d21fb63d77 spl: atf: add SPL_ATF_NO_PLATFORM_PARAM option
While we expect to call a pointer to a valid FDT (or NULL) as the
platform parameter to an ATF, some ATF versions are not U-Boot aware
and have an insufficiently robust (or an overzealour) parameter
validation: either way, this may cause a hard-stop with uncooperative
ATF versions.

This change adds the option to suppress passing a platform parameter
and will always pass NULL.

Debug output from ATF w/ this option disabled (i.e. default):
      INFO:    plat_param_from_bl2: 0x291450
Debug output from ATF w/ this option enabled:
      INFO:    plat_param_from_bl2: 0

337bbb6297 spl: fit: add SPL_FIT_IMAGE_TINY config to reduce code-size
A minor code-size increase from the changes for tracking the os-type
of FIT images and from infrastructure for recording the loadables into
the the loaded FDT, broke the builds for sun50i and some OMAP2+ devices.

This change adds a new config option (enabled by default for
MACH_SUN50I, MACH_SUN50I_H5 and ARCH_OMAP2PLUS) that does skips these
processing steps (bringing code size down to below the limit
again). The os-type is not evaluated, but assumed to be IH_OS_UBOOT
(i.e. taking the code-paths intended for backward-compatibility).

Note that enabling this config option precludes any useful downstream
processing, such as utilising a special calling convention for ATF or
OPTEE, based on the os-type of the loadables.

e9e5d9d29f dm: timer: normalise SPL and TPL support
To fully support DM timer in SPL and TPL, we need a few things cleaned
up and normalised:
- inclusion of the uclass and drivers should be an all-or-nothing
  decision for each stage and under control of $(SPL_TPL_)TIMER
  instead of having the two-level configuration with TIMER and
  $(SPL_TPL_)TIMER_SUPPORT
- when $(SPL_TPL_)TIMER is enabled, the ARMv8 generic timer code can
  not be compiled in

This normalises configuration to $(SPL_TPL_)TIMER and moves the config
options to drivers/timer/Kconfig (and cleans up the collateral damage
to some defconfigs that had SPL_TIMER_SUPPORT enabled).

089df18bfe lib: move hash CONFIG options to Kconfig
Commit 94e3c8c4fd ("crypto/fsl - Add progressive hashing support
using hardware acceleration.") created entries for CONFIG_SHA1,
CONFIG_SHA256, CONFIG_SHA_HW_ACCEL, and CONFIG_SHA_PROG_HW_ACCEL.
However, no defconfig has migrated to it.  Complete the move by first
adding additional logic to various Kconfig files to select this when
required and then use the moveconfig tool.  In many cases we can select
these because they are required to implement other drivers.  We also
correct how we include the various hashing algorithms in SPL.

This commit was generated as follows (after Kconfig additions):

[1] tools/moveconfig.py -y SHA1 SHA256 SHA_HW_ACCEL
[2] tools/moveconfig.py -y SHA_PROG_HW_ACCEL

Note:
We cannot move SHA_HW_ACCEL and SHA_PROG_HW_ACCEL simultaneously
because there is dependency between them.

bcc1726a7b spl: add support to booting with ATF
ATF(ARM Trusted Firmware) is used by ARM arch64 SoCs, find more infomation
about ATF at: https://github.com/ARM-software/arm-trusted-firmware

SPL is considered as BL2 in ATF terminology, it needs to load other parts
of ATF binary like BL31, BL32, SCP-BL30, and BL33(U-Boot). And needs to
prepare the parameter for BL31 which including entry and image information
for all other images. Then the SPL handle PC to BL31 with the parameter,
the BL31 will do the rest of work and at last get into U-Boot(BL33).

This patch needs work with patches from Andre for SPL support multi
binary in FIT.

The entry point of bl31 and bl33 are still using hard code because we
still can not get them from the FIT image information.

c0efc3140e ARM: uniphier: change CONFIG_SPL_PAD_TO to 128KB
The Boot ROM supports authentication feature to prevent malformed
software from being run on products.  The signature is added at the
tail of the second stage loader (= SPL in U-boot terminology).

The size of the second stage loader was 64KB, and it was consistent
across SoCs.  The situation changed when LD20 SoC appeared; it loads
80KB second stage loader, and it is the only exception.

Currently, CONFIG_SPL_PAD_TO is set to 64KB and U-Boot proper is
loaded from the 64KB offset of non-volatile devices.  This means the
signature of LD20 SoC (located at 80KB offset) corrupts the U-Boot
proper image.

Let's move the U-Boot proper image to 128KB offset.  It uses 48KB
for nothing but padding, and we could actually locate the U-Boot
proper at 80KB offset.  However, the power of 2 generally seems a
better choice for the offset address.

5991703e88 spl: dfu: move DFU Kconfig to SPL Kconfig
The DFU Kconfig menu entries should be part of the SPL
Kconfig file. Also avoid using the top level Makefile by
moving the config dependent build artifacts to the driver/
and driver/usb/gadget/ Makfiles.

With that, DFU can be built again in SPL if
CONFIG_SPL_DFU_SUPPORT is enabled.

Fixes: 6ad6102246 ("usb:gadget: Disallow DFU in SPL for now")

d2d9bdfcf9 spl: saveenv: adding saveenv support in SPL
By default saveenv option is not supported for SPL. This patch
enable the support for save environment variable for SPL build.

Enable save environment support in SPL after setenv. By default
the saveenv option is not provided in SPL, but some boards need
this support in 'Falcon' boot, where SPL need to boot from
different images based on environment variable set by OS. For
example OS may set "reboot_image" environment variable to
"recovery" inorder to boot recovery image by SPL. The SPL read
"reboot_image" and act accordingly and change the reboot_image
to default mode using setenv and save the environemnt.
