Add:
- introduce "bootrunner" environment variable
This allows to execute consecutive different commands
specified in the list "subbootcmd". If one command fails
the command serie will stop.
- introduce environment variable "develop", "ramfs" and "release"
Each variable is one way to boot our linux. "develop" is for
development purpose and boots the SW via NFS. "release" is for
booting the linux image from flash, "ramfs" allows to load an SW
image via tftp into ram and executes from there
- introduce "addmem" variable, this command adds the used memory
for linux to the bootargs
- introduce "addvar" variable, this command adress for the /var
directory to the kernel command line
- introduce "setramfspram" and "setrootfsaddr" these calculation
were done if "ramfs" was used (only for debugging)
- introduce "tftpramfs" used for "ramfs" to load the image into
RAM (only for debugging)
Remove unneeded stuff:
- CONFIG_IO_MUXING is obsolete for keymile boards
- CONFIG_KM_DEF_ENV_PRIVATE is also obsolete
- define CONFIG_SYS_TEXT_BASE in board configs only
