2bbcccf552 ARM: mxs: Add OCOTP driver
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.

53e6b14e03 arm: mxs: Add support for generating signed BootStream
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).

9c2c8a3129 arm: mxs: Adjust the load address of U-Boot and SPL for HAB
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.

4642e0022b Kbuild: allow building tools without board configuration
Prior to Kbuild, U-Boot could build under tools/ directory
withour configuring for a specific board.

That feature was lost when switching to Kbuild.

This patch revives it again by adding a make target "tools-only".

Usage:
  $ make tools-only

Neither board configuration nor cross compiler are required to

5a449d75bc kbuild: create a build directory automatically for out-of-tree build
Prior to Kbuild, the build system created a build directory,
when it did not exist, for out-of-tree build.

This feature was dropped when we switched to Kbuild
because many of lines in makefiles were copied from Linux Kernel.
(In Linux Kernel, we have to create a build directory by ourselves
before starting build.)

That feature seems worth reviving for less typing
even if our code and Linux Kernel diverge.

254d68b601 kbuild: move asm-offsets.c from SoC directory to arch/$(ARCH)/lib
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
arch/{arm,nds32}/lib/asm-offsets.c.

93bfd61677 mmc: Split mmc struct, rework mmc initialization (v2)
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.

on nand flash using ubi, after the download of the new image into

the medium. With current u-boot version dfu-util may show:

Starting download: [##################################################] finished!
state(7) = dfuMANIFEST, status(0) = No error condition is present
unable to read DFU status

as get_status is not answered while erasing sectors, if erasing
needs some time.

So do the following changes to prevent this:

- introduce dfuManifest state
  According to dfu specification
  ( http://www.usb.org/developers/devclass_docs/usbdfu10.pdf ) section 7:
  "the device enters the dfuMANIFEST-SYNC state and awaits the solicitation
   of the status report by the host. Upon receipt of the anticipated
   DFU_GETSTATUS, the device enters the dfuMANIFEST state, where it
   completes its reprogramming operations."

- when stepping into dfuManifest state, sending a PollTimeout
  DFU_MANIFEST_POLL_TIMEOUT in ms, to the host, so the host
  (dfu-util) waits the PollTimeout before sending a get_status again.

the implementation depends solely on components internal to U-Boot.

To allow building against the internal AES library, the library did
need minor adjustments to not include U-Boot's headers which are not
wanted to be included and define missing types.

a4223b746d env: Implement support for encrypting environment
Add function which allows encrypting the whole environment block with
AES-128-CBC. The key for the environment is retrieved by
env_aes_cbc_get_key() function, which must be implemented on a per-board
basis.

7ce1526ed2 env: Add env_export() wrapper
Implement env_export() wrapper, so that all implementers of saveenv() don't
have to call hexport_r(), crc32() etc. sequence . This trims down a bit of
code duplication.

6e7b9f4fa0 aes: Move the AES-128-CBC encryption function to common code
Move the AES-128-CBC encryption function implemented in
tegra20-common/crypto.c into lib/aes.c . This is well re-usable common
code. Moreover, clean the code up a bit and fix the kerneldoc-style
annotations.
