5f603761c3 ARM: DRA7 / OMAP5: Add workaround for ARM errata 798870
This patch enables the workaround for ARM errata 798870 for OMAP5 /
DRA7 which says "If back-to-back speculative cache line fills (fill
A and fill B) are issued from the L1 data cache of a CPU to the
L2 cache, the second request (fill B) is then cancelled, and the
second request would have detected a hazard against a recent write or
eviction (write B) to the same cache line as fill B then the L2 logic
might deadlock."

An l2auxctlr accessor implementation for OMAP5 and DRA7 is introduced
here as well.

a70e157f30 configs: omap5_common : Boot rootfs from sd card by default
* Since the emmc isn't always programed trying to load the fs from the
  emmc causes boot failures/kernel panic.

* The current bootcmd is set to:
  bootcmd=run findfdt; run mmcboot;setenv mmcdev 1; setenv bootpart 1:2; \
  setenv mmcroot /dev/mmcblk0p2 rw; run mmcboot;

My guess is the env variables should be set so that sd card boot
(dt,kernel,fs) is the default and then fallback to emmc if it fails (no
sd card detected)

The current bootcmd attempts to set mmcroot to the sd card rootfs but
that code doesn't run due to mmcboot being ran early on.

ba2e01c72b arm: omap5: don't enable misc_init_r by default
Out of all OMAP5-like boards, only one of them
needs CONFIG_MISC_INIT_R, so it's best to enable
that for that particular board only, instead of
enabling for all boards unconditionally.

6c5431ac81 omap5: kconfig: move board select menu and common settings
Becuase the board select menu in arch/arm/Kconfig is too big,
move the OMAP5 board select menu to omap5/Kconfig.

Move also common settings (CONFIG_SYS_CPU="armv7" and
CONFIG_SYS_SOC="omap5").

d3289aac64 TI:armv7: Change Falcon Mode DT load address
In general, we want to load the DT at base+128MB, so that we ahve
sufficient room for the kernel and a larger device tree.  In the case of
OMAP3, use 64MB instead as we have a number of boards with 128MB DDR.

fb3ad9bd92 TI: Add, use a DEFAULT_LINUX_BOOT_ENV environment string
To deal with a reoccurring problem properly we need to specify addresses
for the Linux kernel, Flatted Device Tree and ramdisk that obey the
constraints within the kernel's Documentation/arm/Booting file but also
make sure that we relocate things within a valid address range.

It is possible with these addresses to also set fdt_high and initrd_high
to the value of 0xffffffff.  We don't do this by default to allow for
the most likely success of people using custom addresses however.
