Add yet another OCOTP driver for this i.MX family. This time, it's a driver for
the OCOTP variant found in the i.MX23 and i.MX28. This version of OCOTP is too
different from the i.MX6 one that I could not use the mxc_ocotp.c driver without
making it into a big pile of #ifdef . This driver implements the regular fuse
command interface, but due to the IP blocks' limitation, we support only READ
and PROG functions.

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).

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.

desired delay in cycles that the EMIF waits without an access to enter
self-refresh, in this case 8192 cycles. With this, code desiring to
enter self refresh only has to toggle one bit to enable it.

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.

Before this commit, make terminated with an error
where is shouldn't under some condition.
This bug happened when we built a board unsupporting
generic board right after building with generic board.
For example, the following sequence failed.
(harmony uses generic board but microblaze-generic does not
support it)
$ make harmony_config
Configuring for harmony board...
$ make CROSS_COMPILE=arm-linux-gnueabi-
[ Build succeed ]
$ make microblaze-generic_config
Configuring for microblaze-generic board...
$ make CROSS_COMPILE=microblaze-linux-
Makefile:488: *** Your architecture does not support generic board.
Please undefined CONFIG_SYS_GENERIC_BOARD in your board config file. Stop.
We had to do "make clean" before building the microblaze board.
This commit fixes this unconvenience.
Move generic board sanity check to "prepare1" target,
which is run after generation of include/autoconf.mk.

- Generate include/generated/{timestamp.h, version.h}
more simply by using filechk rule.
- Add $(UBOOTRELEASE) variable and re-write u-boot.imx rule
more simply.
- Rename U_BOOT_VERSION in Makefile to UBOOTVERSION
Before this commit, the same variable name, "U_BOOT_VERSION"
was used for two different strings.
One of them was defined in Makefile.
It takes the form like "2014.01-rc1" and used in
makefiles and script files.
The other is defined in include/generated/version.h
It takes the form like "U-Boot 2014.01-rc1-00010-gbe6d426-dirty"
and used in C and Aseembler.
It is confusing when grepping the source tree. So, this commit
renames the former to UBOOTVERSION.
