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).

Add support for serial console into the i.MX23/i.MX28 SPL. A full,

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

arm: mx5: Fix memory slowness on M53EVK
Fix memory access slowness on i.MX53 M53EVK board. Let us inspect the
issue: First of all, the i.MX53 CPU has two memory banks mapped at
0x7000_0000 and 0xb000_0000 and each of those can hold up to 1GiB of
DRAM memory. Notice that the memory area is not continuous. On M53EVK,
each of the banks contain 512MiB of DRAM, which makes a total of 1GiB
of memory available to the system.
The problem is how the relocation of U-Boot is treated on i.MX53 . The
U-Boot is placed at the ((start of first DRAM partition) + (gd->ram_size)) .
This in turn poses a problem, since in our case, the gd->ram_size is 1GiB,
the first DRAM bank starts at 0x7000_0000 and contains 512MiB of memory.
Thus, with this algorithm, U-Boot is placed at offset:
0x7000_0000 + 1GiB - sizeof(u-boot and some small margin)
This is past the DRAM available in the first bank on M53EVK, but is still
within the address range of the first DRAM bank. Because of the memory
wrap-around, the data can still be read and written to this area, but the
access is much slower.
There were two ideas how to solve this problem, first was to map both of
the available DRAM chunks next to one another by using MMU, second was to
define CONFIG_VERY_BIG_RAM and CONFIG_MAX_MEM_MAPPED to size of the memory
in the first DRAM bank. We choose the later because it turns out the former
is not applicable afterall. The former cannot be used in case Linux kernel
was loaded into the second DRAM bank area, which would be remapped and one
would try booting the kernel, since at some point before the kernel is started,
the MMU would be turned off, which would destroy the mapping and hang the
system.

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.

the driver was implemented based on the U-Boot Asix driver with
additional information gathered from the Moschip Linux driver,
development was done on "Delock 61147" and "Logilink UA0025C" dongles

fw_env: correct writes to devices with small erase blocks
Some NOR flash devices have a small erase block size. For example, the
Micron N25Q512 can erase in 4K blocks. These devices expose a bug in
fw_env.c where flash_write_buf() incorrectly calculates bytes written
and attempts to write past the environment sectors. Luckily, a range
check prevents any real damage, but this does cause fw_setenv to fail
with an error.
This change corrects the write length calculation.
The bug was introduced with commit 56086921 from 2008 and only affects
configurations where the erase block size is smaller than the total
environment data size.

fw_env: calculate default number of env sectors
The assumed number of environment sectors (always 1) leads to an
incorrect top_of_range calculation in fw.env.c when a flash device has
an erase block size smaller than the environment data size (number of
environment sectors > 1).
This change updates the default number of environment sectors to at
least cover the size of the environment.
Also corrected a false statement about the number of sectors column in
fw_env.config.

arm: am335x: DXR2: Move unconditional LAN9303 reset into command
The switch HW reset results in a disconnection of the switch port daisy-
chain for a few seconds. This is not desired in the normal field use
case. So lets remove this switch reset from the normal bootup sequence
and move it into a board specific command. This way it can be executed
in the development environment when really needed.

Patch a7e36fc9 (mtd: nand: omap: remove unused #defines from common
omap_gpmc.h) removed some MTD related defines. Including
GPMC_NAND_ECC_LP_x8_LAYOUT. But this define is also needed for the
memory controller configuration (only the x8 defines are needed,
the x16 defines are the default). Without it the NAND subsystem is
not configured correctly and booting into U-Boot does not work.

am335x_evm: Remove SPI SPL from NOR support target
When using the am335x_evm_nor target one is generally expecting to be
used in an environment when you want to program the NOR and not a
"deployment" type target. In addition this only supports the Beaglebone
White with the memory cape and NOR module installed, which precludes the
presence of SPI flash. Drop SPI as we were getting close to the binary
limit in some cases and slightly over with other toolchains.

drivers/spi/omap3: Bug fix of premature write transfer completion
The logic determining SPI "write" transfer completion was faulty. At
certain conditions (e.g. slow SPI clock freq) the transfers were
interrupted before completion. Both EOT and TXS flags of channel
status registeer shall be checked to ensure that all data was
transferred. Tested on AM3359 chip.

am33xx: Rework #ifdef's around s_init for clarity
The s_init function is only called on SPL or XIP cases, so lets only
build it for them. This makes the #if logic within the function a bit
clearer as to when we are or are not calling things, and makes it easier
to see that for example preloader_console_init isn't ever called in the
non-XIP full U-Boot case.
