This patch is V2 of the MMCIF romImage boot support
for sh7724 and the Ecovec board. With this patch
applied and CONFIG_ROMIMAGE_MMCIF selected the
romImage kernel image can be written to a MMC card
and booted directly by the sh7724 cpu.

This patch adds a ->start_transfer() callback to the
KFR2R09 lcd handling code. The callback is used to
notify the lcd controller that a new frame of data
is about to be transferred. The callback is only used
in combination with deferred io, but the code has
been tested both with and without deferred io enabled.
Without this patch the display data on the KFR2R09
lcd panel becomes corrupted over time.

Early clock initialization sets up PLL/FLL values for optimal RF
behaviour. As this relationship is presently undocumented, we document
this in the script so the rationale is apparent.

This patch adds support for the WQVGA LCD display used by
the KFR2R09 board. The LCD module is a TX07D34VM0AAA made
by Hitachi, and this module is made up by a R61517 chip
together with a 240x400 pixel display. The screen is
attached to the SuperH Mobile LCDC using a 18-bit SYS bus.
The register settings used by the SYS panel setup code are
based on an out-of-tree driver which apart from duplicating
all LCDC driver code and writing to non-existing hardware
registers also never was posted for upstream merge.
