1a9df13d5b 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).

9926eb31b7 arm: mxs: Add serial console support into SPL
Add support for serial console into the i.MX23/i.MX28 SPL. A full,
uncrippled serial console support comes very helpful when debugging
various spectacular hardware bringup issues early in the process.
Because we do not use SPL framework, but have our own minimalistic
SPL, which is compatible with the i.MX23/i.MX28 BootROM, we do not
use preloader_console_init(), but instead use a similar function to
start the console. Nonetheless, to avoid blowing up the size of the
SPL binary, this support is enabled only if CONFIG_SPL_SERIAL_SUPPORT
is defined, which is disabled by default.

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.

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.

9e4140329e kbuild: change out-of-tree build
This commit changes the working directory
where the build process occurs.

Before this commit, build process occurred under the source
tree for both in-tree and out-of-tree build.

That's why we needed to add $(obj) prefix to all generated
files in makefiles like follows:
  $(obj)u-boot.bin:  $(obj)u-boot

Here, $(obj) is empty for in-tree build, whereas it points
to the output directory for out-of-tree build.

And our old build system changes the current working directory
with "make -C <sub-dir>" syntax when descending into the
sub-directories.

On the other hand, Kbuild uses a different idea
to handle out-of-tree build and directory descending.

The build process of Kbuild always occurs under the output tree.
When "O=dir/to/store/output/files" is given, the build system
changes the current working directory to that directory and
restarts the make.

Kbuild uses "make -f $(srctree)/scripts/Makefile.build obj=<sub-dir>"
syntax for descending into sub-directories.
(We can write it like "make $(obj)=<sub-dir>" with a shorthand.)
This means the current working directory is always the top
of the output directory.

Makefile conflicts are due to additions/removals of

the list of object files in the main branch version.
This also applies to two files which are not listed
as conflicting but had to be modified:

	board/compulab/common/Makefile
	board/udoo/Makefile

include/configs/omap4_common.h conflicts are due to
the OMAP4 conversion to ti_armv7_common.h on the ARM
side, and CONFIG_SYS_HZ removal on the main side.
Resolution is to convert as this icludes removal of
CONFIG_SYS_HZ.

include/configs/pdnb3.h is due to a removal on ARM side.
Trivial resolution is to remove the file.

Note: 'git show' will also list two files just because

77b0e2239a ARM: mxs: Setup stack in JTAG mode
In case the MX23/MX28 is switched into JTAG mode via the BootMode select
switches, the BootROM bypasses the CPU core registers initialization.
This in turn means that the Stack Pointer (SP) register is not set as
it is in every other mode of operation, but instead is only zeroed out.

To prevent U-Boot SPL from crashing in this obscure JTAG mode, configure
the SP to point at the CONFIG_SYS_INIT_SP_ADDR if the SP is zeroed out.

Note that in case the SP is already configured, we must preserve that exact
SP value and must not modify it. This is important since in every other mode
but the JTAG mode, the SPL returns into the BootROM and BootROM in turn loads
U-Boot itself. If the SP were to be corrupted, the BootROM won't be able to
continue it's operation after returned from SPL and the system would crash.

Finally, add the JTAG mode switch identifier, so it's not recognised as
Unknown mode.

dd3ecf020e arm: mx23: Fix VDDMEM misconfiguration
The VDDMEM ramped up in very weird way as it was horribly misconfigured.
Instead of setting up VDDMEM in one swipe, let it rise slowly the same
way as VDDD and VDDA in spl_power_init.c and then only clear ILIMIT before
memory gets inited. This makes sure the VDDMEM rises sanely, not jumps up
and down as it did till now.

The VDDMEM prior to this change did this:
     2V0____   .--------2V5
       |    `--'
 0V____|

The VDDMEM now does this:
    2V0_____,-----------2V5
      /
 0V__|

Moreover, VDDIO on MX23 uses 25mV steps while MX28 uses 50mV steps,

b33426caf6 mxs: spl_mem_init: Align DDR2 init with FSL bootlets source
Currently the following kernel hang happens when loading a 2.6.35 kernel from
Freeescale on a mx28evk board:

RPC: Registered tcp transport module.
RPC: Registered tcp NFSv4.1 backchannel transport module.
Bus freq driver module loaded
IMX usb wakeup probe
usb h1 wakeup device is registered
mxs_cpu_init: cpufreq init finished
...

Loading the same kernel using the bootlets from the imx-bootlets-src-10.12.01
package, the hang does not occur.

Comparing the DDR2 initialization from the bootlets code against the U-boot
one, we can notice some mismatches, and after applying the same initialization
into U-boot the 2.6.35 kernel can boot normally.

Also tested with 'mtest' command, which runs succesfully.

3430e0bd2a mxs: mmc: spi: dma: Better wrap the MXS differences
This patch streamlines the differences between the MX23 and MX28 by
implementing a few helper functions to handle different DMA channel
mapping, different clock domain for SSP block and fixes a few minor
bugs.

First of all, the DMA channel mapping is now fixed in dma.h by defining
the actual channel map for both MX23 and MX28. Thus, MX23 now does no
longer use MX28 channel map which was wrong. Also, there is a fix for
MX28 DMA channel map, where the last four channels were incorrect.

Next, because correct DMA channel map is in place, the mxs_dma_init_channel()
call now bases the channel ID starting from SSP port #0. This removes the
need for DMA channel offset being added and cleans up the code. For the
same reason, the SSP0 offset can now be used in mxs_dma_desc_append(), thus
no need to adjust dma channel number in the driver either.

Lastly, the SSP clock ID is now retrieved by calling mxs_ssp_clock_by_bus()
which handles the fact that MX23 has shared SSP clock for both ports, while
MX28 has per-port SSP clock.

Finally, the mxs_ssp_bus_id_valid() pulls out two implementations of the
same functionality from MMC and SPI driver into common code.

5c2f444c9b mxs: Reset the EMI block on mx23
The real reason for memory instability was the fact that the EMI block
was gated and not reset throughout the boards' operation. This patch
resets the EMI block properly while also reverts the memory voltage bump.
The memory stability issues were caused by the EMI not being reset properly
and thus there is no longer need to run the memory at higher voltage than
it ought to run at.

This partly reverts 8303ed128a .
