[ECOS] Porting ecos 2.0 to CDB89712

[Ray Bozorg]

I am trying to port eCos 2.0 for CS89712 processor and eval board CDB89712
from
Cirrus Logic.
I have a very old patch that I am trying to use.
The question is that about the memory layout.
For EDB7312, for example ram portion (file: mlt_arm_edb7312_ram.h) see
attached.
Now I need to convert the mlt_arm_cdb89712_ram. file see attached to look
like the 7312 but I am not sure how to calculate or convert the
#define CYGMEM_SECTION_heap1_SIZE (0xfd0000 - (size_t) CYG_LABEL_NAME
(__heap1))
I am not sure where the 0xfd0000 came from can anyone help me on this issue?

Many Thanks
Ray B.
