DaVinci EMAC is present on TI AM35xx SoCs (ARMv7) which run with D-Cache
enabled by default. So we have to take care and flush/invalidate the
cache before/after the DMA operations.
Please note that the receive buffer alignment to 32 byte boundary comes
from the old driver version I don't know if it is really needed or
alignment to cache line size is enough.

also. This patch moves common defines from arch-davinci/emac_defs.h to

Change the CONFIG_SYS_TEXT_BASE and the addresses of SDRAM
buffers used by SPL(heap and BSS) keeping in mind the
following requirements:
1. Make sure that SPL's heap and BSS doesn't come in the way
of Linux kernel, which is typically loaded at 0x80008000. This
will be important when SPL directly loads kernel.
2. Align the CONFIG_SYS_TEXT_BASE between TI internal
U-Boot and mainline U-Boot. This avoids a lot of confusion
and allows for the inter-operability of x-loader, SPL,
internal U-Boot, mainline U-Boot etc. The internal U-Boot's
address can not be changed to that of mainline U-Boot
as internal U-Boot doesn't have relocation and 0x80100000
used by mainline U-Boot will clash with kernel
3. Assume only a minimum amount of memory that may be available
on any practical OMAP4/5 board in future too. We are assuming
a minimum of 128 MB of memory

There was a typo in the EMIF driver. It went un-noticed
because it affected only when automatic detection is enabled

TPS power IC is controlled using a GPIO (gpio_wk7).
This GPIO should be maintained at logic 1 always. As
such an internal pull-up on this pin will do the job,
driving the GPIO outuput is not needed. This will avoid
the need of using GPIO library in SPL and also may
save some power.

We were not disabling external caches before jumping
to kernel. We were flushing all caches including
external caches and disabling caches globally in
CP15 System Control register. Apparently this is not
enough.
The bootstrap loader in Linux kernel that does decompression
enables data-caches again, flush them after use and disable
them before jumping to kernel proper. However, it's not aware
of the external caches.
Since we have left external cache enabled, external cache will
get used once caches are enabled globally, but it's not flushed
because decompressor is not aware of external caches. When it
jumps to kernel with caches disabled globally, we have stale
data in the external cache and a coherency problem.
This was breaking the boot for OMAP4 with latest mainline
kernel. The solution is to disable external caches in
cleanup_before_linux(). With this fix kernel is booting again.
