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.
