// Known open TODOs:
//
// Multi sets with heterogeneous chip types: chip0's address-line layout is
// assumed representative of the whole set — flagged, not validated against
// real hardware.
//
// Add force_8_bit including possibly new algdata to not read byte, just decide
// which byte to apply - and have the appropriate addr read delay.
//
// For force_8_bit 27c200 right now it'll use 512KB as A17 then A-1 is included.
// But in future, a new data alg that doesn't test /byte but does test A-1 and
// output correct byte, would save 256KB.
//
// Allow chip types to specify 8 bit or 16 bit only modes.  (8 bit only is
// obvious and easy)
//
// Removal of gpio_x * causes pioplugin compile problems
