This adds a new interface for storage devices. A driver for ATA and
ATAPI drives on AHCI host controllers comes along.
The interface is very simple and was designed to match FILO's needs.
It consists of three functions:
void storage_initialize(void);
Initializes controllers. Should be called once at startup.
storage_poll_t storage_probe(size_t dev_num);
with typedef enum {
POLL_NO_DEVICE = -2,
POLL_ERROR = -1,
POLL_NO_MEDIUM = 0,
POLL_MEDIUM_PRESENT = 1,
} storage_poll_t;
Looks for a drive with number dev_num (drives are counted from
zero) and polls for a medium in the drive if appropriate.
int storage_read_blocks512(size_t dev_num,
u64 start, size_t count,
unsigned char *buf);
Reads count blocks of 512 bytes from block start of drive dev_num
into buf.

For recent chipsets with 256 NVRAM bytes, you have to access the
|
|
upper 128 bytes (128-255) using two different I/O ports,
|
|
usually 0x72/0x73.
|
|
|
|
On some chipsets this can be a different set of ports, though.
|
|
The VIA VT8237R for example only recognizes the ports 0x74/0x75
|
|
for accessing the high 128 NVRAM bytes (as seems to be the case for
|
|
multiple VIA chipsets).

these chipsets, say 'y' here.
