This patch moves the davinci i2c_defs.h file to drivers.i2c directory.
It will allow to reuse the davinci_i2c driver for TI Keystone2 SOCs.
Not used "git mv" command to move the file because small part of
it with definitions specific for Davinci SOCs has to remain in the
arch/arm/include/asm/arch-davinci.

We previously only supported QSPI_1 (single) support. Add QSPI_4 (quad)
read support as well. This means we can be given one of two boot device
values, but don't care which it is, so perform a fixup on the QSPI_4
value. We add a qspiboot build target to better show how you would use
QSPI as a boot device in deployment. When we boot from QSPI, we can
check the environment for 'boot_os' to control Falcon Mode.

TI platforms such as OMAP5uevm, PandaBoard, use equivalent
logic to generate fake USB MAC address from device unique DIE ID.
Consolidate this to a generic location such that other TI platforms such
as BeagleBoard-XM can also use the same.
NOTE: at this point in time, I dont yet see a need for a generic dummy

Replace the custom bit manipulation function sr32() by standard I/O
accessors. A major motivation for this cleanup was the fact, that a
number of calls of that function resulted in 32 bit wide shift
operations on u32 data, which according to the C-ISO/IEC-9899-Standard
provokes undefined behaviour:
6.5.7 Bitwise shift operators
...
If the value of the right operand is negative or is greater
than or equal to the width of the promoted left operand, the
behavior is undefined.

The anadig_reg structure started at the wrong offset (fixed by adding
reserved_0x000[4]), was missing some reserved field required for
alignment purpose (reserved_0x094[3] between pll4_denom and pll6_ctrl)
and further contained a too short reserved field causing further miss-
alignment (reserved_0x0C4[7]). Also, rename all the reserved fields
and using a memory offset based scheme for.

This patch adds the groundwork for generating signed BootStream, which
can be used by the HAB library in i.MX28. We are adding a new target,
u-boot-signed.sb , since the process for generating regular non-signed
BootStream is much easier. Moreover, the signed bootstream depends on
external _proprietary_ _binary-only_ tool from Freescale called 'cst',
which is available only under NDA.
To make things even uglier, the CST or HAB mandates a kind-of circular
dependency. The problem is, unlike the regular IVT, which is generated
by mxsimage, the IVT for signed boot must be generated by hand here due
to special demands of the CST. The U-Boot binary (or SPL binary) and IVT
are then signed by the CST as a one block. But here is the problem. The
size of the entire image (U-Boot, IVT, CST blocks) must be appended at
the end of IVT. But the size of the entire image is not known until the
CST has finished signing the U-Boot and IVT. We solve this by expecting
the CST block to be always 3904B (which it is in case two files, U-Boot
and the hand-made IVT, are signed in the CST block).

Add support for serial console into the i.MX23/i.MX28 SPL. A full,
uncrippled serial console support comes very helpful when debugging
various spectacular hardware bringup issues early in the process.
Because we do not use SPL framework, but have our own minimalistic
SPL, which is compatible with the i.MX23/i.MX28 BootROM, we do not
use preloader_console_init(), but instead use a similar function to
start the console. Nonetheless, to avoid blowing up the size of the
SPL binary, this support is enabled only if CONFIG_SPL_SERIAL_SUPPORT
is defined, which is disabled by default.

When using HAB, there are additional special requirements on the placement of
U-Boot and the U-Boot SPL in memory. To fullfill these, this patch moves the
U-Boot binary a little further from the begining of the DRAM, so the HAB CST
and IVT can be placed in front of the U-Boot binary. This is necessary, since
both the U-Boot and the IVT must be contained in single CST signature. To
make things worse, the IVT must be concatenated with one more entry at it's
end, that is the length of the entire CST signature, IVT and U-Boot binary
in memory. By placing the blocks in this order -- CST, IVT, U-Boot, we can
easily align them all and then produce the length field as needed.
As for the SPL, on i.MX23/i.MX28, the SPL size is limited to 32 KiB, thus
we place the IVT at 0x8000 offset, CST right past IVT and claim the size
is correct. The HAB library accepts this setup.
Finally, to make sure the vectoring in SPL still works even after moving
the SPL from 0x0 to 0x1000, we add a small function which copies the
vectoring code and tables to 0x0. This is fine, since the vectoring code
is position independent.

U-Boot has supported two kinds of asm-offsets.h.
One is generic for all architectures and its source is located at
./lib/asm-offsets.c.
The other is SoC specific and its source is under SoC directory.
The problem here is that only boards with SoC directory can use
the asm-offsets infrastructure.
Putting asm-offsets.c right under CPU directory does not work.
Now a new demand is coming. PowerPC folks want to use asm-offsets.
But no PowerPC boards have SoC directory.
It seems inconsistent that some boards add asm-offsets.c to SoC
directoreis and some to CPU directories.
It looks more reasonable to put asm-offsets.c under arch/$(ARCH)/lib.
This commit merges asm-offsets.c under SoC directories into
arch/$(ARCH)/lib/asm-offsets.c.
By the way, I doubt the necessity of some entries in asm-offsets.c.
I am leaving refactoring to the board maintainers.
Please check "TODO" in the comment blocks in

The way that struct mmc was implemented was a bit of a mess;
configuration and internal state all jumbled up in a single structure.
On top of that the way initialization is done with mmc_register leads
to a lot of duplicated code in drivers.
Typically the initialization got something like this in every driver.
struct mmc *mmc = malloc(sizeof(struct mmc));
memset(mmc, 0, sizeof(struct mmc);
/* fill in fields of mmc struct */
/* store private data pointer */
mmc_register(mmc);
By using the new mmc_create call one just passes an mmc config struct
and an optional private data pointer like this:
struct mmc = mmc_create(&cfg, priv);
All in tree drivers have been updated to the new form, and expect
mmc_register to go away before long.
Changes since v1:
* Use calloc instead of manually calling memset.
* Mark mmc_register as deprecated.

When jumping from one sandbox U-Boot to another in sandbox, the RAM buffer
is preserved in the jump by using a temporary file. Add an option to tell
the receiving U-Boot to remove this file when it is no longer needed.
Similarly the old U-Boot image is left behind in this case. We cannot delete
it immediately since gdb cannot then find its debug symbols. Delete it just
before exiting.
Together these changes ensure that temporary files are removed both for
memory and U-Boot.

SDL (Simple DirectMedia Layer - see www.libsdl.org) is a library which
provides simple graphics and sound features. It works under X11 and also
with a simple frame buffer interface. It is ideally suited to sandbox
U-Boot since it fits nicely with the low-level feature set required by
U-Boot. For example, U-Boot has its own font drawing routines, its own
keyboard processing and just needs raw sound output.
We can use SDL to provide emulation of these basic functions for sandbox.
This significantly expands the testing that is possible with sandbox.
Add a basic SDL library which we will use in future commits.
