H A Dstart.S55e2b4d4e5dd179d748dca9f8c44585b7319f2e2 Fri Oct 09 12:09:17 UTC 2015 Thomas Chou <thomas@wytron.com.tw> nios2: set default cache configuration in start.S

Set default icache and dcache configuration for start.S.

We want to remove the CONFIG_SYS_{I,D}CACHE_SIZE...
configuration macros. As we are just barely starting from
reset, there is no luxury of device tree.

We will set some maximum cache configuration so that it will
work for most configurations. This is used only in this
start.S. The speed penalty is only once here.

After start up, during board initialization, cpu information
will be extracted from device tree. Then cache flush operations
will have correct cache configurations.
