All,
I am going to modify ecos for Cirrus Logic's edb7312.
I have noticed the difference between 7312 and 7212,
which is 1) on-chip sram: 48K for 7312, 37.5K for
7212; 2) external ram type: sdram for 7312, edo for
7212.
Now, which code sections should I pay attention first?
Are those only in:
...\hal\arm\edb7xxx\v1_3\include
...\hal\arm\edb7xxx\v1_3\include\pkgconf ?

Thx
Peihong Li

Both. Although the stuff in hal_platform_setup.h is probably more important
if MMU changes are required (although they may not be). You'll probably
also want to change INIT_MEMORY_CONFIG for differences between EDO and
SDRAM.

But for a port to a new board I would *strongly* recommend using the
current anonymous CVS: http://sources.redhat.com/ecos/anoncvs.html as there
have been many improvements you would want.
