d5b069ecb4 DaVinci: fix ddr2 vtp i/o calibration
Previously, only the low 5 bits (NCH) were being transfered
from DDRVTPR to DDRVTPIOCR, the bits 5-9 where zeroed.

VTP_RECAL should be bit 15, not 18.

The only mainline board affected by this change is davinci_sonata.
The other Davinci boards define CONFIG_SKIP_LOWLEVEL_INIT.

However, if the program that loads u-boot on these boards
copied the code from u-boot, they will need fixed as well.

Please get tested by acks before applying, where tested by
means an overnight memory test.

41321fd4d6 ARM: OMAP5: Align memory used for testing to the power of 2
get_ram_size checks the given memory range for valid ram,
but expects the size of memory to be aligned to the power
of 2. In case of OMAP5 evm board the memory available is
2GB - 16MB(used for TRAP section) = 2032MB.

So always ensure that the size of memory used for testing is
aligned to the power of 2.

77efdeb758 ARM: OMAP5: dmm: Create a tiler trap section.
The unmapped entries in tiler space are set with
values 0xFF. So creating a DMM section of
size 16MB at 0xFF000000 with ADDRSPACE set to 0x2.

This way all the unmapped entry accesses to tiler
will be trapped by the EMIF and a error response
is sent to the L3 interconnect. L3 errors are
inturn reported to MPU.

Note that here the tiler trap section is overlapping
with the actual ddr physical space and we lose 16MB
out of the total 2GB.

e06e914d87 ARM: OMAP4+: dmm: Take care of overlapping dmm and trap sections.
The DMM sections can be overlapping with each other, with
sections 3 to 0 having the highest to lowest priority in that
order. There could also be a section that is used trap the
unmapped Tiler entries and this trap section could be
overlapping with the actual sdram area.

So take care of the above scenarios while calculating the
size of the actual ram.

f3717ac584 tegra: override compiler flags for low level init code
Override -march setting for tegra to -march=armv4t for files that are
necessary for low level init on tegra.

The recent change to use -march=armv7-a for armv7 caused a regression
on tegra because tegra starts boot on a arm7tdmi processor before
transferring control to the cortex-a9.  While still executing on the
arm7tdmi there are calls to getenv_ulong() and memset() that cause an
illegal instruction exception if compiled for armv7.

a3c3fabb0f arm, omap3: fix warm reset serial output on OMAP36xx/AM/DM37xx
In warm reset conditions on OMAP36xx/AM/DM37xx the rom code
incorrectly sets the DPLL4 clock input divider to /6.5 which
is an invalid value unless the input clock is 13MHz. When a JTAG
emulator is attached, a warm reset is necessary after the emulator
gains control of the process. This results in a loss of serial
output due to the invalid DPLL4 settings.

This patch fixes the issue by resetting the DPLL4 clock input
divider to /1 when the input clock is not 13MHz. AM/DM37x TRM
section 3.5.3.3.3.2.1 specifies that the /6.5 setting is only
used when the input clock is 13MHz.
