According to errata i880 description the speed of Ethernet port 1 on AM572x
SoCs rev 1.1 should be limited to 10/100Mbps, because RGMII2 Switching
Characteristics are not compatible with 1000 Mbps operation [1].
The issue is fixed with Rev 2.0 silicon.

Hence, rework Beagle-X15 and Begale-X15-revb1 to use phy-handle instead of
phy_id and apply corresponding limitation to the Ethernet Phy 1.

The Beagleboard-xM has a LAN9514 USB hub and ethernet controller,
connected to port 2 of the OMAP EHCI controller. The board however has
no EEPROM to store the ethernet MAC address, which is programmed by the
boot loader.

To allow Linux to use the same MAC address as the boot loader (or for
that matter any fixed MAC address), we need a node in the device tree
for the ethernet controller that the boot loader can update at runtime
with a local-mac-address property. Add it, along with an alias for the
ethernet controller to let the boot loader locate it easily.

Pinmuxing for DRA7x/AM57x family of processors need to be done in IO
isolation as part of initial bootloader executed from SRAM. This is
done as part of iodelay configuration sequence and is required due
to the limitations introduced by erratum ID: i869[1] (IO Glitches
can occur when changing IO settings) and elaborated in the Technical
Reference Manual[2] 18.4.6.1.7 Isolation Requirements.

Only peripheral that is permitted for dynamic pin mux configuration
is MMC and DCAN. MMC is permitted to change to accommodate the
requirements for varied speeds (which require IO-delay support in
kernel as well). DCAN is a result of i893[1] (DCAN initialization
sequence).

DCAN pinmux is retained in this patch. MMC pinmux is missing from
the dra7-evm.dts file and the board is relying on configuration done
by bootloader. A subsequent patch will add MMC pinmux configuration.

A side-effect of this patch is that NAND support is removed. NAND
pins clash with VOUT3 on DRA7-EVM. U-Boot selects VOUT3 over NAND
as per TI EVM application needs.

On chiliSOM TPS65217 nWAKEUP pin is connected to AM335x internal RTC
EXT_WAKEUP input. In RTC-only state TPS65217 is notifying about power on
events (such as power buton presses) by setting nWAKEUP output
low. After that it waits 5s for proper device boot. Currently it doesn't
happen, as the processor doesn't listen for such events. Consequently
TPS65217 changes state from SLEEP (RTC-only state) to OFF.

Enable EXT_WAKEUP input of AM335x's RTC, so the processor can properly
detect power on events and recover immediately from RTC-only states,
without powering off RTC and losing time.

I am getting the following warning when I build kernel 4.9-git on my
PowerBook G4 with a 32-bit PPC processor:

    AS      arch/powerpc/kernel/misc_32.o
  arch/powerpc/kernel/misc_32.S:299:7: warning: "CONFIG_FSL_BOOKE" is not defined [-Wundef]

This problem is evident after commit 989cea5c ("kbuild: prevent
lib-ksyms.o rebuilds"); however, this change in kbuild only exposes an
error that has been in the code since 2005 when this source file was
created.  That was with commit 9994a338 ("powerpc: Introduce
entry_{32,64}.S, misc_{32,64}.S, systbl.S").

The offending line does not make a lot of sense.  This error does not
seem to cause any errors in the executable, thus I am not recommending
that it be applied to any stable versions.

Thanks to Nicholas Piggin for suggesting this solution.

When the state names got added a script was used to add the extra argument
to the calls. The script basically converted the state constant to a
string, but the cleanup to convert these strings into meaningful ones did
not happen.

Replace all the useless strings with 'subsys/xxx/yyy:state' strings which
are used in all the other places already.
