[PATCH] Make ide-cs work for hardware with 8-bit CF-Interface

Hello, it is technically possible to access a CF-Card with an 8-bit width bus. The problem with the current code is that the IDE code does a 16 (or 32) bit read on the IDE data register. If the bus interface for a 8-bit bus would then do two reads to offsets 0 and 1. The second read (to offs
