That's probably because the early EB40 boards had an AT91M40400...

But those were named EB01, as far as I know.

I think it was just decided to make use of the larger external SRAM
for eCos. Since eCos has no use for it, there was no need to mention
it in the linker scripts. It is hard to make good use of disjoint
areas of memory like this without an MMU.
The memory is still there, of course, and any application can go and
make whatever use of it it wants.

Hi,
According to the Atmel datrasheet: "...The AT91R40807 also integrates an
extended memory bank of 128K bytes at address 0x00100000..."
Can somebody explain me why this SRAM is not mentioned in the memory
layout description of the EB40?
I am new in the eCos field and probably I miss something.
Regards,
