U-Boot SPL for mvebu platform is not compiled as position independent.
Therefore it is required to instruct BootROM to load U-Boot SPL at the
correct address. Loading of kwbimage binary code at specific address can be
now achieved by the new LOAD_ADDRESS token as part of BINARY command in
kwbimage config file.
Update mvebu Makefile to put value of $(CONFIG_SPL_TEXT_BASE) into
LOAD_ADDRESS token when generating kwbimage.cfg from kwbimage.cfg.in.
It is required to update regex for sed to find replacement tokens at any
position on a line in kwbimage config file and not only at the beginning of
the line. This is because LOAD_ADDRESS is specified at the end of line
containing the BINARY command.
It looks like all Armada boards set CONFIG_SPL_TEXT_BASE to value
0x40004030 or 0x40000030. Why this value? It is because main kwbimage
header is at address 0x40004030 or 0x40000000 and it is 32 bytes long.
After the main header there is the binary header, which consist of 1 byte
for type, 3 bytes for size, 1 byte for number of arguments, 3 reserved
bytes and then 4 bytes for each argument. After these arguments comes the
executable code.
So arguments start at address 0x40004028 or 0x40000028. Before commit
