develop mode
Search for the kernel and DTBs in a folder named PRODUCTNAME (found in the IVM)
at the TFTP server instead of the u-boot boardname.

When loading the dtb file via tftp we should load the one which matches
boardId and hwKey and not a common one for the boardname. We have boards
were different hwKeys are used and then we may load an incorrect dtb
file. If no fdt_bid_kwkey.dtb file is not a fallback to boardname.dtb is used.

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 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.

Replace uImage with ${uimage}.
If uimage is not set, default it to uImage.

Calucations of PRAM needs to take into account the 'rootfssize'.
Memory available to the linux kernel 'mem=' is in all cases set to the total
memory size minus the pram size.

The debug environment which is stored in textfiles in the
scripts directory was reworked. Two usecase are now present
which can be executed simply from the default environment:
run develop: this configures the environment to setup the
rootfs via nfs
run ramfs: this configures the environment to setup the
rootfs in ram
Each architecture now has a "arch" variable which is used
to load the architecture specific debug scripts and to set
the rootpath for NFS.
