# Linking the esp8266... The Espruino source files get compiled into the .text section. The
# Espressif SDK libraries have .text and .irom0 sections. We need to put the libraries' .text into
# .iram0 (32KB on chip instruction ram) and we need to put the Esprunio .text and the libraries'
# .irom0 into .irom0 (demand-cached from flash). We do this dance by pre-linking the Espruino
# objects, then renaming .text to .irom0, and then finally linking with the SDK libraries.
# Note that a previous method of renaming .text to .irom0 in each object file doesn't work when
# we enable the link-time optimizer for inlining because it generates fresh code that all ends
# up in .iram0.
# We generate two binaries in order to support over-the-air updates, one per
# OTA partition (Espressif calls these user1.bin and user2.bin). In the 512KB flash case, there
# is only space for the first binary and updates are not possible. So we're really abusing the
# flash layout in that case because we tell the SDK that we have two 256KB partitions when in
# reality we're using one 512KB partition. This works out because the SDK doesn't use the
# user setting area that sits between the two 256KB partitions, so we can merrily use it for
