Actually this is a choice implemented using normal configs. Why not a
using a choice here:
choice
prompt "CPU Core family selection"
config ARCH_MULTI_V4_V5
bool "..."
config ARCH_MULTI_V6_V7
bool "..."
config ARCH_MULTI_V7M
bool "..."
endchoice
config ARCH_MULTI_V4T
bool "ARMv4T based platforms (ARM720T, ARM920T, ...)"
depends on ARCH_MULTI_V4_V5
config ARCH_MULTI_V5
bool "ARMv5 based platforms (ARM926T, XSCALE, PJ1, ...)" if ARCH_MULTI_V4T
depends on ARCH_MULTI_V4_V5
default y if !ARCH_MULTI_V4T
config ARCH_MULTI_V6
...
config ARCH_MULTI_V7
...
Best regards
Uwe
