[parisc-linux] Some questions about the 715/50

[Alex deVries]

Here's a few choice entries from the inventory scan on my lovable
715/50:

2. Scorpio Core BA (11) at 0xf082f000, versions 0x7, 0x0, 0x70, 0x0,
0x0        
3. Scorpio Core SCSI (10) at 0xf0825000, versions 0x7, 0x0, 0x71, 0x0,
0x0      
4. Scorpio Core LAN (802.3) (10) at 0xf0826000, versions 0x7, 0x0, 0x72,
0x0, 00
5. Scorpio Core HIL (10) at 0xf0821000, versions 0x7, 0x0, 0x73, 0x0,
0x0       
6. Scorpio Core RS-232 (10) at 0xf0823000, versions 0x7, 0x0, 0x75, 0x0,
0x0    
...
9. Scorpio Audio (10) at 0xf1000000, versions 0x7, 0x0, 0x7b, 0x0,
0x0          
10. Scorpio EISA BA (11) at 0xfc000000, versions 0x7, 0x0, 0x76, 0x0,
0x0       

Scorpio's a 715/old, and has two IO chips in it: WAX and Lasi. Scorpio
Jr. (715/33) and Scorpio Sr. (715/75) are identical.

My questions:

a. The docs say that WAX's HIL on a GSC (not GSC+) is at 0xf0201000, but
the HIL reported above is clearly in the ASP range.  Is there actually a
HIL controller on ASP? More importantly, how are the interrupts routed?

b. What on earth is that sound chip at 0xf1000000? Is that Cherry?
