a26cd04920 arch: Make board selection choices optional
By making the board selections optional, every defconfig will include
the board selection when running savedefconfig so if a new board is
added to the top of the list of choices the former top's defconfig will
still be correct.

27e7215645 ppc4xx: Remove sc3 board
As this board seems to be unmaintained for quite some time, and its
not moved to the generic board ingrastructure, lets remove it.

This will also enable us to remove the CONFIG_AUTOBOOT_DELAY_STR2
and CONFIG_AUTOBOOT_STOP_STR2 macros, as this sc3 board is the
only one using one of this macros. A removal patch will follow
soon.

e1bfd1c6b7 powerpc/mpc85xx: Use GOT when loading IVORs post-relocation
Commit 96d2bb952b ("powerpc/mpc85xx: Don't relocate exception vectors")
simplified IVOR initialization a bit too much, failing to use the
post-relocation offset.  This doesn't cause a problem with normal NOR
boot, in which both the pre-relocation and post-relocation addresses
are 64 KiB aligned.  However, if TEXT_BASE is only 4 KiB aligned, such
as for NAND/SD/etc. boot on some targets, as well as the QEMU target,
the post-relocation address will not be the same in the lower 16 bits,
as reserve_uboot() ensures that the relocation address is always 64
KiB aligned even if the pre-relocation address was not.

Use the GOT to get the proper post-relocation offsets.

98cb0efde8 Add bootscript support to esbc_validate.
1. Default environment will be used for secure boot flow
 which can't be edited or saved.
2. Command for secure boot is predefined in the default
 environment which will run on autoboot (and autoboot is
 the only option allowed in case of secure boot) and it
 looks like this:
 #define CONFIG_SECBOOT \
 "setenv bs_hdraddr 0xe8e00000;"                 \
 "esbc_validate $bs_hdraddr;"                    \
 "source $img_addr;"                             \
 "esbc_halt;"
 #endif
3. Boot Script can contain esbc_validate commands and bootm command.
 Uboot source command used in default secure boot command will
 run the bootscript.
4. Command esbc_halt added to ensure either bootm executes
 after validation of images or core should just spin.

d87a2ad108 powerpc/mpc85xx: Remove some dead code
U-Boot does not have system calls (the services it exposes to
standalone commands use a different mechanism), so the syscall handler
is dead code.  It's also broken code, as it assumes it is located at
0xc00 -- while even before the patch to stop relocating exception
vectors to 0, U-Boot had the syscall at 0x900.

The critical and machine check return paths are never called -- the
regular exception return path is used instead, which works because
xSRR0/1 have already been saved and can be restored via the regular
SRR0/1 (we don't care too much in U-Boot about taking a critical/mcheck
inside another exception prolog/epilog).

Also remove a few other small unused functions.

96d2bb952b powerpc/mpc85xx: Don't relocate exception vectors
Booke does not require exception vectors to be located at address zero.
U-Boot was doing so anyway, simply because that's how it had been done
on other PPC.  The downside of this is that once the OS is loaded to
address zero, the exception vectors have been overwritten -- which
makes it difficult to diagnose a crash that happens after that point.

The IVOR setup and trap entry code is simplified somewhat as a result.

Also, there is no longer a need to align individual exceptions on 0x100
byte boundaries.

58d423b88e dm: select CONFIG_DM* options
As mentioned in the previous commit, adding default values in each
Kconfig causes problems because it does not co-exist with the
"depends on" syntax.  (Please note this is not a bug of Kconfig.)
We should not do so unless we have a special reason.  Actually,
for CONFIG_DM*, we have no good reason to do so.

Generally, CONFIG_DM is not a user-configurable option.  Once we
convert a driver into Driver Model, the board only works with Driver
Model, i.e. CONFIG_DM must be always enabled for that board.
So, using "select DM" is more suitable rather than allowing users to
modify it.  Another good thing is, Kconfig warns unmet dependencies
for "select" syntax, so we easily notice bugs.

Actually, CONFIG_DM and other related options have been added
without consistency: some into arch/*/Kconfig, some into
board/*/Kconfig, and some into configs/*_defconfig.

This commit prefers "select" and cleans up the following issues.

[1] Never use "CONFIG_DM=n" in defconfig files

It is really rare to add "CONFIG_FOO=n" to disable CONFIG options.
It is more common to use "# CONFIG_FOO is not set".  But here, we
do not even have to do it.
Less than half of OMAP3 boards have been converted to Driver Model.
Adding the default values to arch/arm/cpu/armv7/omap3/Kconfig is
weird.  Instead, add "select DM" only to appropriate boards, which
eventually eliminates "CONFIG_DM=n", etc.

[2] Delete redundant CONFIGs

Sandbox sets CONFIG_DM in arch/sandbox/Kconfig and defines it again
in configs/sandbox_defconfig.
Likewise, OMAP3 sets CONFIG_DM arch/arm/cpu/armv7/omap3/Kconfig and
defines it also in omap3_beagle_defconfig and devkit8000_defconfig.

       QMAN:  333.333 MHz

Top level changes include:
(1) Top level CONFIG to identify HETEROGENUOUS clusters
(2) CONFIGS for SC3900/DSP components
(3) Global structures like "cpu_type" and "MPC85xx_SYS_INFO"
    updated for dsp cores and other components
(3) APIs to get DSP num cores and their Mask like:
        cpu_dsp_mask, cpu_num_dspcores etc same as that of PowerPC
(5) Code to fetch and print SC cores and other heterogenous
    device's frequencies
(6) README added for the same

Define an _end symbol indicating the end of u-boot.bin. Also add some dummy
words into the link script to ensure that u-boot.bin will always extend
that far. There may be a better way of doing this.
