This is an improved version of the driver patch original
submitted by Graeme Smecher <graeme.smecher@mail.mcgill.ca>
The changes are:
- remove hard coded Xilinx BSP defines (XPAR_SPI_*) and
use CONFIG_SYS_SPI_BASE from config.h instead
- add extensive register struct definitions
- remove offset calculation for register access and
use the new register struct instead
- move default SPI controller configuration from
spi_setup_slave() to spi_claim_bus()
- add spi_set_speed()
- insert SPI controller deactivation in spi_release_bus()
- protect while loops in spi_xfer() with counter / timeouts
- support SPI mode flags: LSB_FIRST, CPHA, CPOL, LOOP

At the moment, the driver supports the following CPUs:
- GETHER (Gigabit Ethernet) : SH7763, SH7734
- ETHER (Fast Ethernet) : SH7724, SH7757
And the driver had the following "#if":
#if defined(CONFIG_CPU_SH7763) || defined(CONFIG_CPU_SH7734)
#if !defined(CONFIG_CPU_SH7757) && !defined(CONFIG_CPU_SH7724)
- Those are for GETHER
#if defined(CONFIG_CPU_SH7724) || defined(CONFIG_CPU_SH7757)
- This is for ETHER
So, for clean up the code, this patch adds SH_ETH_TYPE_GETHER and
SH_ETH_TYPE_ETHER. And then, the patch modifies the above "#if".

bad_cache_range actually returned true if the range was OK, but it was used
according to its name, which resulted in all valid dcache range invalidate/flush
operations being dropped. Hence, most DMA transfers resulted in garbage data.
This patch renames this function according to what it does, and it fixes the
interpretation of its return value by other functions. The chosen naming is the
same as for ARM926EJ-S in order to be consistent.
