0d72ba930c [POWERPC] Add workaround for MPICs with broken register reads
Some versions of PWRficient 1682M have an interrupt controller in which
the first register in each pair for interrupt sources doesn't always
read with the right polarity/sense values.

To work around this, keep a software copy of the register instead.  Since
it's not modified from the mpic itself, it's a feasible solution.  Still,
keep it under a config option to avoid wasting memory on other platforms.

bc6b73e14e [POWERPC] pasemi: Don't auto-select CONFIG_EMBEDDED
Disable auto-select of CONFIG_EMBEDDED.  ELECTRA_IDE selects
PATA_PLATFORM which should be sufficient.

8fa336d889 [POWERPC] pasemi: Electra IDE/pata_platform glue
Glue code to hook up the pata_platform on the PA Semi Electra eval board.
CFE sets up device tree entries for the IDE interface, with device type
'ide' and compatible field 'electra-ide'.

We unfortunately need to modify the resources before calling the generic
platform driver, since the device tree only has one register window in
it and the driver expects two.  Adding this as an of_platform driver
instead doesn't give us any benefit, it just adds one more layer of
register/probe functions.

Since CONFIG_PATA_PLATFORM depends on CONFIG_EMBEDDED, add that as a
default for PPC_PASEMI.

71efe45da9 [POWERPC] pasemi: CONFIG_GENERIC_TBSYNC no longer needed
Current kernel implements proper TB sync, no need to keep GENERIC_TBSYNC
enabled.

116ab40df8 [POWERPC] pasemi: Kconfig for gpio_mdio
arch/powerpc/platforms/pasemi/gpio_mdio.c really depends on CONFIG_PHYLIB.
Add a config option for it, allow for it to be disabled if needed and fix
the dependency.
