dm: timer: normalise SPL and TPL support

2017-08-13T15:12:36+00:00

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).

moveconfig: migrate TPL_STACK, TPL_TEXT_BASE and TPL_MAX_SIZE

2017-08-13T15:12:35+00:00

We can finally drop TPL_STACK, TPL_TEXT_BASE and TPL_MAX_SIZE off the
whitelist (this time it's really happening!) and migrate the setting
(only used on the RK3368-uQ7 so far) into Kconfig.

spl: support TPL_STACK, TPL_MAX_SIZE and TPL_TEXT_BASE via Kconfig

2017-08-13T15:12:34+00:00

Let's clean up behind ourselves and move the (newly defined)
TPL_STACK, TPL_MAX_SIZE and TPL_TEXT_BASE into Kconfig.  Given that
0x0 might be considered to be valid values for TPL_TEXT_BASE and
TPL_STACK, we need to introduce helper config options
("TPL_NEEDS_SEPARATE_...") to indicate that these symbols are used
(and not inherited from their SPL variants) for any given
target-platform.

spl: Kconfig: migrate $(SPL_TPL_)LDSCRIPT to Kconfig

2017-08-13T15:12:34+00:00

Now that we have split up SPL_LDSCRIPT into a SPL and TPL variant and
have started to use the TPL-variant for the RK3368, it's time to clean
up behind ourselves: move both variants into Kconfig and remove them
from the whitelist.

spl: add TPL_DRIVER_MISC_SUPPORT option

2017-08-13T15:12:21+00:00

This adds the TPL_DRIVER_MISC_SUPPORT option to allow activation of
DRIVER_MISC_SUPPORT for devices that need it in the TPL stage.

spl: consistently use $(SPL_TPL_) to select features for SPL and TPL builds

2017-08-13T15:12:21+00:00

To allow for a finer-grained control of features for TPL and SPL
builds all modules/boot-methods/etc. need to be consistently selected
based on the $(SPL_TPL_) macros.

This allows splitting the associated config-options in Kconfig: we
don't split the Kconfig options here and now, as this should happen on
an as-needed basis, whenever someone needs a feature/boot-method/etc.
in their TPL.

spl: Kconfig: split SYS_MALLOC_SIMPLE for TPL and SPL

2017-08-13T15:12:21+00:00

As include/malloc.h already checks for SYS_MALLOC_SIMPLE using the
CONFIG_IS_ENABLED macro, we need to move to having separate entries
as we switch to fully separate configuration for SPL and TPL.

spl: dm: use CONFIG_IS_ENABLED to test for the DM option

2017-08-13T15:12:20+00:00

Even though there's now a TPL_DM configuration option, the spl logic
still checks for SPL_DM and thus does not pick up the proper config
option.

This introduces the use of CONFIG_IS_ENABLED(DM) in spl.c to always
pick up the desired configuration option instead of having a
hard-coded check for the SPL variant.

spl: dm: Kconfig: fix help text for SPL/TPL confusion

2017-08-13T15:12:20+00:00

TPL_NAND_SUPPORT, TPL_SERIAL_SUPPORT, TPL_SPI_FLASH_SUPPORT and
TPL_SPI_SUPPORT refer to SPL in their help text.  This fixes up
the description to correctly reference TPL.

spl: use TPL_SYS_MALLOC_F_LEN for TPL

2017-08-13T15:12:19+00:00

The (upstream) changes to break up SYS_MALLOC_F_LEN for the full
U-Boot and the SPL stage, break TPL (if simple malloc is enabled in
TPL).

This adds support for a TPL-variant of SYS_MALLOC_F_LEN:
- adds TPL_SYS_MALLOC_F_LEN
- rewrites a test for CONFIG_SPL_SYS_MALLOC_F_LEN to access
  CONFIG_VAL(SYS_MALLOC_F_LEN)
