from U-Boot. See also CMD_IDE which provides an 'ide' command for
performing various IDE operations.

+config SYS_IDE_MAXBUS
+ hex "Maximumm number of IDE buses"
+ default 2
+ help
+ This is the number of IDE buses provided by the board. Each one
+ can have one or two devices. One is designated the master and the
+ other one the slave. It is not required to have one or both on any
+ controller.
+
+config SYS_IDE_MAXDEVICE
+ hex "Maximum number of IDE devices"
+ default 2
+ help
+ This is the number of IDE devices which can be connected to the
+ board. Normally this is 2 * CONFIG_SYS_IDE_MAXBUS since up to two
+ devices can be connected to each bus. The number of devices actually
+ connected is determined by probing.
+
+config SYS_ATA_BASE_ADDR
+ hex "Base address of IDE controller"
+ default 0
+ help
+ This is the address of the IDE controller, from which other addresses
+ are calculated. Each bus is at a fixed offset from this address,
+ so it assumed that they are in the same area of the I/O space or
+ memory.
+
+config SYS_ATA_STRIDE
+ hex "IDE port stride"
+ default 0x1
+ help
+ This is the distance between each IDE register, in bytes. For an
+ 8-bit controller this is typically 1, meaning that the registers
+ appear at consecutive bytes. If the value 2 two, that might indicate
+ a 16-bit register space.
+
+config SYS_ATA_DATA_OFFSET
+ hex "Offset of the data register"
+ default 0x0
+ help
+ This is the offset of the controller's data register from the base
+ address of the controller. This is typically 0, but may be something
+ else if there are some other registers at the start of the
+ controller space.
+
+config SYS_ATA_REG_OFFSET
+ hex "Offset of the register space"
+ default 0x0
+ help
+ This is the offset of the controller's 'register' space from the base
+ address of the controller. The data register (which is typically at
+ offset 0) has its own CONFIG, to deal with controllers where it is
+ somewhere else. Register 1 will be at this offset + 1, register 2 at
+ CONFIG_SYS_ATA_REG_OFFSET + 2, etc.
+
+config SYS_ATA_ALT_OFFSET
+ hex "Offset of the alternative registers"
+ default 0x0
+ help
+ This is the offset of the controller's 'alternative' space from the
+ base address of the controller. This allows these registers to be
+ located separately from the data and register space.
+
+config SYS_ATA_IDE0_OFFSET
+ hex "Offset of bus 0"
+ default 0x1f0
+ help
+ This is the start offset of bus 0 from the start of the
+ controller registers. All the other registers are calculated from
+ this address. using the above options. For x86 hardware this is often
+ 0x1f0.
+
+config SYS_ATA_IDE1_OFFSET
+ hex "Offset of bus 1"
+ default 0x170
+ help
+ This is the start offset of bus 1 from the start of the
+ controller registers. All the other registers are calculated from
+ this address. using the above options. For x86 hardware this is often
+ 0x170.
+
+config ATAPI
+ bool "Enable ATAPI support"
+ help
+ This enabled Advanced Technology Attachment Packet Interface (ATAPI),
+ a protocol that allows a greater variety of devices to be connected
+ to the IDE port than with plain ATA. It allows SCSI commands to be
+ sent across the bus, e.g. to support optical drives.
+
+config IDE_RESET
+ bool "Support board-specific reset"
+ help
+ If this is defined, IDE Reset will be performed by calling the
+ function:
+
+ ide_set_reset(int reset)
+
+ where reset is 1 to assert reset and 0 to de-assert it. This function
+ must be defined in a board-specific file.
