Use the common FDT setup function that is now available in image. Move
the FDT-specific code to a new bootm-fdt.c and remove unused headers
from bootm.c.

With fewer #ifdefs the code is more readable and more of the code is
compiled for all boards. Add defines in the header file to control
what features are enabled, and then use if() instead of #ifdef.

As suggested by Stephen Warren, use tegra_get_chip() to return
the pure CHIPID for a Tegra SoC (i.e. 0x20 for Tegra20, 0x30 for
Tegra30, etc.) and rename tegra_get_chip_type() to reflect its true
function, i.e. tegra_get_chip_sku(), which returns an ID like
TEGRA_SOC_T25, TEGRA_SOC_T33, etc.

T114 needs the SYSCTR0 counter initialized so the TSC can be

Without this change, kernel fails at calling function cache_clean_flush

A start vector fix was added by AneeshV for OMAP4 (commit 0d479b53),
and caused the old monilithic Tegra builds to hang due to an undefined
instruction trap. Previously, the code needed to run on both the
AVP (ARM7TDI) and A9, and the AVP doesn't have a CP15 register.
I corrected this in commit 6d6c0bae w/#ifndef CONFIG_TEGRA, but
now that we use SPL, and boot the AVP w/o any ARMv7 code, I can
revert my change, and make Aneesh's change apply to Tegra.

Make U-Boot aware of the T33 SKU of Tegra30, and treat it identically
to any other Tegra30.
An alternative would be to simply remove the SKU checking from
tegra_get_chip_type(); most use of the value most likely simply wants
to know the current chip, not the specific SKU. Or, the function could
be split into separate tegra_get_chip() and tegra_get_sku() for the
cases where differentiation really is required.
I wonder whether tegra_get_chip_type() should printf() whenever any
unkown chip/SKU is found, although perhaps the function is called so
early that the printf() wouldn't actually make it to the UART anyway.

The KVM and Xen hypervisors for the Cortex-A15 virtualization
implementation need to be entered in HYP mode. Should the primary
board firmware already enter HYP mode (Calxeda firmware does that),
we should not deliberately drop back to SVC mode.
Since U-boot does not use the MMU, running in HYP mode is just fine.

Remove SPL-related ASSERT() in arch/arm/cpu/u-boot.lds
as this file is never used for SPL builds.
Rewrite the ASSERT() in arch/arm/cpu/u-boot-spl.lds
to separately test image (text,data,rodata...) size,
BSS size, and full footprint each against its own max,
and make Tegra boards check full footprint.
Also, output section mmutable is not used in SPL builds.
Remove it.
Finally, update README regarding the (now homogeneous)
semantics of CONFIG_SPL_[BSS_]MAX_SIZE and add the new
CONFIG_SPL_MAX_FOOTPRINT macro.

Commit 3ebd1cbc introduced compiler-generated __bss_start
and __bss_end__ and commit c23561e7 rewrote all __bss_end__
as __bss_end. Their merge caused silent and harmless but
potentially bug-inducing clashes between compiler- and linker-
generated __bss_end symbols.
Make __bss_end and __bss_start compiler-only, and create
__bss_base and __bss_limit for linker-only use.

The glitch in the SPI clock line, which commit 3cea335c34 (spi: mxc_spi: Fix spi
clock glitch durant reset) solved, is back now and itwas re-introduced by
commit d36b39bf0d (spi: mxc_spi: Fix ECSPI reset handling).
Actually the glitch is happening due to always toggling between slave mode
and master mode by configuring the CHANNEL_MODE bits in this reset function.
Since the spi driver only supports master mode, set the mode for all channels
always to master mode in order to have a stable, "glitch-free" SPI clock line.

When swi instruction is executed, it is expected to get message
"software interrupt" in console and dump registers and reboot, as
do_software_interrupt() in arch/arm/lib/interrupts.c.
But, actually it causes data abort accessing wrong address in get_bad_stack_swi
macro in arch/arm/cpu/v7/start.S.
This patch fixes this problem.

This image combines the SPL with the i.MX header, the FCB and U-Boot.
For i.MX25/35/51, the FCB is ignored by the boot ROM, so this image is just
useful because it can be programmed on a NAND Flash page boundary.
For i.MX53, the FCB is required by the boot ROM.
This does not support i.MX6 so far because its FCB is more complicated.

This image combines the SPL with the i.MX header and U-Boot. This is a
convenient way of having a single image to program on some boot devices.
The i.MX header has to be added to the SPL before appending U-Boot, so that the
boot ROM loads only the SPL.

Automatically build the 'u-boot.imx' (i.e. imx header + u-boot.bin) and 'SPL'
(i.e. imx header + u-boot-spl.bin) make targets for all imx processors
supporting this header, so for arm926ejs, arm1136 and armv7. Some combinations
were missing.
At the same time, fix the build of SPL targets not supporting the imx header on
arm1136. For arm1136, the 'SPL' make target was forced to build in all cases if
CONFIG_SPL_BUILD was defined, even for non-imx platforms or imx setups without
an imx header.

Use __image_copy_end instead of __bss_start for the end of the image to
relocate. This is the same as commit 033ca72, but applied to all ARM start.S.
This is a more appropriate symbol naming for an image copy & relocate feature,
and this also saves a useless copy of data put between __image_copy_end and
__bss_start in linker scripts (e.g. relocation information, or MMU
initialization tables used only before jumping to the relocated image).

In the case of booting from certain peripherals, such as UART, we must
not see what the device descriptor says for RAW or FAT mode because in
addition to being nonsensical, it leads to a hang. This is why we have
a test currently for the boot mode being within range. The problem
however is that on some platforms we get MMC2_2 as the boot mode and not
the defined value for MMC2, and in others we get the value for MMC2_2.
This is required to fix eMMC booting on omap5_uevm.
Tested on am335x_evm (UART, NAND, SD), omap3_beagle (NAND, SD on
classic, SD only on xM rev C5) and omap5_uevm (SD, eMMC).

Commit "8602114 omap: emif: configure emif only when required"
breaks SDRAM_AUTO_DETECTION.
The issue is dmm_init() depends on emif_sizes[](SDRAM Auto detection)
done in do_sdram_init(). The above commit moves dmm_init() above
do_sdram_init() because of which dmm_init() uses uninitialized
emif_sizes[].
So instead of using global emif_sizes[], get sdram details locally
and calculate emif sizes.

The omap2420-h4 board is using a RAM based address as the linker
location for code. This is causing several problems when attempting
to run the latest u-boot code base on this board from flash. Update
the default linker location for code to be in NOR flash. Please note
that OMAP maps the NOR flash to address 0x08000000 by default and so
use this as the default address for the NOR flash.
Also remove legacy code that attempts to calculate where in flash the
sdata structure, that holds the memory interface configuration data,
is located. By changing the default linker location for code to flash
this is no longer necessary.
