I'm trying to add support for frame buffer to my au1100 based board but I'm a bit confused where I can allocate the frame buffer memory.
General rule: it's goot to allocate it at the upper end of memory, as we can then pass it unchanged to Linux. See how this is done in other architectures.
Looking at "lib_mips/board.c" I see:
...
/* We can reserve some RAM "on top" here. */
This is the right place.
/* round down to next 4 kB limit. */
...
Is that sane?
Maybe sane, but IMHO not optimal.
