b65d5209b3 fdt: arm: Drop device tree padding
The 4KB padding doesn't seem necessary since we don't normally adjust the
control device tree file within U-Boot. Also drop the memory table space.

9091400859 dm: ns16550: Support CONFIG_SYS_NS16550_MEM32 with driver model
This option is used by some boards, so support it with driver model. This
is really ugly - we should rewrite this driver once all users are moved to
driver model.

32ba8952cb arm: spl: Add an API to detect when U-Boot is started from SPL
For secure boot systems it is common to have a read-only U-Boot which starts
the machine and jumps to a read-write U-Boot for actual booting the OS. This
allows the read-write U-Boot to be upgraded without risk of permanently
bricking the machine. In the event that the read-write U-Boot is corrupted,
the read-only U-Boot can detect this with a checksum and boot into a
recovery flow.

To support this, add a way to detect when U-Boot is run from SPL as opposed
to some other method, such as booted directly (no SPL) or started from
another source (e.g. a primary U-Boot). This works by putting a special value
in r0.

For now we rely on board-specific code to actually check the register and
set a flag. At some point this could be generalised, perhaps by using a spare
register and passing a flag to _main and/or board_init_f().

This commit does not implement any feature, but merely provides the API for
boards to implement.

0751b13806 sunxi: Enable CONFIG_SYS_64BIT_LBA when AHCI is used
Due to absence of CONFIG_SYS_64BIT_LBA, u-boot-sunxi currently has
no support for the (GPT) partioning scheme of large disks > 2TB.
While the AHCI driver seems to handle this nicely, the problem is
that lbaint_t values get truncated to 32-bit.

This patch sets CONFIG_SYS_64BIT_LBA from sunxi_common.h for all
SoCs that support AHCI (CONFIG_SUNXI_AHCI).

635c2515c3 tegra: spi: Drop the claim_bus() method to correct delays
At present the driver does not properly honour the requested SPI CS
deactivation delay since the SPI bus is changed in the claim_bus() method.

Everything the claim_bus() method does can be done when the device is probed
(setting the speed and mode) and at the start of a new transfer (where the
fifo_status is already cleared). So drop this method.

Also, until the delay is complete, we should not touch the bus, so make sure
that spi_cs_activate() is called before other things are done in the xfer()
method.

20c20826ef Kconfig: Enable usage of escape char '\' in string values
I might have missed something, but I failed to use the escape char '\'
in strings. To pass a printf format string like "foo %d bar\n" via
Kconfig to the code.

Right now its not possible to use the escape character '\' in Kconfig
string values correctly to e.g. set this string value "test output\n".
The '\n' will be converted to 'n'.

The current implementation removes some of the '\' chars from the input
string in conf_set_sym_val(). Examples:

'\'	-> ''
'\\'	-> '\'
'\\\'	-> '\'
'\\\\'	-> '\\'
...

And then doubles the backslash chars in the output string in
sym_escape_string_value(). Example:

'\'	-> ''	-> ''
'\\'	-> '\'	-> '\\'
'\\\'	-> '\'	-> '\\'
'\\\\'	-> '\\'	-> '\\\\'
...

As you see in these examples, its impossible to generate a single '\'
charater in the output string as its needed for something like '\n'.

This patch now changes this behavior to not drop some backslashes in
conf_set_sym_val() and to not add new backslashes in the resulting
output string. Removing the function sym_escape_string_value()
completely as its not needed anymore.
