spl: Make use of CONFIG_IS_ENABLED(OS_BOOT) in SPL/TPL common code paths

2021-11-05T15:23:29+00:00

When building a system that has both TPL and SPL_OS_BOOT, code which
tests for CONFIG_SPL_OS_BOOT will be built and enabled in TPL, which is
not correct.  While there is no CONFIG_TPL_OS_BOOT symbol at this time
(and likely will not ever be) we can use CONFIG_IS_ENABLED(OS_BOOT) in
these common paths to ensure we only compile these parts in the SPL
case.

arm: spl: prepare for jumping to OPTEE

2021-10-25T21:17:24+00:00

Make sure to (if applicable) flush the D-cache, invalidate I-cache,
and disable MMU and caches before jumping to OPTEE.
This fixes the SDP->SPL->OPTEE boot flow on iMX6Q and most likely on
some other ARM SoCs.

lib: optee: remove the duplicate CONFIG_OPTEE

2021-10-05T12:44:48+00:00

The configuration CONFIG_OPTEE is defined 2 times:
1- in lib/optee/Kconfig for support of OPTEE images loaded by bootm command
2- in drivers/tee/optee/Kconfig for support of OP-TEE driver.

It is abnormal to have the same CONFIG define for 2 purpose;
and it is difficult to managed correctly their dependencies.

Moreover CONFIG_SPL_OPTEE is defined in common/spl/Kconfig
to manage OPTEE image load in SPL.

This definition causes an issue with the macro CONFIG_IS_ENABLED(OPTEE)
to test the availability of the OP-TEE driver.

This patch cleans the configuration dependency with:
- CONFIG_OPTEE_IMAGE (renamed) => support of OP-TEE image in U-Boot
- CONFIG_SPL_OPTEE_IMAGE (renamed) => support of OP-TEE image in SPL
- CONFIG_OPTEE (same) => support of OP-TEE driver in U-Boot
- CONFIG_OPTEE_LIB (new) => support of OP-TEE library

After this patch, the macro have the correct behavior:
- CONFIG_IS_ENABLED(OPTEE_IMAGE) => Load of OP-TEE image is supported
- CONFIG_IS_ENABLED(OPTEE) => OP-TEE driver is supported

Remove including timestamp.h in version.h

2021-09-17T16:10:44+00:00

Header file version.h does not use anything from timestamp.h. Including of
timestamp.h has side effect which cause recompiling object file at every
make run because timestamp.h changes at every run.

So remove timestamp.h from version.h and include timestamp.h in files
which needs it.

This change reduce recompilation time of final U-Boot binary when U-Boot
source files were not changed as less source files needs to be recompiled.

SPL: Add support for parsing board / BootROM specific image types

2021-07-31T07:49:32+00:00

Platform specific BootROM may use its own image type for loading SPL or
U-Boot proper. In some cases it makes sense to not use BootROM supplied
code for booting U-Boot proper but rather to use U-Boot SPL for this,
e.g. when U-Boot SPL can load U-Boot proper faster than BootROM. In this
case it is required for platform board code to parse and load U-Boot in
BootROM specific image type.

This change adds support for parsing platform / board / BootROM specific
image types via weak function spl_parse_board_header() which is called
before marking boot image as a raw.

spl: Introduce spl_board_prepare_for_optee() hook

2021-07-27T07:47:40+00:00

OP-TEE requires some particular setup, which is not needed for linux
or other payloads. Add a hook for platform-specific code to perform
any OP-TEE related configuration and initialization.

A weak function is used because it is symmetrical to other
spl_board_prepare_for_*() implementations. A solution to avoid the use
of weak functions would trivially apply to all these implementations.
However, re-designing this is beyond the scope of this patch.
