TQM85xx: Change memory map to support Flash memory > 128 MiB
Some TQM85xx boards could be equipped with up to 1 GiB (NOR) Flash
memory. The current memory map only supports up to 128 MiB Flash.
This patch adds the configuration option CONFIG_TQM_BIGFLASH. If
set, up to 1 GiB flash is supported. To achieve this, the memory
map has to be adjusted in great parts (for example the CCSRBAR is
moved from 0xE0000000 to 0xA0000000).
If you want to boot Linux with CONFIG_TQM_BIGFLASH set, the new
memory map also has to be considered in the kernel (changed
CCSRBAR address, changed PCI IO base address, ...). Please use
an appropriate Flat Device Tree blob (tqm8548.dtb).
