Payload size, memory size and linux kernel

[Rick Ant]

Friends,

I tried to build but can't get a good size...
Which linux kernel should i use to get 512Kbyte flash ROM or 2Mbyte Max ?
How can I compress the kernel and while loaded it's uncompressed on RAM?
I have 128Mbytes RAM and 512Kbytes ROM

Thanks
============
objcopy --gap-fill 0xff -O binary coreboot coreboot.strip
PAYLOAD=payload; if [ 0 -eq 1 ]; then PAYLOAD=/dev/null; touch cbfs-support; fi; ./buildrom coreboot.strip coreboot.rom $PAYLOAD 0x10000 0x38b400
ERROR: payload (3650704) + coreboot (65536) - Size is 144 bytes larger than ROM size (3716096).

As I keep saying, you are not going to be able to fit coreboot + kernel +
root filesystem on a 512k chip. You need a larger chip.
