Mtdblock driver doesn't call flush_dcache_page for pages in request. So,
this causes problems on architectures where the icache doesn't fill from
the dcache or with dcache aliases. The patch fixes this.
The ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE symbol was introduced to avoid
pointless empty cache-thrashing loops on architectures for which
flush_dcache_page() is a no-op. Every architecture was provided with this
flush pages on architectires where ARCH_IMPLEMENTS_FLUSH_DCACHE_PAGE is
equal 1 or do nothing otherwise.
See "fix mtd_blkdevs problem with caches on some architectures" discussion
on LKML for more information.

Using a device_initcall() for initializing the voltage regulator
on DA850 is not such a good idea because it gets called for all
platforms - even those who do not have a regulator implemented.
This leads to a big fat warning message during boot-up when
regulator cannot be found.
Instead, tie initialization of voltage regulator to cpufreq init.
Define a platform specific init call which in case of DA850 gets
used for initializing the regulator. On other future platforms it
can be used for other purposes.

The patch adds support for DaVinci cpu idle driver.
Two idle states are defined:
1. Wait for interrupt
2. Wait for interrupt and DDR self-refresh (or power down)
Some DaVinci SoCs support putting DDR in self-refresh (eg Dm644x, DM6467)
while others support putting DDR in self-refresh and power down (eg DM35x,
DA8xx).
Putting DDR (or mDDR) in power down saves more power than self-refresh.
The patch has been tested on DA850/OMAP-L138 EVM.

WARNING: vmlinux.o(.text+0xc2a4): Section mismatch in reference

The function da850_evm_setup_nor_nand() references

This is often because da850_evm_setup_nor_nand lacks a __initdata

Implement autodetection of RMII PHY by shifting the decision
to use the RMII PHY to da850_evm_ui_expander_setup() from
da850_evm_init() earlier.
Without this patch, selecting RMII PHY in the UI expander menu
will make the MII PHY unusable even though UI board is not
connected.
The actual configuration and registration of the EMAC device
is delayed to device_initcall() so it happens after the UI card
detection is complete.
