Until now we've been using memory beyond psci_text_end as stack space
for the secure monitor or PSCI implementation, even if space was not
allocated for it.
This was partially fixed in ("ARM: allocate extra space for PSCI stack
in secure section during link phase"). However, calculating stack space
from psci_text_end in one place, while allocating the space in another
is error prone.
This patch adds a separate empty secure stack section, with space for
CONFIG_ARMV7_PSCI_NR_CPUS stacks, each 1 KB. There's also
__secure_stack_start and __secure_stack_end symbols. The linker script
handles calculating the correct VMAs for the stack section. For
platforms that relocate/copy the secure monitor before using it, the
space is not allocated in the executable, saving space.
For platforms that do not define CONFIG_ARMV7_PSCI_NR_CPUS, a whole page
of stack space for 4 CPUs is allocated, matching the previous behavior.

Targets that define CONFIG_ARMV7_SECURE_BASE will copy the secure section
to another address before execution.
Since the secure section in the u-boot image is only storage, there's
no reason to page align it and increase the binary image size.
Page align the secure section only when CONFIG_ARMV7_SECURE_BASE is not
defined. And instead of just aligning the __secure_start symbol, align
the whole .__secure_start section. This also makes the section empty,
so we need to add KEEP() to the input entry to prevent the section from
being garbage collected.

There are two enable methods supported by ARM64 Linux; psci and
spin-table. The latter is simpler and helpful for quick SoC bring
up. My main motivation for this patch is to improve the spin-table
support, which allows us to boot an ARMv8 system without the ARM
Trusted Firmware.
Currently, we have multi-entry code in arch/arm/cpu/armv8/start.S
and the spin-table is supported in a really ad-hoc way, and I see
some problems:
- We must hard-code CPU_RELEASE_ADDR so that it matches the
"cpu-release-addr" property in the DT that comes from the
kernel tree.
- The Documentation/arm64/booting.txt in Linux requires that
the release address must be zero-initialized, but it is not
cared by the common code in U-Boot. We must do it in a board
function.
- There is no systematic way to protect the spin-table code from
the kernel. We are supposed to do it in a board specific manner,
but it is difficult to predict where the spin-table code will be
located after the relocation. So, it also makes difficult to
hard-code /memreserve/ in the DT of the kernel.
So, here is a patch to solve those problems; the DT is run-time
modified to reserve the spin-table code (+ cpu-release-addr).
Also, the "cpu-release-addr" property is set to an appropriate
address after the relocation, which means we no longer need the
hard-coded CPU_RELEASE_ADDR.

The PSCI implementation expects at most 2 pages worth of space reserved
at the end of the secure section for its stacks. If PSCI is relocated to
secure SRAM, then everything is fine. If no secure SRAM is available,
and PSCI remains in main memory, the reserved memory space doesn't cover
the space used by the stack.
If one accesses PSCI after Linux has fully booted, the memory that should
have been reserved for the PSCI stacks may have been used by the kernel
or userspace, and would be corrupted. Observed after effects include the
system hanging or telinit core dumping when trying to reboot. It seems
the init process gets hit the most on my test bed.
This fix allocates the space used by the PSCI stacks in the secure
section by skipping pages in the linker script, but only when there is
no secure SRAM, to avoid bloating the binary.
This fix is only a stop gap. It would be better to rework the stack
allocation mechanism, maybe with proper usage of CONFIG_ macros and an
explicit symbol.

The CDCE913 and CDCEL913 devices are modular PLL-based, low cost,
high performance , programmable clock synthesizers. They generate
upto 3 output clocks from a single input frequency. Each output can
be programmed for any clock-frequency.
Adding support for the same.

Adds an fdt.c file in that defines the ft_cpu_setup() function,
which should be called from a board-specific ft_board_setup()).
This ft_cpu_setup() will currently do nothing for non-secure (GP)
devices but contains pertinent updates for booting on secure (HS)
devices.
Update the omap5 Makefile to include the fdt.c in the build.

Update the CPU string output so that the device
type is now included as part of the CPU string that
is printed as the SPL or u-boot comes up. This update
adds a suffix of the form "-GP" or "-HS" for production
devices, so that general purpose (GP) and high security
(HS) can be distiguished. Applies to all OMAP5 variants.

Updates the SPL build so that when CONFIG_TI_SECURE_DEVICE
is in use (which it should be when building for secure parts),
the TI secure development package is used to create a valid
secure boot image. The u-boot SPL build processes is NOT aware
of the details of creating the boot image - all of that information
is encapsulated in the TI secure development package, which is
available from TI. More info can be found in README.ti-secure
Right now, two image types are generated, MLO and X-LOADER. The types
are important, as certain boot modes implemented by the device's ROM
boot loader require one or the other (they are not equivalent). The
output filenames are u-boot-spl_HS_MLO and u-boot-spl_HS_X-LOADER. The
u-boot-spl_HS_MLO image is also copied to a file named MLO, which is
the name that the device ROM bootloader requires for loading from the
FAT partition of an SD card (same as on non-secure devices).

Modifies the config.mk to build secure images when building
the SPL for secure devices.
Depending on the boot media, different images are needed
for secure devices. The build generates u-boot*_HS_* files
as appropriate for the different boot modes. The same u-boot
binary file is processed slightly differently to produce a
different boot image, depending on whether the user wants to
boot off SPI, QSPI or other boot media.

Defines CONFIG_TI_SECURE_DEVICE which needs to be turned on
when building images for secure devices. This flag is used
to invoke the secure image creation tools for creating a
boot image that can be used on secure devices. This flag
may also be used to conditionally compile code specific
to secure devices.
This terminology will be used by all OMAP architecture devices,
hence introducing to a common location.
With the creation of Kconfig for omap-common, moved the
sourcing of the Kconfig files for the omap3/4/5 and am33xx
devices from arch/arm/KConfig to the omap-common one.

Adding support for AM43xx secure devices require the addition
of some SOC specific config options like the amount of memory
used by public ROM and the address of the entry point of u-boot
or SPL, as seen by the ROM code, for the image to be built
correctly.
This mandates the addition of am AM43xx CONFIG option and the
ARM Kconfig file has been modified to source this SOC Kconfig
file. Moving the TARGET_AM43XX_EVM config option to the SOC
KConfig and out of the arch/arm/Kconfig.
Updating defconfigs to add the CONFIG_AM43XX=y statement and
removing the #define CONFIG_AM43XX from the header file.

Adds a new Kconfig file for AM33xx class devices. We
need a common place to define CONFIG parameters
for these SOCs, especially for adding support
for secure devices.
a) Adds a definition for ISW_ENTRY_ADDR. This is the
address to which the ROM branches when the SOC
ROM hands off execution to the boot loader.
CONFIG_SYS_TEXT_BASE and CONFIG_SPL_TEXT_BASE are set
to this value for AM43xx devices.
b) Adds CONFIG_PUB_ROM_DATA_SIZE which is used to
calculate CONFIG_SPL_MAX_SIZE. This value indicates the
amount of memory needed by the ROM to store data during
the boot process.
Currently, these CONFIG options are used only by AM43xx,
but in future other AM33xx class SOCs will also use them.
