cdrom: Add support for Sega Dreamcast GD-ROM. (74ee1a75) · Commits · 戴 / test

This patch adds support for the GD-Rom drive, SEGA's proprietary implementation of an IDE CD Rom for the SEGA Dreamcast. This driver implements Sega's Packet Interface (SPI) - at least partially. It will also read disks in SEGA's propreitary GD format. Unlike previous drivers (which were never in mainline) this uses DMA and not PIO to read disks. It is a new driver, not a refactoring of old drivers. Signed-off by: Adrian McMenamin <adrian@mcmen.demon.co.uk> Acked-by:

		A standard SEGA Dreamcast comes with a modified CD ROM drive called a
		"GD-ROM" by SEGA to signify it is capable of reading special disks
		with up to 1 GB of data. This drive will also read standard CD ROM
