Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

 * @munge_address:	Flag whether addresses should be munged.
 *	Some devices with 9-bit addresses (e.g. AT25040A EEPROM)
 *	use bit 3 of the command byte as address bit A8, rather
 *	than having a two-byte address.  If this flag is set, then

 * @erase_command:	Erase command (or 0 if sector erase not needed).
 * @erase_size:		Erase sector size (in bytes)
 *	Erase commands affect sectors with this size and alignment.
 *	This must be a power of two.
 * @block_size:		Write block size (in bytes).
 *	Write commands are limited to blocks with this size and alignment.
