spl: atf: add SPL_ATF_NO_PLATFORM_PARAM option

2018-01-03T13:26:57+00:00

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

binman: Add binman support to spl_ram.c

2017-12-13T02:53:45+00:00

SPL supports reading U-Boot from a RAM location. At present this is
hard-coded to the U-Boot text base address. Use binman to allow this to
come from the image file, if binman is used.

binman: Add binman symbol support to SPL

2017-12-13T02:53:45+00:00

Allow SPL to access binman symbols and use this to get the address of
U-Boot. This falls back to CONFIG_SYS_TEXT_BASE if the binman symbol
is not available.

SPL: Add FIT data-position property support

2017-12-13T02:33:38+00:00

For external data, FIT has a optional property "data-position" which
can set the external data to a fixed offset to FIT beginning.
Add the support for this property in SPL FIT.

spl: TI: Do not default to SPL_FIT_IMAGE_TINY being enabled

2017-11-28T04:05:11+00:00

This option prevents booting on am335x_evm at least along with most
likely other platforms.

spl: fit: add SPL_FIT_IMAGE_TINY config to reduce code-size

2017-11-25T23:39:08+00:00

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.

spl: atf: drop the SPL_ATF_TEXT_BASE configuration item

spl: rename config item SPL_ATF_SUPPORT to SPL_ATF

2017-11-25T23:39:07+00:00

Having CONFIG_SPL_ATF seems more natural.
Rename it, while it it is easy and there's few boards that use it
(only RK3399 and RK3368 boards).

spl: atf: introduce spl_invoke_atf and make bl31_entry private

2017-11-25T23:39:07+00:00

This adds a new interface spl_invoke_atf() that takes a spl_image_info
argument and then derives the necessary parameters for the ATF entry.
Based on the additional information recorded (into /fit-images) from
the FIT loadables, we can now easily locate the next boot stage.

We now pass a pointer to a FDT as the platform-specific parameter
pointer to ATF (so we don't run into the future headache of every
board/platform defining their own proprietary tag-structure), as
FDT access is already available in ATF.

With the necessary infrastructure in place, we can now update the
support for the ARM Trusted Firmware to dispatch into the
spl_invoke_atf function only if a IH_OS_ARM_TRUSTED_FIRMWARE image is
loaded.
