2014-02-13arm/km: define fdt_high env variable and allow backwards compatibilityGerlando Falauto
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.

2014-02-13arm/km: enable FDT for km_kirwkoodGerlando Falauto
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.

'actual_bank' is not used anymore, instead boot_bank is used. Signed-off-by: Andreas Huber <andreas.huber@keymile.com>
2013-02-15km/scripts: replace hardcoded uImageAndreas Huber
Replace uImage with ${uimage}. If uimage is not set, default it to uImage. Signed-off-by: Andreas Huber <andreas.huber@keymile.com> Signed-off-by: Holger Brunck <holger.brunck@keymile.com>
2011-10-22km/common: fix ramfs development targetAndreas Huber
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.

2011-07-27km/common: simplify debug environmentHolger Brunck
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.
