Dear Marek Just for DRAM size change do not add one more cfg file, configure by default 256MB of RAM in default kwbimg.cfg file and in function board_early_init_f() tune it to 512 for your other board version.
There's only one single bit flipped between those two kwb configs. Do you think it'd work if we just configured the system for 512MB RAM and ran get_ram_size() to see if it has only 256MB? That'd eliminate two board entries for this tk71.
I would like to have your advice on this as well Prafulla.
We have tested this on km_arm (we will have the same boards with 1/2 the RAM size) and with the above get_ram_size() it works as expected.
We still should, however, at some point (board_early_init_f() is a good candidate) then reduce the corresponding RAM CS size (reg @1504 for CS0 so that the window is the same size as what was detected by get_ram_size). What do you guys think ?
