Add 64-bit data for memory commands, such as md, mw, mm, cmp. The new
size ".q " is introduced.
For 64-bit architecture, 64-bit data is enabled by default, by detecting
compiler __LP64__. It is optional for other architectures.

This documentation pertains to the planned implementation of driver model
in U-Boot for each subsystem, but it has not been superseded. It is
probably better to have this documentation in the source code for each
subsystem where possible, so that docbook will pick it up. Where this does
not make sense, new documentation can be placed in some suitable file in
doc/driver-model.

Now that named GPIO banks are supported, along with a way of obtaining
the status of a GPIO (input or output), we can provide an enhanced
GPIO command for driver model. Where the driver provides its own operation
for obtaining the GPIO state, this is used, otherwise a generic version
is sufficient.

Add driver model support for GPIOs. Since existing GPIO drivers do not use
driver model, this feature must be enabled by CONFIG_DM_GPIO. After all
GPO drivers are converted over we can perhaps remove this config.
Tests are provided for the sandbox implementation, and are a sufficient
sanity check for basic operation.
The GPIO uclass understands the concept of named banks of GPIOs, with each
GPIO device providing a single bank. Within each bank the GPIOs are numbered
using an offset from 0 to n-1. For example a bank named 'b' with 20
offsets will provide GPIOs named b0 to b19.
Anonymous GPIO banks are also supported, and are just numbered without any
prefix.
Each time a GPIO driver is added to the uclass, the GPIOs are renumbered
accordinging, so there is always a global GPIO numbering order.

As an example of how to write a uclass and a driver, provide a demo version
of each, accessible through the 'demo' command.
To use these with driver model, define CONFIG_CMD_DEMO and CONFIG_DM_DEMO.
The two demo drivers are enabled with CONFIG_DM_DEMO_SIMPLE and
CONFIG_DM_DEMO_SHAPE.

Add some tests of driver model functionality. Coverage includes:
- basic init
- binding of drivers to devices using platform_data
- automatic probing of devices when referenced
- availability of platform data to devices
- lifecycle from bind to probe to remove to unbind
- renumbering within a uclass when devices are probed/removed
- calling driver-defined operations
- deactivation of drivers when removed
- memory leak across creation and destruction of drivers/uclasses
- uclass init/destroy methods
- automatic probe/remove of children/parents when needed
This function is enabled for sandbox, using CONFIG_DM_TEST.

U-Boot now uses errors defined in include/errno.h which are negative
integers. Commands which fail need to report the error and return 1
to indicate failure. Add this functionality in cmd_process_error().
For now this merely reports the error number. It would be possible
also to produce a helpful error message by storing the error strings
in U-Boot.

Now we have two different frameworks for doing the same thing.
I'd like to propose to drop nand_spl framework.
How about deleting it before v2014.07 release?
In the interim, this commit will display a warning message
when compiling nand_spl board.
Now we have 19 nand_spl boards:
MPC8315ERDB_NAND
SIMPC8313_LP
SIMPC8313_SP
MPC8536DS_NAND
MPC8569MDS_NAND
MPC8572DS_NAND
P1023RDS_NAND
P1011RDB_NAND
P1020RDB_NAND
P2010RDB_NAND
P2020RDB_NAND
acadia_nand
bamboo_nand
canyonlands_nand
glacier_nand
haleakala_nand
kilauea_nand
rainier_nand
sequoia_nand
They must be ported to SPL before the deadline,
otherwise they will be removed.

When we tell the compiler to optimize for ARMv7 (and ARMv6 for that
matter) it assumes a default of SCTRL.A being cleared and unaligned
accesses being allowed and fast at the hardware level. We set this bit
and must pass along -mno-unaligned-access so that the compiler will
still breakdown accesses and not trigger a data abort.
To better help understand the requirements of the project with respect
to unaligned memory access, the
Documentation/unaligned-memory-access.txt file has been added as
doc/README.unaligned-memory-access.txt and is taken from the v3.14-rc1
tag of the kernel.

This change is binary-invariant when only .dynsym, .dynstr,

Sections .hash, .got.plt, .dynbss and .ARM.exidx are also

Commit 6789e84ecaa8f45d053084e08c381284a04abff7 (i2c, omap24xx:
convert driver to new mutlibus/mutliadapter framework) intended to
make I2C driver compatible with latest changes. It unfortunately has
had a impact on size on SPL as well. For example on SDP4430,
32032 bytes before/MLO
35416 bytes after/MLO
With this mentioned commit, MLO stops booting on SDP4430 as only 32K
is accessible for non-secure (bootloader) s/w on GP devices and the size
increase to 56K fails boot.
On the latest u-boot commit e7be18225fbea76d1f0034b224f0d1e60f07cfcf,
MLO is now at size 35592 bytes, However, I2C is not necessary for SPL
to function as we use SR_I2C for controlling the PMIC.
Disabling I2C reduces MLO to 32224 bytes which allows
OMAP4 GP platform to boot up.
Since this is common for all OMAP4 platforms, remove the need for I2C
for SPL builds in the common config.
