* Added an u8500 board specific ld script. Reserve space for .data
backup.
* Make a backup copy of initialised data (.data section). If restarted,
copy the backup data back to .data.
* Create crashkernel env variable dynamically, since it depends on
U-Boot start address. For dumping U-Boot itself is used as
crashkernel.
* Set preboot environment variable to checkcrash command, if
data_init_flag > 0, i.e. we were restarted e.g. by kexec.
* Added crashkernel parameter to common bootargs.
Decreased environment and pool sizes.
* Changed link address of U-Boot: moved it 32 K up for kdump info to
0x05608000
* Added "checkcrash" command
This command checks if there is a pending crash dump
and writes it to a file on SD/MMC.
