There was an official website of Toshiba called "FlashAir Developers '', and
there was information necessary for FlashAir development, but since it closed in September 2019.
Instead, I will point an archive site for developers.
To maintain an accurate step count (which is required for correct
position recovery), any call to plan_set_position&co needs to be done
synchronously and from a halted state.
However, G92 E* is currently special-cased to skip the sync (likely to
avoid the associated performance cost), causing an incorrect E step
count and position to be set. This breaks absolute position recovery,
miscalculation of the LA factor and possibly other weird issues.
We rewrite the handling of G92 to always sync but still special-case the
frequent "G92 E0" for performance by using a free bit in the block flags.
To avoid a sync, we relay the request for reset first to the planner
which clears its internal state and then relays the request to the final
stepper isr.
According to the reprap wiki, M46 has been assigned to display its assigned IP address, but has been disabled.
Now that Toshiba FlashAir IP address processing is working, I activate the M46 code so that I can read the IP address information via serial.
W-04 needs to use CMD17 instead of CMD48 to retrieve iSDIO register memories.
To supporting both W-03 and W-04 card, I changed the readExt() code to use CMD48 first and use CMD17 if it returned some error.
This method is from the FlashAir developer sample code.

When check_z_endstop is set, Z_MIN_PIN is checkend regardless of the
moving direction to support Z calibration. This prevents the ability
to use _just_ SG when moving upwards.
But since we know the extruder is at Z_MIN, it's always safe to raise
irregardless, so we can dodge the issue.
Do not unconditionally enqueue a Z move if no move has been requested.
Since Z is calculated using the absolute current (saved) position and
scheduled for later execution, the queue order becomes relevant.
