DCIMVAC is upgraded to DCCIMVAC for the individual processor
(Cortex-A7) that the DCIMVAC is executed on.
We should follow the linux dma follow. Before DMA read, first
invalidate dcache then after DMA read, invalidate dcache again.
With the DMA direction DMA_FROM_DEVICE, the dcache need be
invalidated again after the DMA completion. The reason is
that we need explicity make sure the dcache been invalidated
thus to get the DMA'ed memory correctly from the physical memory.
Any cache-line fill during the DMA operations such as the
pre-fetching can cause the DMA coherency issue, thus CPU get the stale data.

The ci_udc driver request allocation assumes that the endpoint descriptor
pointer is set to retrieve the endpoint number, but that is only true
when the endpoint is enabled. This results in a NULL ptr dereference
which for me happens to return 0 value. This causes the EP0 request
struct to be returned for other endpoints. Some gadget drivers like
fastboot and USB MS work fine, but ethernet does not.
Really, the ci_udc driver is the oddball here doing this EP0 special
case handling Stephen added. All the other drivers alloc/free functions
are pretty much the same with the only variation being the size of the
private struct. This could all be consolidated to a common function.

This patch adds the configuration options to boot via SDIO/MMC on the
Marvell DB-88F6820-GP Armada A38x board. The default boot device
is still SPI NOR flash.
To enable MMC booting on this board 2 things need to be changes:
a) Change kwbimage.cfg
BOOT_FROM sdio
b) In the config header select
#define CONFIG_SPL_BOOT_DEVICE SPL_BOOT_SDIO_MMC_CARD
The generated image needs to be copied to the first bootable MMC
partition:
dd if=u-boot-spl.kwb of=/dev/sdX1

This patch introduces the option to boot from a MMC card parition with
an offset. This can be done by using both defines together:
define CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_PARTITION 1
define CONFIG_SYS_MMCSD_RAW_MODE_U_BOOT_SECTOR ((160 << 10) / 512)
The example above loads the main U-Boot at offset 160KiB from the MMC
partition 1.

This patch adds SPL support for the Marvell DB-88F6820-GP board.
With this change, the bin_hdr from the original Marvell U-boot
is not needed any more on this board. The sources from bin_hdr

U-Boot. And this patch enables them for this board.

This patch adds the DDR3 setup and training code taken from the Marvell
U-Boot repository. This code used to be included as a binary (bin_hdr)
into the Armada A38x boot image. Not linked with the main U-Boot. With this
code addition and the serdes/PHY setup code, the Armada A38x support
in mainline U-Boot is finally self-contained. So the complete image
for booting can be built from mainline U-Boot. Without any additional
external inclusion.
Note:
This code has undergone many hours (days!) of coding-style cleanup and
refactoring. It still is not checkpatch clean though, I'm afraid. As the
factoring of the code has so many levels of indentation that many lines
are longer than 80 chars.
