Support ESP8285 (2MB flash)

Hello!
I have ESP8285 installed with 2MB flash (new version of chips).
I understand you need to edit the file boards.txt
How to make support for these chips?

tools/boards.txt.py needs to be updated (it generates boards.txt)
I wasn't aware of this new version, that's nice

Hmm that's a nice development.
What products do use this new version and how can we distinguish them?

Ah apparently it is called ESP8285H16 where the 1M version was ESP8285N08 or ESP8285H08

If it's as simple as this in boards.txt.py, I can do a quick PR for it:

    ( 'esp8285', {
        'name': 'Generic ESP8285 Module',
        'opts': {
            '.build.board': 'ESP8266_ESP01',
            '.build.variant': 'esp8285'
            },
        'macro': [
            'resetmethod_menu',
            'resetmethod_menu_extra',
            'crystalfreq_menu',
            'flashmode_dout',
            'flashfreq_40',
            '1M', '2M',  <<<
            'led',
            ],

I only have the N08 chips, so I can't verity it works correctly.

ESP8285N08 - 1 MB (–40°C ~ 85°C)
ESP8285H08 - 1 MB (–40°C ~ 105°C)
ESP8285H16 - 2 MB (–40°C ~ 105°C)

@Tech-TX I guess you're right
Also #6690 would help to have flash-size agnostic sketches
