Since commit 326a6823 (malloc_f: enable SYS_MALLOC_F by default
if DM is on), Zynq MMC boot hangs up after printing the following:

    U-Boot SPL 2015.04-rc5-00053-gadcc5705 (Apr 08 2015 - 12:59:11)
    mmc boot
    reading system.dtb

Prior to commit 326a6823, Zynq boards enabled CONFIG_DM, but
not CONFIG_SYS_MALLOC_F.  That commit forcibly turned on
CONFIG_SYS_MALLOC_F.  I have not figured out the root cause, but
anyway it looks like CONFIG_SYS_MALLOC_F gave a bad impact on the
Zynq MMC boot.

We are planning to have the v2015.04 release in a few days.
I know this is a defensive fixup, but what I can do now is to add
   # CONFIG_SYS_MALLOC_F is not set
to every Zynq defconfig file to get back the original behavior.

Tested on:
  - Zedboard
  - ZC706 board

Since the Kconfig conversion, boards.cfg scanned by MAKEALL is
generated by tools/genboardscfg.py.  Every board is supposed to have
its own MAINTAINERS that contains maintainer and status information,
but, in fact, MAINTAINERS is missing from some boards.

For such boards, the first field, Status, is filled with '-'.
It causes a problem for "set" command, which ignores '-' in its
arguments.  Consequently, get_target_arch() returns a wrong field
and MAKEALL fails to get a correct toolchain.

Since the Kconfig conversion, config.mk has been included only when
include/config/auto.conf is newer than the .config file.

It causes build error if both files have the same time-stamps.
It is actually possible because EXT* file systems have a 1s time-stamp
resolution.

The config.mk should be included when include/config/auto.conf is
*not older* than the .config file.

Back in fc46bae2 a "clean up" was introduced that intended to reconcile
some of the AM335x codepaths based on how AM43xx operates.
Unfortunately this introduced a regression on the DDR2 platforms.  This
was un-noticed on DDR3 (everything except for Beaglebone White) as we
had already populated sdram_config correctly in sequence.  This change
brings us back to the older behavior and is fine on all platforms.

In stead of user_buffer_size, transfer_size should be used to pass to
ahci_device_data_io(). transfer_size is the length that we want the
low level function to transfer each time.
If we use user_buffer_size which is the totally data length as parameter,
low level function will actually create many SGs to transfer as many data
as possible each time. That will produce many redundant data transfer.

The u-boot environment is redundantly stored in a NOR flash on our boards.
Redundant means that there are two places to store the environment. But only
one of the two is active. I discovered that on one board the u-boot (env_sf)
uses the environment from the second place and the Kernel (fw_printenv) uses
the environment from the first place.
To decide which is the active environment there is a byte inside the
environment. 1 means active and 0 means obsolete. But on that board both
environments had have a 1. This can happen if a power loss or reset occurs
during writing the environment. In this situation the u-boot (env_sf)
implementation uses the second environment as default. But the Kernel
(fw_printenv) implementation uses the first environment as default.

This commit corrects the default in the u-boot env_sf implementation when a
problem was detected. Now the recovery default is the same like in all other
environment implementations. E.g. fw_printenv and env_flash. This ensures that
u-boot and Kernel use the same environment.

The existing setting for rpll_sdiv generates 70.5Mhz RPLL
video clock to drive 1366x768 panel on peach_pit.

This clock rate is not sufficient to drive 1920x1080 panel on peach-pi.
So, we adjust rpll_sdiv to 3 so that it generates 141Mhz pixel clock
which can drive peach-pi LCD.

This change doesn't break peach-pit LCD since 141/2=70.5Mhz, i.e FIMD
divider at IP level will get set to 1(the required divider setting
will be calculated and set by exynos_fimd_set_clock()) and hence
peach-pit LCD still works fine.

The peach boards have their SDRAM start address at 0x20000000 instead of
0x40000000 which seems common for all other exynos5 based boards. This
means the layout set in exynos5-common.h causes the kernel be loaded
more then 128MB (at 0x42000000) away from memory start which breaks
booting kernels with CONFIG_AUTO_ZRELADDR

Define a custom MEM_LAYOUT_ENV_SETTINGS for both peach boards which uses
the same offsets from start of memory as the common exynos5 settings.

This fixes booting via bootz and PXE

ARCv2 cores may have built-in SLC (System Level Cache, AKA L2-cache).
This change adds functions required for controlling SLC:
 * slc_enable/disable
 * slc_flush/invalidate

For now we just disable SLC to escape DMA coherency issues until either:
 * SLC flush/invalidate is supported in DMA APIin U-Boot
 * hardware DMA coherency is implemented (that might be board specific
   so probably we'll need to have a separate Kconfig option for
   controlling SLC explicitly)
