Sorry for the lag.

Tested on 7425b2, there is a small mistake in the interrupt number for
the AHCI controller in the 7425.dtsi file (40 -> 41, see below), after
fixing that, I get both drives (external and internal ports) to be
identified successfully:

# dmesg | grep scsi
<6>[    0.964097] scsi host0: brcm-ahci
<6>[    0.967982] scsi host1: brcm-ahci
<5>[    1.122386] scsi 0:0:0:0: Direct-Access     ATA      WDC
WD2500AAKX-7 1H19 PQ: 0 ANSI: 5
<5>[    1.124512] sd 0:0:0:0: Attached scsi generic sg0 type 0
<5>[    1.411546] scsi 1:0:0:0: Direct-Access     ATA      WDC
WD2500AAKX-7 1H19 PQ: 0 ANSI: 5
<5>[    1.428870] sd 1:0:0:0: Attached scsi generic sg1 type 0

And performance looks good:

# hdparm -tT /dev/sda

/dev/sda:
[   48.557068] random: nonblocking pool is initialized
Timing buffer-cache reads:   524 MB in 0.50 seconds = 1052111 kB/s
Timing buffered disk reads:  358 MB in 3.00 seconds = 122132 kB/s
# hdparm -tT /dev/sdb

/dev/sdb:
Timing buffer-cache reads:   528 MB in 0.50 seconds = 1060559 kB/s
Timing buffered disk reads:  374 MB in 3.00 seconds = 127496 kB/s


Tested-by: Florian Fainelli <f.fainelli@xxxxxxxxx>

For interrupt numbers, computing them from the HIF_CPU_INTR1 register
works like this this:

HW IRQ# = N * 32 + M

where N ranges from 0->2 and M is the bit within the 32-bits word.

Thanks!
