People who write (or scripts that auto-generate) extlinux.conf don't
want to know about HW-specific information such as FDT filenames. Create
a new extlinux.conf tag "fdtdir" that specifies only the directory where
FDT files are located, and defer all knowledge of the filename to U-Boot.
The algorithm implemented is:
==========
if $fdt_addr_r is set:
if "fdt" tag was specified in extlinux.conf:
load the FDT from the filename in the tag
else if "fdtdir" tag was specified in extlinux.conf:
if "fdtfile" is set in the environment:
load the FDT from filename in "$fdtfile"
else:
load the FDT from some automatically generated filename
if no FDT file was loaded, and $fdtaddr is set:
# This indicates an FDT packaged with firmware
use the FDT at $fdtaddr
==========
A small part of an example /boot/extlinux.conf might be:
==========
LABEL primary
LINUX zImage
FDTDIR ./
LABEL failsafe
LINUX bkp/zImage
FDTDIR bkp/
==========
... with /boot/tegra20-seaboard.dtb or /boot/bkp/tegra20-seaboard.dtb
being loaded by the sysboot/pxe code.

The specification for extlinux.conf[1] states that "fdt" is an alias for
"devicetree". To date, U-Boot only implements "fdt". Rectify that.

The PEXHC PCIe configuration mechanism ensures that the FPGA get
configured at power-up. Since all the PCIe devices should be configured
when the kernel start, u-boot has to take care that the FPGA gets
configured also in other reset scenarios, mostly because of possible
configuration change.
The used mechanism is taken from the km_kirkwood design and adapted to
the kmp204x case (slightly different HW and PCIe configuration).

This define can be used if the ubi boot partition (defined for all

This is the case for the kmp204x boards since u-boot does not support
NAND Flash subpage accesses on this platform, an additionnal argument
that defines the VID offstet must be given to the kernel.

This patch adds support for using some GPIOs that are connected to the
I2C bus to force the bus lines state and perform some bus deblocking
sequences.
The KM common deblocking algorithm from board/keymile/common/common.c is
used. The GPIO lines used for deblocking the I2C bus are some external
GPIOs provided by the QRIO CPLD:
- SCL = GPIOA_20
- SDA = GPIOA_21
The QRIO GPIOs act in an open-drain-like manner, for 0 the line is
driven low and for 1 the GPIO is set as input and the line gets
pulled-up.

This is only required for "PIC" relocation and doesn't apply to modern
"PIE" relocation which does data relocation as well as code.
"init_sequence_r" is just an array that consists of compile-time
adresses of init functions. Since this is basically an array of integers
(pointers to "void" to be more precise) it won't be modified during
relocation - it will be just copied to new location as it is.
As a consequence on execution after relocation "initcall_run_list" will
be jumping to pre-relocation addresses. As long as we don't overwrite
pre-relocation memory area init calls are executed correctly. But still
it is dangerous because after relocation we don't expect initially used
memory to stay untouched.
