bcec8f49d1 microblaze: Wire up SPI driver
Depending on XILINX_SPI_FLASH_BASEADDR enable SPI flash
and environment in SPI flash.

Expected values from xparameters.h are:
    - XILINX_SPI_FLASH_BASEADDR
    - XILINX_SPI_FLASH_MAX_FREQ
    - XILINX_SPI_FLASH_CS

09aac75e4d spi: microblaze: Adds driver for Xilinx SPI controller
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

Come from:

262350932c net: sh_eth: add SH_ETH_TYPE_ condition
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".

f8f09dd404 ARM1136: Fix cache range checks
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.

9d2d924a0a net: fec_mxc: Fix setting of RCR for xMII
At least on i.MX25, the RMII mode did not work, which is fixed by this patch.

The MII_MODE bit of the FEC RCR register means xMII, i.e. 'not 7-wire', so set
it accordingly.

According to the xMII and 7-wire (aka GPSI) standards, full duplex should be
available on xMII, but not on 7-wire, so set FCE accordingly. The FEC may
support full duplex for 7-wire too, but the reference manual does not say that,
so avoid an invalid assumption. Actually, the choice between half and full
duplex also depends on the endpoint/switch/repeater configuration, so a config
option could be added for that, but there has been no need for it so far.

usb_storage as it wrongly assumes that every transfer can use
4096 bytes per qt_buffer. This is wrong if the start address of
the data is not page aligned to 4096 bytes and leads to 'EHCI
timed out on TD' messages because of 'out of buffer pointers'
in ehci_td_buffer function.

The bug appears during load of a fragmented file and
