15 years agotsec: report when there is no vendor specific PHY support
Paul Gortmaker [Mon, 9 Mar 2009 23:07:53 +0000 (18:07 -0500)]
tsec: report when there is no vendor specific PHY support

Commit af1c2b84 added a generic phy support, with an ID of zero
and a 32 bit mask; meaning that it will match on any PHY ID.

The problem is that there is a test that checked if a matching
PHY was found, and if not, it printed the non-matching ID.
But since there will always be a match (on the generic PHY,
worst case), this test will never trip.

In the case of a misconfigured PHY address, or of a PHY that
isn't explicitly supported outside of the generic support,
you will never see the ID of 0xffffffff, or the ID of the
real (but unsupported) chip.  It will silently fall through
onto the generic support.

This change makes that test useful again, and ensures that
the selection of generic PHY support doesn't happen without
some sort of notice.  It also makes it explicitly clear that
the generic PHY must be last in the PHY table.

netloop: speed up NetLoop

NetLoop polls every cycle with getenv some environment variables.
This is horribly slow, especially when the environment is big.

This patch reads only the environment variables in NetLoop,
when they were changed.

Also moved the init part of the NetLoop function in a seperate
function.

au1x00_eth.c:158: warning: passing argument 1 of 'virt_to_phys' discards qualifiers from pointer target type

We're passing a volatile pointer to a function which is expecting a non-
volatile pointer.  That's potentially dangerous, so gcc warns about it.
Confirmed with ELDK 4.2 (GCC 4.2.2) and Sourcey G++ 4.2 (GCC 4.2.3).

To fix this, we add a volatile attribute to the argument in question.
The virt_to_phys function in Linux kernel also does the same thing.

OMAP3: Beagle: Add board revision detection

With BeagleBoard revision C some HW changes are introduced (e.g. PinMUX)
which might need different software handling. For this, GPIO pin 171 (GPIO
module 6, offset 11) can be used to check for board revision. If this pin
is low, we have a rev C board. Else it must be a revision Ax or Bx board.

To handle board differences you can call function beagle_get_revision().
E.g.:

if (beagle_get_revision()) {

/* do special revision C stuff here */

}
