0bb95a68fc kirkwood/km_arm: read the IVM eeprom earlier
This allows to define the ethaddr env variable according to the the IVM
content by reading the IVM in misc_init_r.

Later, when HUSH is available the content read earlier is analyzed to
populate some non env variables.

16ac90c7ee KM/IVM: split the IVM reading and parsing in 2 parts
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()).

e895a4b06f fdt: Allow ft_board_setup() to report failure
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
model or with a linker list. This work is left for later.

f38391793f kmp204x: reset the Zarlink clocking chips at power up only
There is the requirement on the chassis's backplane that when the clocks
have been enabled, they then should not disappear.

Resetting the Zarlink clocking chips at unit reset violates this
requirement because the backplane clocks are not supplied during the
reset time.

To avoid this side effect, both the Zarlink clocking chips are reset
only at power up.

93d4334f7f Add board MAINTAINERS files
We have switched to Kconfig and the boards.cfg file is going to
be removed. We have to retrieve the board status and maintainers
information from it.

The MAINTAINERS format as in Linux Kernel would be nice
because we can crib the scripts/get_maintainer.pl script.

After some discussion, we chose to put a MAINTAINERS file under each
board directory, not the top-level one because we want to collect
relevant information for a board into a single place.

TODO:

dd84058d24 kconfig: add board Kconfig and defconfig files
This commit adds:
 - arch/${ARCH}/Kconfig
    provide a menu to select target boards
 - board/${VENDOR}/${BOARD}/Kconfig or board/${BOARD}/Kconfig
    set CONFIG macros to the appropriate values for each board
 - configs/${TARGET_BOARD}_defconfig
    default setting of each board

(This commit was automatically generated by a conversion script
based on boards.cfg)

In Linux Kernel, defconfig files are located under
arch/${ARCH}/configs/ directory.
It works in Linux Kernel since ARCH is always given from the
command line for cross compile.

But in U-Boot, ARCH is not given from the command line.
Which means we cannot know ARCH until the board configuration is done.
That is why all the "*_defconfig" files should be gathered into a
single directory ./configs/.

af47faf650 kmp204x: complete the reset sequence and PRST configuration
This adds the reset support for the following devices that was until
then not implemented:
- BFTIC4
- QSFPs

This also fixes the configuration of the prst behaviour for the other
resets: Only the u-boot and kernel relevant subsystems are taken out of
reset (pcie, ZL30158, and front eth phy).

Most of the prst config move to misc_init_f(), except for the PCIe
related ones that are in pci_init_board and the bftic and ZL30158 ones
that should be done as soon as possible.

Only the behavior of the Hooper reset is changed according to the
documentation as the application is not able to not configure the switch
when it is not reset.

9c134e189a arm/km: introduce kmsugp1 target
KMSUGP1 is from a u-boot perspective (almost) identical to KMNUSA.
The only difference is that the PCIe reset is connected to Kirkwood pin
MPP7_PEX_RST_OUTn, we use a dedicated config flag KM_PCIE_RESET_MPP7.
Such pin should theoretically be handled by the PCIe subsystem
automatically, but this turned out not to be the case.
So simply configure this PIN as a GPIO and issue a pulse manually.

b1c2a7ae32 arm/km: define fdt_high env variable and allow backwards compatibility
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 should work with 3.10 kernels, whether loaded through TFTP

when the kernel start, u-boot has to take care that the FPGA gets

f3e74d0a9f kmp204x: I2C deblocking support
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.

- 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.

99f6249a0e KM: add CONFIG_KM_COMMON_ETH_INIT for km common eth init
This must be defined by a board support file that want to use the
keymile common.c board_eth_init function that requires ethernet_present
to be defined.

Currently all the km architectures use it but the kmp204x architecture
later supported in this series does use another board_eth_init function
and thus does not define it.

0a4f88b98c KM: define CONFIG_SYS_I2C_INIT_BOARD only for concerned board
This must be defined for all the keymile boards that use the common
i2c_abort function that is used to "reset" the I2C bus. These are
currently km82xx and km_arm boards.

The  km83xx boards use other functions and thus do not need this.

This patch removes the CONFIG_SYS_I2C_INIT_BOARD from keymile-common.h
and defines it for km_arm.h and km82xx.h.

port is selected (UEC2, eth1). If the Piggy isn't present, the
Frontport is selected (UEC0, eth0).

The switch reset is connected to a GPIO on the PRIO3 board FPGA (GPIO28)

136846d77f arm/km: remove duplicate code
This patch removes 2 small portions of board specific code that are
duplicated with common ARM code and thus unnecessary. These 2 portions
of code concern the mach id that is given by u-boot to the Linux kernel
to identify the system's MACH.

The first one was the possibility to change the MACH thanks to the
'mach_id' enviroment variable. This is possible thanks to the 'machid'
env variable (see arch/arm/lib/bootm.c:boot_jump_linux()).

The seconde one is the setting of the bi_arch_number. This is already
done in arch/arm/lib/board.c:board_init_f() since km_arm.h does #define
CONFIG_MACH_TYPE.

c471d84808 arm/km: remove calls to kw_gpio_* in board_early_init_f
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.

bcac5b1b2c arm/km: skip FPGA config when already configured
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

This takes place in 3 steps, all done accessing the SPICTRL reg of the

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

phy inbetween, this needs a new configuration for the mvgbe driver.

8170aefc84 arm/km: add kmnusa board support
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.

0c25defccd arm/km: use spi claim bus to switch between SPI and NAND
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.
