/**
|

Get IDE i/o port registers' base addresses by mode.
|
||||
|
||||
In 'Compatibility' mode, use fixed addresses.
|
||||
In Native-PCI mode, get base addresses from BARs in the PCI IDE controller's
|
||||
Configuration Space.
|
||||
|
||||
The steps to get IDE i/o port registers' base addresses for each channel
|
||||
as follows:
|
||||
|
||||
1. Examine the Programming Interface byte of the Class Code fields in PCI IDE
|
||||
controller's Configuration Space to determine the operating mode.
|
||||
|
||||
2. a) In 'Compatibility' mode, use fixed addresses shown in the Table 1 below.

Table 1. Compatibility resource mappings
|
||||
|
||||
b) In Native-PCI mode, IDE registers are mapped into IO space using the BARs
|
||||
in IDE controller's PCI Configuration Space, shown in the Table 2 below.
