This allows to first read the IVM content (earlier in the boot sequence)
and define the ethaddr env variable thanks to the ivm_read_eepromi().
Later, the IVM content can be parsed and used to define some hush
variables, when the hush subsystem is available thanks to
ivm_analyze_eeprom().
To avoid the HW read to happen twice, the buffer passed to
ivm_read_eeprom() has to be reused by ivm_analyze_eeprom (and thus
allocated before calling ivm_read_eeprom()).

This function can fail if the device tree runs out of space. Rather than
silently booting with an incomplete device tree, allow the failure to be
detected.
Unfortunately this involves changing a lot of places in the code. I have
not changed behvaiour to return an error where one is not currently
returned, to avoid unexpected breakage.
Eventually it would be nice to allow boards to register functions to be
called to update the device tree. This would avoid all the many functions
to do this. However it's not clear yet if this should be done using driver

Such pin should theoretically be handled by the PCIe subsystem

Add set_fdthigh subcommand to "subbootcmds" (release) so to set "fdt_high"
This is necessary on Kirkwood so that the FDT does not get relocated
above the memory limit that the kernel cannot access
(that is the memory part reserved for the switch).
This was tested on NUSA1, where it is necessary, and on ETER1, where it
doesn't seem to hurt.
We want the scripts to also work with older versions of u-boot, where:
a) set_fdthigh is not defined (will be default env for newer u-boots)
b) the fdt will not be available
For this reason, we use "set_fdthigh" to tell whether we are running
a newer (FDT-aware) u-boot or not.
So if "set_fdthigh" runs successfully or arch != arm we try loading
the fdt; otherwise we proceed normally.
Notice how, contrary to release mode, set_fdthigh will _not_ be part of
subbootcmds for develop and ramfs, but will be executed as part of
"tftpfdt".
Since this is only needed for kirkwood cards, and it prevents the kernel
from booting on QorIQ (though it seemed to work on ETER1), we change
its definition in the default env for powerpc so that the value is only
set on ARM.

This patch introduces the support for Keymile's kmp204x reference
design. This design is based on Freescale's P2040/P2041 SoC.
The peripherals used by this design are:
- DDR3 RAM with SPD support
- SPI NOR Flash as boot medium
- NAND Flash
- 2 PCIe busses (hosts 1 and 3)
- 3 FMAN Ethernet devices (FMAN1 DTSEC1/2/5)
- 3 Local Bus windows, with one dedicated to the QRIO reset/power mgmt
FPGA
- 2 HW I2C busses
- last but not least, the mandatory serial port
The board/keymile/kmp204x code is mostly based on Freescale's P2041rdb
support and was changed according to our design (that means essentially
removing what is not present on the designs and a few adaptations).
There is currently only one prototype board that is based on this design
and this patch also introduces it. The board is called kmlion1.

This patch adds SDRAM detection feature to km82xx boards.
To enable this feature, define CONFIG_SYS_SDRAM_LIST as the initializer
for an array of struct sdram_conf_s.
These structs will expose the bitfields within registers PSDMR and OR1 which
have to be different between configurations; common bitfields will be
defined, as usual, within CONFIG_SYS_PSDMR and CONFIG_SYS_OR1.
If CONFIG_SYS_SDRAM_LIST is not defined, then the usual behavior is retained.

These functions tried to access two static tables before relocation
(board_early_init_f is executed before relocation). But these static
tables lie in the bss section which is not valid before relocation.
These accesses then overwrote some parts of u-boot binary before it was
relocated. For the kmnusa build, this results in a corrupted important
env variable (bootcmd) but it may be that some other parts of the u-boot
binary are corrupted.
This patch solves this problem by moving all the kw_gpio_* calls to
board_init, which should be early enough in the boot sequence. The only
calls that could not be moved is the one for the SOFT (bitbang) I2C, and
they have been replaced by a direct access to the GPIO dataout Control
register to set the two GPIOs as output.

Add a function to read the dip_switch on kmcoge5un. If the
switch is set the actual_bank is set to 0 and this SW is

The PCIe FPGAs now have to support 2 resets: one for the non traffic
affecting part (PCIe) and one for the traffic affecting part.
When the FPGA is not reconfigured, we only reset the PCIe part.

In order to be able to perform board resets without interrupting the
traffic, the configuration of an already properly configured FPGA is
skipped.
This is because some PCIe FPGAs embed some other function that must
continue to work over reset.
It is then the responsibility of the application to trigger a
reconfiguration when needed. This is done by lowering the FPGA_INIT_B
pin for delaying the configuration to u-boot @ next reboot, and then
lower the FPGA_PROGRAM_B signal.

This adds a first support of the FPGA download for a PCIe FPGA based
on the BOCO2 CPLD.
This takes place in 3 steps, all done accessing the SPICTRL reg of the
BOCO2:
1) start the FPGA config with an access to the FPGA_PROG bit
2) later in the boot sequence, wait for the FPGA_DONE bit to toggle to 1
for the end of the FPGA configuration (with a timeout)
3) reset the FPGA
4) finally remove the access to its config EEPROM from the FPGA so that
the CPU can update the FPGA configuration when the kernel is running
The boards with a PCIe FPGA but without BOCO2 still are supported.
The config option name is CONFIG_KM_FPGA_CONFIG

The additional headerfile is unneeded here, we can use the generic
km_kirkwood.h instead. And we can use the better config option
KM_PIGGY4_88E6061 for the specific features for boards with this
design in km_arm.c.

For u-boot this board is similar to mgcoge3un. But some differences
are present. We have a different SDRAM on it and therefore a new
SDRAM config file. Additionaly this board has a direct MAC/MAC
connection from the kirkwood to a marvell simple switch without a
phy inbetween, this needs a new configuration for the mvgbe driver.

This board is similar to portl2, but it has the u-boot environment
in a SPI NOR flash and not in an i2c eeprom like portl2 have.
Some other details:
- IVM EEPROM is at adress: pca9547:70:9
- PCI is enabled
- PIGGY4 is connected via MV88E6352 simple switch. There is no phy
between the simple switch and the kirkwood.

We overwrite these weak functions from the kirkwood spi code to
use our own method to be able to switch between the SPI NOR and
the NAND flash. This is needed e.g. to update the u-boot. The former
command do_spi_toggle can therefore be removed. And the usage of
this command is removed from the u-boot update command in the
u-boot environment.
