7c5e6f7a5d MX28: SPI: Add DMA transfer support
The DMA transfers happen only if the transfered data are larger
than 512 bytes. Otherwise PIO is used. This is a small speed
optimization.

The DMA transfer doesn't work if unaligned transfer is requested
due to the limitation of the DMA controller. This has to be fixed
by introducing generic bounce buffer. Therefore the DMA feature
is now disabled by default.

be7d257895 DaVinci DA8xx: fix set_cpu_clk_info()
For the DA8xx family of SoCs, the set_cpu_clk_info() function was not
initialising the DSP frequency, leading to 'bdinfo' command output such as:

  [...snip...]
  ARM frequency = 300 MHz
  DSP frequency = -536870913 MHz
  DDR frequency = 300 MHz

This commit provides a separate implementation of set_cpu_clk_info() for
the DA8xx SoCs that initialises the DSP frequency to zero (since
currently the DSP is not enabled by U-Boot on any DA8xx platform). The
separate implementation is justified because there is no common code
between DA8xx and the other SoC families. It is now much easier to
understand the flow of the two separate functions.
