As it stands, the memory node in the u8540 Device Tree is ignored and
memory is actually stipulated by the bootloader via ATAGS. ARM core
architecture code then extracts the memory ATAG and inserts it into the
Device Tree. In the u8540 the LittleKernel bootloader only stipulates
512MB of memory; however, the u8540 actually has 2GB. We're taking the

However, platforms do exist which don't follow this convention, so

When a DMA client requests and configures a DMA channel, it requests
data_width in Bytes. The DMA40 driver then swiftly converts it over to
the necessary register bit value. Unfortunately, for any subsequent
calculations we have to shift '1' by the bit pattern (1 << data_width)
times to make any sense of it.
This patch flips the semantics on its head and only converts the value
to its respective register bit pattern when writing to registers. This
way we can use the true data_width (in Bytes) value.

We need three steps to prepare for the new Armadillo reference DT board code:
- Split the device list into r8a7740_early_devices used by the old platform
data setup (board-armadillo.c) and r8a7740_devices_dt used by both
setup variants.
- Introduce new r8a7740_init_delay() to be more flexible about calling
shmobile_setup_delay().
- For the generic r8a7740 support, we switch to device tree setup for
the GIC, the irqpin devices and the I2C controllers.
