Peter's and my changes to LPC1768.ld ended up adding the same AHBSRAM0
and AHBSRAM1 section clauses to the script twice. I removed one copy.
I also pulled Peter's define of the ETHMEM_SECTION macro up into the
previous nested #if so that the preprocessor wouldn't spit out a
redefined macro warning.
I verified that building the code clean before and after these changes
still results in the same .bin file but now without warnings and/or
duplicate code.
The original script assigned memory ranges to USB_RAM and ETH_RAM but
it never placed any section data in those regions. I added clauses
towards the bottom of the script to place data that the programmer
has marked for the AHBSRAM0 and AHBSRAM1 sections into these regions
of RAM. Previously the data destined for these sections was being
placed in the lower 32K RAM bank and overflowing it at link time.
I also added a few Image$$ linker symbols to mimic those used by the
online compiler. I have had samples in the past which took advantage
of these to display static memory statistics for each SRAM region.
I also changed LENGTH=0x7F38 to LENGTH=(32K - 0xC8) to make it more
consistent with the sizing of the other regions in this script which
use human readable K sizing information. The 0xC8 subtraction reflects
the starting offset of 0xC8 for this region.
