I did some testing, and it seems that images fail to boot without this set in the kernel config, with the following error: [ 0.979336] Freeing unused kernel memory: 140K (c03b1000 - c03d4000) [ 0.986659] Bad trap at PC: b7e0f60c, SR: 2d000, vector=2010 [ 0.992337] init[1]: unhandled signal 5 at 00000000 nip b7e0f60c lr b7e0f5c8 code 0 [ 1.000192] Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000005 [ 1.000192] [ 1.009293] ---[ end Kernel panic - not syncing: Attempted to kill init! exitcode=0x00000005 [ 1.009293] It's interesting, as we select all of the same configs that are set by CONFIG_BLUESTONE [0], except for APM821xx, even though we already enable the settings set by APM821xx [1], but PPC_FPU needs to be selected by a config to be enabled [2]. Because of this, I believe for the apm821xx target we will need to leave this selected unless you have any ideas. We could do a kernel patch to add a new CONFIG_IKAREM target, but then this would need to be done for every device added to this target, which is why I think just leaving CONFIG_BLUESTONE enabled would be the best plan of action.
