Since you already have built images for 256 and 128 MB configuration, so I
believe you do know how to modify the OEMAddressTable.
For memory Auto Sizing, the codes are already available in i486 CSP codes.
What you need to do is
1) let your config.bib always configured as 128 MB
2) modify the CEPC_EXTRA_RAM_START and CEPC_EXTRA_RAM_SIZE in
public\common\oak\csp\i486\inc\pc.h;
let the CEPC_EXTRA_RAM_START to be end of your minimul RAM (it is 128MB
in this scenario), and
let the CEPC_EXTRA_RAM_SIZE to be the size you want to do memory sizing.
(it is also 128MB in this scenario)
And it is still recommended that to clone the CSP codes into your BSP folder
instead of modifying in place.
