Critical: L01 update to 1.8.0.b1 shrink the memory to same size as LoPY

[Colateral]

Hi,

OEM L01 is coming out of the box ver 1.7.0 that displays gc.mem_size() output 2000000 size

After OEM is updated with official tool or msys32 build the memory size is going to be shrinked

uos.uname()
(sysname='LoPy', nodename='LoPy', release='1.8.0.b1', version='v1.8.6-760-g90b72952 on 2017-09-01', machine='LoPy with ESP32', lorawan='1.0.0')

import gc
gc.mem_free()
58976

Any idea how to fix this issue in the build?

Thank you,
