Several inline functions in this file reference undefined functions in
U-Boot. For example:atomic-long.h:73:9: warning: implicit declaration of function
'atomic64_sub_and_test'
atomic-long.h:80:9: warning: implicit declaration of function
'atomic64_dec_and_test'
atomic-long.h:87:9: warning: implicit declaration of function
'atomic64_inc_and_test'Handle this the same as the 32 bit build by wrapping these functions in
a __UBOOT__ check.Signed-off-by: Bradley Bolen

Certain GPIO devices have the capability to switch their GPIOs into
open-drain mode, that is, instead of actively driving the output
(Push-pull output), the pin is connected to the collector (for a NPN
transistor) or the drain (for a MOSFET) of a transistor, respectively.
The pin then either forms an open circuit or a connection to ground,
depending on the state of the transistor.This patch adds functions to the GPIO uclass to switch GPIOs to
open-drain mode on devices that support it.Signed-off-by: Mario Six

Many drivers use a common form of offset + flags for device
tree nodes. e.g.:
This patch adds a common implementation of this type of parsing
and calls it when a gpio driver doesn't supply its' own xlate
routine.This will allow removal of the driver-specific versions in a
handful of drivers and simplify the addition of new drivers.Signed-off-by: Eric Nelson

We can use GPIOs as binary digits for reading 'strapping' values. Each GPIO
is assigned a single bit and can be set high or low on the circuit board. We
already have a legacy function for reading these values. Add one that

Before relocation we need to reserve memory for the video driver frame
buffers so that they can use this memory when they start up (after
relocation). Add a call to the uclass to permit this.The current top and bottom of the region is stored in global_data so that
it can be checked post-relocation to ensure enough memory is available. No
video device should be probed before relocation.Signed-off-by: Simon Glass

Secure memory is at the end of memory, separated and reserved
from OS, tracked by gd->secure_ram. Secure memory can host
MMU tables, security monitor, etc. This is different from PRAM
used to reserve private memory. PRAM offers memory at the top
of u-boot memory, not necessarily the real end of memory for
systems with very large DDR. Using the end of memory simplifies
MMU setup and avoid memory fragmentation."bdinfo" command shows gd->secure_ram value if this memory is
marked as secured.Signed-off-by: York Sun

It is useful to be able to record console output and provide console input
via a buffer. This provides sandbox with the ability to run a command and
check its output. If the console is set to silent then no visible output
is generated.This also provides a means to fix the problem where tests produce unwanted
output, such as errors or warnings. This can be confusing. We can instead
set the console to silent and record this output. It can be checked later
in the test if required.It is possible that this may prove useful for non-test situations. For
example the console output may be suppressed for normal operations, but
recorded and stored for access by the OS. That feature is not implemented
at present.Signed-off-by: Simon Glass

At present in SPL we place the device tree immediately after BSS. This
avoids needing to copy it out of the way before BSS can be used. However on
some boards BSS is not placed with the image - e.g. it can be in RAM if
available.Add an option to tell U-Boot that the device tree should be placed at the
end of the image binary (_image_binary_end) instead of at the end of BSS.Note: A common reason to place BSS in RAM is to support the FAT filesystem.
We should update the code so that it does not use so much BSS.Signed-off-by: Simon Glass

this is an atempt to make the export of functions typesafe.
I replaced the jumptable void ** by a struct (jt_funcs) with function pointers.
The EXPORT_FUNC macro now has 3 fixed parameters and one
variadic parameter
The first is the name of the exported function,
the rest of the parameters are used to format a functionpointer
in the jumptable,the EXPORT_FUNC macros are expanded three times,
1. to declare the members of the struct
2. to initialize the structmember pointers
3. to call the functions in stubs.cSigned-off-by: Martin Dorwig
