sounds good. you need to notice one thing... check if it could cross the [0xa0000, 0xd0000)...
ah right, I did not think of that.
I originally rewrote the nrv2b decompressor so that it delivers 1 byte per function call while not needing an additional decompression space. But unfortunately this only seems to be possible with recursive calls and it makes some 30000 recursive calls for decompressing a simple 200byte makefile. So I figured the buffer is the better solution..
To make it easier, You may just set CONFIG_TOP_MEM_K to 4096, and _RAM_START to 1M...
Why would I need to change CONFIG_LB_MEM_TOPK? It's 2048 by default, and if it's kbytes and I put _RAM_START to 1M I'd still have a whole MByte for the decompressed payload, or do I miss something?
Hm, trying to follow your suggestion while reading the code..
_RAMSTART vs _RAMBASE - What's the difference?
_RAMSTART is defined here, but never used anywhere in the whole source code... Can we kill it, or is there some code in some queue who will start using it?
src/config/Options.lb:define _RAMSTART src/mainboard/totalimpact/briq/Options.lb:default _RAMSTART=0x00100000 src/mainboard/motorola/sandpoint/Options.lb:default _RAMSTART=0x00100000 src/mainboard/motorola/sandpointx3_altimus_mpc7410/Options.lb:default _RAMSTART=0x00100000
_RAMBASE is used in many places. I assume it is supposed to be the same as _RAMSTART, but I am not sure.
