This allows you to dump 0x60 bytes from the battery's EEPROM (starting at
address 0x20). Note that it does an EC command for each byte, so it's pretty
slow. OTOH, if you want to grab just a single byte from somewhere in the
EEPROM, you can do something like:
dd bs=1 count=1 skip=16 if=/sys/class/power_supply/olpc-battery/eeprom | od -x
Userspace battery collection/logging information needs this.

2. Driver sometimes would crash when receiving jumbo packets mixed
with firmware management packets. This was caused by the old

On some remote PHY blade systems, the driver receives no initial link

All variants of the 5714, 5715, and 5780 offer a feature called the
"Universal Management Port". This feature is implemented in firmware
and is largely transparent to the driver, except...
It turns out that the UMP firmware needs to know the current status
of the link. Because the firmware cannot touch the PHY registers while
the driver is in control of the device, it needs the driver to report
link status changes through an additional handshaking mechanism.
Without this handshake, it has been observed in the field that the UMP
firmware will not operate correctly.
This patch implements the new handshake with the UMP firmware. Since
the handshake uses the same mechanism ASF heartbeats use, code was
added to detect and wait for completion of a pending previous event.

The MI clock is not configured correctly on adapters with the CPMU
present. The tg3 driver has code which statically sets the MI clock to
be a fraction of the speed at which the core clock is running.
However, the CPMU can change the adapter's core clock frequency based
on operating conditions. Consequently, the MI will run slow when the
core's clock has been slowed down.
There is a new 500KHz constant frequency clock available on adapters
with a CPMU. This patch removes the static core clock scaling and
configures the MI clock to use this new 500KHz clock instead.
Running the MI clock at slower speeds will not directly result in data
corruption, but it does challenge the PHY read and write routine timeouts.

This patch (as1084b) fixes the way uhci-hcd handles polling and

neither interrupts nor polling should be enabled during a root-hub
suspend. Likewise, if interrupts are enabled during suspend then
polling isn't needed.
Furthermore the EGSM (Enter Global Suspend Mode) bit shouldn't be set
in the Command register unless remote wakeup is enabled. Apparently
some controllers will issue a remote-wakeup interrupt whenever EGSM
is on, even if Resume-Detect interrupts are supposedly disabled.
