41aebf8106 omap4/5/am33xx: Make lowlevel_init available to all armv7 platforms
Make the lowlevel_init function that these platforms have which just
sets up the stack and calls a C function available to all armv7
platforms.  As part of this we change some of the macros that are used
to be more clear.  Previously (except for am335x evm) we had been
setting CONFIG_SYS_INIT_SP_ADDR to a series of new defines that are
equivalent to simply referencing NON_SECURE_SRAM_END.  On am335x evm we
should have been doing this initially and do now.

e423a8f76d ARM: OMAP4: Correct the lpddr2 io settings register value.
To meet certain timing requirements on the lpddr2 cmd and data phy
interfaces ,lpddr iopads have to be configured as differential buffers
and a Vref has to be internally generated and provided to these buffers.

Correcting the above settings here.

d417d1db5f OMAP3+: reset: Create a common reset layer.
The reset.S has the function to do a warm reset on OMAP
based socs. Moving this to a reset.c file so that this
acts a common layer to add any reset related functionality
for the future.

002a2c0c66 OMAP4/5: Make the sysctrl structure common
Make the sysctrl structure common, so that it can
be used in generic functions across socs.
Also change the base address of the system control module, to
include all the registers and not simply the io regs.

fe7104b307 omap4: fix boot issue on ES2.0 Panda
Fix boot issue on ES2.0 Panda by tuning some
IO settings. The CONTROL_EFUSE_2 register has
to be over-ridden in software for 4430 boards.

Commit 23e9f0723e
wrongly did this for CONTROL_EFUSE_1. Reverting
this and doing it for CONTROL_EFUSE_2.

78f455c055 omap4/5: Add support for booting with CH.
Configuration header(CH) is 512 byte header attached to an OMAP
boot image that will help ROM code to initialize clocks, SDRAM
etc and copy U-Boot directly into SDRAM. CH can help us in
by-passing SPL and directly boot U-boot, hence it's an alternative
for SPL. However, we intend to support both CH and SPL for OMAP4/5.

Initialization done through CH is limited and is not equivalent
to that done by SPL. So U-Boot has to distinguish between the
two cases and handle them accordingly. This patch takes care
of doing this.

508a58fa8e omap5: Add minimal support for omap5430.
This patch adds the minimal support for OMAP5. The platform and machine
specific headers and sources updated for OMAP5430.

OMAP5430 is Texas Instrument's SOC based on ARM Cortex-A15 SMP architecture.
It's a dual core SOC with GIC used for interrupt handling and SCU for cache
coherency.

Also moved some part of code from the basic platform support that can be made
common for OMAP4/5. Rest is kept out seperately. The same approach is followed
for clocks and emif support in the subsequent patches.
