4e779ad2e5 gpio: Add support for microblaze xilinx GPIO
Microblaze uses gpio which is connected to the system reset.
Currently gpio subsystem wasn't used for it.

Add gpio driver and change Microblaze reset logic to be done
via gpio subsystem.

There are various configurations which Microblaze can have
that's why gpio_alloc/gpio_alloc_dual(for dual channel)
function has been introduced and gpio can be allocated
dynamically.

Adding several gpios IP is also possible and supported.

For listing gpio configuration please use "gpio status" command

This patch also remove one compilation warning:
microblaze-generic.c: In function 'do_reset':
microblaze-generic.c:38:47: warning: operation on '*1073741824u'
 may be undefined [-Wsequence-point]

1de55ef105 microblaze: usable uart16550 for big endian systems
As a result of the commit 6833260 the uart16550 driver
is broken for Microblaze big endian systems, because of
the missing 3 byte offset. Other than as described, not
all U-Boot BSP will treat properly the 3 byte offset.

This why prefer to mask out the 3 byte offset in general
and setup correct _REG_SIZE value depending on edianess.

1020286ef4 microblaze: Fix bd_info pointer
Patch "Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated value"
(sha1: 25ddd1fb0a)
introduce GENERATED_GBL_DATA_SIZE which is sizeof aligned gd_t
(currently 0x40).
Microblaze configs used 0x40(128) because this place also contained
board info structure which lies on the top of ram.

U-Boot is placed to the top of the ram (for example 0xd7ffffff)
and bd structure was moved out of ram.

This patch is fixing this scheme with GENERATED_BD_INFO_SIZE
which swap global data and board info structures.

For example:
Current: gd 0xd7ffffc0, bd 0xd8000000
Fixed:   gd 0xd7ffffc0, bd 0xd7ffff90

25ddd1fb0a Replace CONFIG_SYS_GBL_DATA_SIZE by auto-generated value
CONFIG_SYS_GBL_DATA_SIZE has always been just a bad workarond for not
being able to use "sizeof(struct global_data)" in assembler files.
Recent experience has shown that manual synchronization is not
reliable enough.  This patch renames CONFIG_SYS_GBL_DATA_SIZE into
GENERATED_GBL_DATA_SIZE which gets automatically generated by the
asm-offsets tool.  In the result, all definitions of this value can be
deleted from the board config files.  We have to make sure that all
files that reference such data include the new <asm-offsets.h> file.

No other changes have been done yet, but it is obvious that similar
changes / simplifications can be done for other, related macro
definitions as well.

14d0a02a16 Rename TEXT_BASE into CONFIG_SYS_TEXT_BASE
The change is currently needed to be able to remove the board
configuration scripting from the top level Makefile and replace it by
a simple, table driven script.

Moving this configuration setting into the "CONFIG_*" name space is
also desirable because it is needed if we ever should move forward to
a Kconfig driven configuration system.

942556a92a mtd: MTD related config header changes (mtdparts command)
By changing the cmd_mtdparts to only use the MTD infrastructure and
not the direct interface to the CFI NOR FLASH driver we now need
to add the MTD infrastructure to all boards using those mtdparts
commands. This patch adds those components:

CONFIG_MTD_DEVICE (for all FLASH types)

plus

CONFIG_FLASH_CFI_MTD (for NOR FLASH)

To all board maintainers: Please test this on your platforms and
report any problems/issues found. Thanks.

68d7d65100 Separate mtdparts command from jffs2
Currently the mtdparts commands are included in the jffs2 command support.
This doesn't make sense anymore since other commands (e.g. UBI) use this
infrastructure as well now. This patch separates the mtdparts commands from
the jffs2 commands making it possible to only select mtdparts when no JFFS2
support is needed.
