dm: timer: normalise SPL and TPL support

2017-08-13T15:12:36Z

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

2017-08-13T15:12:35Z

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. Signed-off-by: Philipp Tomsich Reviewed-by: Simon Glass

spl: support TPL_STACK, TPL_MAX_SIZE and TPL_TEXT_BASE via Kconfig

2017-08-13T15:12:34Z

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

2017-08-13T15:12:34Z

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. Signed-off-by: Philipp Tomsich Reviewed-by: Simon Glass

spl: add TPL_DRIVER_MISC_SUPPORT option

2017-08-13T15:12:21Z

This adds the TPL_DRIVER_MISC_SUPPORT option to allow activation of DRIVER_MISC_SUPPORT for devices that need it in the TPL stage. Signed-off-by: Philipp Tomsich Reviewed-by: Simon Glass Reviewed-by: Tom Rini

spl: Kconfig: split SYS_MALLOC_SIMPLE for TPL and SPL

2017-08-13T15:12:21Z

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. Signed-off-by: Philipp Tomsich Reviewed-by: Simon Glass Reviewed-by: Tom Rini

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

2017-08-13T15:12:20Z

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. Signed-off-by: Philipp Tomsich Reviewed-by: Simon Glass

spl: configure 'return to bootrom' separately for SPL and TPL

2017-08-13T15:12:19Z

On the RK3368, we want our TPL to use the 'return to bootrom' boot method (to have the bootrom load up the SPL stage) and then continue with different boot methods (MMC, SPI, etc.) from SPL. This adds the config option needed to control the availabily of the 'return to bootrom' boot-method separately for the TPL stage.

spl: add a 'return to bootrom' boot method

2017-08-13T15:12:19Z

Some devices (e.g. the RK3368) have only limited SRAM, but provide support for loading the next boot stage after our SPL performs basic setup (e.g. DRAM). For target systems like these, we add a boot device BOOTROM that will invoke a board-specific hook to return to the bootrom (if supported).

SPL: Add XIP booting support

Enable support for XIP (execute in place) of U-Boot or kernel image. There is no need to copy image from flash to ram if flash supports execute in place. Signed-off-by: Vikas Manocha Reviewed-by: Alexandru Gagniuc
