410f525794 spl: build: ti: add support for secure boot images
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

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.

6384726d2d arm: Kconfig: Add support for AM43xx SoC specific Kconfig

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.

ce31ac7f72 arm: am33xx: Kconfig: Add secure device definitions
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.

b19236fd1c sunxi: Increase SPL header size to 64 bytes to avoid code corruption
The current SPL header, created by the 'mksunxiboot' tool, has size
32 bytes. But the code in the boot ROM stores the information about
the boot media at the offset 0x28 before passing control to the SPL.
For example, when booting from the SD card, the magic number written
by the boot ROM is 0. And when booting from the SPI flash, the magic
number is 3. NAND and eMMC probably have their own special magic
numbers too.

Currently the corrupted byte is a part of one of the instructions in
the reset vectors table:

    b     reset
    ldr   pc, _undefined_instruction
    ldr   pc, _software_interrupt      <- Corruption happens here
    ldr   pc, _prefetch_abort
    ldr   pc, _data_abort
    ldr   pc, _not_used
    ldr   pc, _irq
    ldr   pc, _fiq

In practice this does not cause any visible problems, but it's still
better to fix it. As a bonus, the reported boot media type can be
later used in the 'spl_boot_device' function, but this is out of
the scope of this patch.

If ps7_post_config() is defined call it. It is enabling for example
level shifters for PL bitstreams.

621a93e140 ARM: dts: zynq: describe SLCR as simple-mfd rather than simple-bus
Commit 9f56917ab8 ("dm: core: make simple-bus compatible to
simple-mfd") made possible to import the following commit:

Linux commit: bc5ba9b98435bf76d92e0954da1784695aa449f1

The SLCR (System-Level Control Registers) block is an MFD (Multi
Function Device) rather than a bus.

"simple-mfd" seems a more suitable compatible string than "simple-bus".

bb0c63a5f3 ARM: sama5d2: Implement boot device autodetection
Implement support for saving ARM register R4 early during boot using
save_boot_params . Implement support for decoding the stored register
R4 value in spl_boot_device() to obtain boot device from which the
SoC booted. This way, the SPL will always load U-Boot from the same
device from which the SPL itself booted instead of using hard-coded
boot device.

This functionality is useful for example when booting sama5d2-xplained
from SD card, where by default the SPL would try loading the U-Boot
from eMMC and fail. This is because eMMC is on SDHCI0 (BOOT_DEVICE_MMC1),
while SD slot is on SDHCI1 (BOOT_DEVICE_MMC2) and the SPL was hard-wired
to always boot from BOOT_DEVICE_MMC1.
