Mysql db full schema generation - no tinyint/boolean

What steps will reproduce the problem?

1. create a mysql table with tinyint(1) column

2. cake migrate g from db

3. look at full_schema.yml

What is the expected output? What do you see instead? Expected:

UP:

create_table:

table_name:
  tinyint_column:
    type: boolean
    not_null:

But got: ...

  tinyint_column:
    type: integer
    length: 11
    not_null:

It is Mysql-Db, i dont know if it works or not on another DB.
