command directly.

This patch adds support for the Marvell DB-88F6820-GP Armada A38x
evaluation board.
Supported peripherals are:
- UART
- Ethernet (mvneta)
- I2C
- SPI (including SPI NOR flash)
Please note that this board support right now only supports the
main U-Boot. Without the bin_hdr integration (DDR training etc). This
will be added in a few days / weeks to complete this board port. But
till then this U-Boot version can be run on the target via the
original Marvell U-Boot via this command:
tftpboot 4000000 db-88f6820-gp/u-boot.bin;go 4000000

With the introduction of the Armada 38x support, its necessary to change
the mvneta ethernet driver init call from always 4 times to a
configurable value. Lets make this init call more flexible by moving
the actually used devices to the config header.
Additionally this patch takes care of the slightly different base
addresses for the ethernet controllers on A38x.

Starting part of device initialization sets the init_in_progress flag
only if the MMC card did not yet come to ready state and needs to continue
polling. If the card is SD or if the MMC card became ready quickly,
the flag is not set and (if using pre-initialization) the starting
phase will be re-executed from mmc_init function.
Set the init_in_progress flag in all non-error cases. Also, move flags
setting statements around so that the flags are not set in error paths.
Also, IN_PROGRESS return status becomes unnecessary, so get rid of it.

The polling loops in sd_send_op_cond and mmc_complete_op_cond functions
check the ready flag state at the end of the loop, that is after executing
a delay inside the loop, which, in case of exiting with no error,
is not needed. Also, one of these loops, as well as the loop
in mmc_send_status, have the delay just before exiting on timeout
conditions.
Restructure all these loops to check the respective conditions before making
a delay for the next loop pass, and to appropriately exit without the delay.

Some MMC cards come to ready state quite quickly, so that the respective
flag appears to be set in mmc_send_op_cond already. In this case trying
to continue polling the card with CMD1 in mmc_complete_op_cond is incorrect
and may lead to unpredictable results. So check the flag before polling
and skip it appropriately.

The previous change to use 'ocr' structure field for storing send_op_cond
command response also stopped using command response directly
outside of mmc_send_op_cond_iter(). Now it becomes possible to use
command structure in mmc_send_op_cond_iter() locally, removing a necessity
to pass it as an argument from the caller.
