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.

7b2268b88f arm/km: enable FDT for km_kirwkood
This consists of:
a) Defining the addresses, enabling fdtsupport [arm]
b) Defining "cramfsloadfdt"  [arm,powerpc => common]
c) Adding the FDT address to bootm [arm,powerpc => common]
d) Defining "tftpfdt" in ramfs-,develop- [arm,powerpc >= common]

This should work with 3.10 kernels, whether loaded through TFTP
(with rootfs either through NFS or TFTP-ramfs) or from the NAND.

The machid was left unchanged, this should keep compatibility with both
older and newer kernels.

3cd534e455 ARM: bcm2835: config.mk isn't needed
The entries in config.mk were needed so that U-Boot could be built
with an old version of the Raspberry Pi Foundation's toolchain. Without
them, the build would error out with:

...-ld: error: .../libgcc.a(_bswapsi2.o) uses VFP register arguments,
u-boot does not

However, none of the 3 toolchains in the latest version of their
tools.git, nor the Ubuntu/Linaro ARM compilers in at least Ubuntu Quantal
or Saucy, need these options set in order to compile a working U-Boot.
Hence, remove the options for simplicity.

bccaa476f6 ARM: rpi_b: set $fdtfile in default environment
U-Boot names the Raspberry Pi board rpi_b. This means that the common
expression for DTB filename ${soc}-${board}.dtb expands to
bcm2835-rpi_b.dtb. However, the DTB generated by the Linux kernel is
bcm2835-rpi-b.dtb. Set $fdtfile in U-Boot's environment so that scripts
look for the correct DTB filename.

An alternative would be to rename the U-Boot board to rpi-b. However,
that change would be far more invasive, and end up affecting users (i.e
they'd have to change their U-Boot build commands).
