Couldn't this still be implemented entirely in Kconfig, without
modifying page.h? Like in the following example:
[...]
config VMSPLIT_1G
bool "1G/3G user/kernel split"
config VMSPLIT_X
bool "Manual split"
endchoice
config PAGE_OFFSET
hex
range 0x40000000 0xC0000000
prompt "Memory split address (must be aligned to 4096)" if VMSPLIT_X
[...]
default 0x40000000 if VMSPLIT_1G
default 0xC0000000
Cheers
Uli
