In the current u-boot, the device pin multiplexing and clock
initialisation needs to be early during the boot process and before

because this is not being done early enough. Therefore, add a s_init()

Also fix the stack pointer so that it is pointing to the end of the

We make these two functions take a size_t pointer to how much space
was used on NAND to read or write the buffer (when reads/writes happen)
so that bad blocks can be accounted for. We also make them take an
loff_t limit on how much data can be read or written. This means that
we can now catch the case of when writing to a partition would exceed
the partition size due to bad blocks. To do this we also need to make
check_skip_len count not just complete blocks used but partial ones as
well. All callers of nand_(read|write)_skip_bad are adjusted to call
these with the most sensible limits available.
The changes were started by Pantelis and finished by Tom.

Previously we didn't support upload/download larger than available
memory. This is pretty bad when you have to update your root filesystem
for example.
This patch removes that limitation (and the crashes when you transfered
any file larger than 4MB) by making raw image writes be done in chunks
and making file maximum size be configurable.
The sequence number is a 16 bit counter; make sure we handle rollover
correctly. This fixes the wrong transfers for large (> 256MB) images.
Also utilize a variable to handle initialization, so that we don't rely
on just the counter sent by the host.

For production systems it is better to use script images since
they are protected by checksums and carry valuable information
like name and timestamp. Also, you can't validate the content
passed to env import.
But for development, it is easier to use the env import command and
plain text files instead of script-images.
Since both OMAP5evm/uevm boards are used primarily for development,
we allow U-Boot to load env var from a text file in case that an
boot.scr script-image is not present.
The variable uenvcmd (if existent) will be executed (using run) after
uEnv.txt was loaded. If uenvcmd doesn't exist the default boot sequence
will be started.

The omap2420-h4 board is using a RAM based address as the linker

the default linker location for code to be in NOR flash. Please note
that OMAP maps the NOR flash to address 0x08000000 by default and so
use this as the default address for the NOR flash.
Also remove legacy code that attempts to calculate where in flash the
sdata structure, that holds the memory interface configuration data,
is located. By changing the default linker location for code to flash
this is no longer necessary.

Maximum bus width supported by some i.MX6 boards is not 8bit like

they agree to communicate on 8bit interface while some boards support only 4bit interface.
Due to this reason the mmc 8bit default mode fails on these boards. To rectify this,
define maximum bus width supported by these boards (4bit). If max_bus_width is not
defined, it is 0 by default and 8bit width support will be enabled in host
capabilities otherwise host capabilities are modified accordingly.

This commit is based on that patch from aaron.williams@caviumnetworks.com
with same commit title. pulled the same code changes into current u-boot tree.
http://patchwork.ozlabs.org/patch/140863/http://lists.denx.de/pipermail/u-boot/2011-April/089606.html
This patch corrects the addresses used when working with Spansion/AMD FLASH chips.
Addressing for 8 and 16 bits is almost identical except in the 16-bit case the
LSB of the address is always 0. The confusion arose because the addresses
in the datasheet for 16-bit mode are word addresses but this code assumed it was
byte addresses.
I have only been able to test this on our Octeon boards which use either an 8-bit
or 16-bit bus. I have not tested the case where there's an 8-bit part on a 16-bit
bus.
This patch also adds some delays as suggested by Spansion.
If a part can be both 8 and 16-bits, it forces it to work in 8-bit mode if an
8-bit bus is detected.
Apart from the pulled changes, fixed few minor code cleanups and tested
on 256M29EW, 512M29EW flashes.

When running this command the menu will be assembled as defined

When loading a Freescale 2.6.35 on a mx28evk the following issue is seen:
sgtl5000_hw_read: read reg error : Reg 0x00
Device with ID register 0 is not a SGTL5000
Disabling CONFIG_CMD_I2C makes the sgtl5000 probe to succeed.

We create a separate header file for link symbols defined by the link
scripts. It is helpful to have these all in one place and try to
make them common across architectures. Since Linux already has a similar
file, we bring this in even though many of the symbols there are not
relevant to us.
Each architecture has its own asm/sections.h where symbols specifc to
that architecture can be added. For now everything except AVR32 just
includes the generic header.
One change is needed in arch/avr32/lib/board.c to make this conversion
work.

Tegra20 has a Cortex A9 r1p1, and Tegra30 has a Cortex A9 r2p9. As such,
some CPU errata exist, and must be worked around.
These must be worked around in the bootloader, since in general, the
kernel (especially a multi-platform kernel) needs to support being
launched in non-secure mode (normal world), and hence may not be able
to write to the CP15 register to enable these workarounds.

Refactor linker-generated array code so that symbols
which were previously linker-generated are now compiler-
generated. This causes relocation records of type
R_ARM_ABS32 to become R_ARM_RELATIVE, which makes
code which uses LGA able to run before relocation as
well as after.
Note: this affects more than ARM targets, as linker-
lists span possibly all target architectures, notably
PowerPC.

The "mtest" command is of little practical use (if any), and
experience has shown that a large number of board configurations
define useless or even dangerous start and end addresses. If not even
the board maintainers are able to figure out which memory range can be
reliably tested, how can we expect such from the end users? As this
problem comes up repeatedly, we rather do not enable this command by
default, so only people who know what they are doing will be
confronted with it.
As this changes the user interface, we allow for a grace period
before this change takes effect. For now, we make "mtest"
configurable through the CONFIG_CMD_MEMTEST variable, which is defined
in include/config_cmd_default.h; we also add an entry to
doc/feature-removal-schedule.txt which announces the removal of this
default setting in two releases from now, i. e. with v2013.07.
