Finally got enough history ripped out of my old bitkeeper repos... All I had to do to get 2GB of RAM to work on a 8266 was: CONFIG_ADVANCED_OPTIONS=y CONFIG_HIGHMEM_START_BOOL=y CONFIG_HIGHMEM_START=0xee000000 CONFIG_LOWMEM_SIZE_BOOL=y CONFIG_LOWMEM_SIZE=0x40000000 CONFIG_KERNEL_START_BOOL=y CONFIG_KERNEL_START=0xa0000000
