i2c: i2c-mxs: Wait for I2C to empty queue
Make sure the I2C write queue is empty before leaving the mxs_i2c_write().
If we start and I2C write and only wait for ACK, the MXS I2C IP block may
enter next operation while still processing the write aftermath internally.
This will in turn disrupt one or more subsequent transfer(s).
A testcase for this issue is as such. This testcase is also interesting because
the first I2C_WRITE which becomes disruptive happens in the 'i2c read' command.
The 'i2c read' command first uses I2C_WRITE to send I2C address of the chip and
then uses I2C_READ to read data from the chip. After this command completes, the
'i2c probe' will use sequence of I2C_WRITE commands to probe the I2C bus. The
problem is that the first I2C_WRITE disrupted the I2C IP block operation and
this sideeffect propagates all the way to this next I2C_WRITE used by the 'i2c
probe' call. The result is the 'i2c probe' receives an ACK on I2C address 0x00,
even if this ACK was owned by the previous I2C_WRITE operation. Note that the
'i2c read' command must read from a valid I2C chip address.
Wrong:
> i2c probe
Valid chip addresses: 50 51
> i2c read 0x50 0x0.2 0x10 0x42000000
> i2c probe
Valid chip addresses: 00 50 51
With this patch
> i2c probe
Valid chip addresses: 50 51
> i2c read 0x50 0x0.2 0x10 0x42000000
> i2c probe

kbuild: change out-of-tree build
This commit changes the working directory
where the build process occurs.
Before this commit, build process occurred under the source
tree for both in-tree and out-of-tree build.
That's why we needed to add $(obj) prefix to all generated
files in makefiles like follows:
$(obj)u-boot.bin: $(obj)u-boot
Here, $(obj) is empty for in-tree build, whereas it points
to the output directory for out-of-tree build.
And our old build system changes the current working directory
with "make -C <sub-dir>" syntax when descending into the
sub-directories.
On the other hand, Kbuild uses a different idea
to handle out-of-tree build and directory descending.
The build process of Kbuild always occurs under the output tree.
When "O=dir/to/store/output/files" is given, the build system
changes the current working directory to that directory and
restarts the make.
Kbuild uses "make -f $(srctree)/scripts/Makefile.build obj=<sub-dir>"
syntax for descending into sub-directories.
(We can write it like "make $(obj)=<sub-dir>" with a shorthand.)
This means the current working directory is always the top
of the output directory.

(Delete cc-option in config.mk)
- Use cc-version defined in

- Move binutils-version and dtc-version to Kbuild.include

Makefile: move some variable definitions to the top Makefile
This commit moves some variable definitions from config.mk
to the top Makefile:
- HOSTCC, HOSTCFLAGS, HOSTLDFLAGS
- AS, LD, CC, CPP, etc.
- SHELL (renamed to CONFIG_SHELL)
I'd like to slim down config.mk file
because it is included from all recursive make.
It is redundant to re-define the variables
every time descending into sub directories.
We should rather define them at the top Makefile
and export them.
U-Boot makefiles has been used "SHELL" variable to store shell
chosen for the user, whereas Linux Kernel uses "CONFIG_SHELL".
We should never use "SHELL" variable because it is
a special variable for GNU Make.
Changing SHELL may cause unpredictable side effects
whose root cause is usually difficult to find.
We should use a generic variable name "CONFIG_SHELL".
We should not use the syntax as follows either:
rm -f $(obj)tools/env/{fw_printenv,fw_setenv}
This depends on "bash" although GNU Make generally
invokes "sh" to run the each rule.

arm/km: define fdt_high env variable and allow backwards compatibility
Add set_fdthigh subcommand to "subbootcmds" (release) so to set "fdt_high"
This is necessary on Kirkwood so that the FDT does not get relocated
above the memory limit that the kernel cannot access
(that is the memory part reserved for the switch).
This was tested on NUSA1, where it is necessary, and on ETER1, where it
doesn't seem to hurt.
We want the scripts to also work with older versions of u-boot, where:
a) set_fdthigh is not defined (will be default env for newer u-boots)
b) the fdt will not be available
For this reason, we use "set_fdthigh" to tell whether we are running
a newer (FDT-aware) u-boot or not.
So if "set_fdthigh" runs successfully or arch != arm we try loading
the fdt; otherwise we proceed normally.
Notice how, contrary to release mode, set_fdthigh will _not_ be part of
subbootcmds for develop and ramfs, but will be executed as part of
"tftpfdt".
Since this is only needed for kirkwood cards, and it prevents the kernel
from booting on QorIQ (though it seemed to work on ETER1), we change
its definition in the default env for powerpc so that the value is only
