6ec1b75358 dm: i2c: Add an I2C EEPROM simulator
To enable testing of I2C, add a simple I2C EEPROM simulator for sandbox.
It supports reading and writing from a small data store.

63656b762e dm: i2c: Implement driver model support in the i2c command
The concept of a 'current bus' is now implemented in the command line
rather than in the uclass. Also the address length does not need to
be specified with each command - really we should consider dropping
this from most commands but it works OK for now.

c6202d857e dm: i2c: Add a uclass for I2C
The uclass implements the same operations as the current I2C framework but
makes some changes to make it fit driver model better:

- Remove the chip address from API calls
- Remove the address length from API calls
- Remove concept of 'current' I2C bus
- Drop all existing init functions

59345b1f0f lib: errno: introduce errno_str(): returns errno related message
The functions error's numbers are standarized - but the error
messages are not.

The errors are often handled with unclear error messages,
so why not use an errno standarized messages.

Advantages:
- This could decrease the binary size.
- Appended with a detailed information,
  the error message will be clear.

This commit introduces new function:
- const char *errno_to_str(int errno)

The functions returns a pointer to the errno corresponding text message:
- if errno is null or positive number - a pointer to "Success" message
- if errno is negative - a pointer to errno related message

7a3620b246 ARM: UniPhier: detect the number of flash banks at run-time
Some UniPhier boards are equipped with an expansion slot that
some optional SRAM/NOR-flash cards can be attached to.  So, run-time
detection of the number of flash banks would be more user-friendly.

Until this commit, UniPhier boards have achieved this by (ab)using
board_flash_wp_on() because the boot failed if flash_size got zero.
Fortunately, this problem was solved by commit 70879a9256 (flash:
do not fail even if flash_size is zero).

Now it is possible to throw away such a tricky workaround.  This
commit also enables CONFIG_SYS_MAX_FLASH_BANKS_DETECT for further
refactoring.

48aead71c1 fdt: Allow non-FDT kernels to boot when CONFIG_OF_LIBFDT is defined
The boot commands - bootz/bootm mandate a third argument which is the
address to the FDT blob. In cases where this argument is not specified,
boot fails with a message indicating a missing FDT.

This causes non-FDT kernels to fail to boot. This patch allows both FDT
and non-FDT kernels to boot by making the third parameter to the bootm/bootz
optional.

e19db555b4 Kbuild: introduce Makefile in arch/$ARCH/
Introduce a Makefile under arch/$ARCH/ and include it in the
top Makefile (similar to Linux kernel). This allows further
refactoringi like moving architecture-specific code out of global
makefiles, deprecating config variables (CPU, CPUDIR, SOC) or
deprecating arch/$ARCH/config.mk.

In contrary to Linux kernel, U-Boot defines the ARCH variable by
Kconfig, thus the arch Makefile can only included conditionally
after the top config.mk.
