spl: kconfig: separate sysreset and firmware drivers from misc

2019-07-21T10:47:13Z

This adds separate kconfig options for drivers/sysreset and drivers/firmware. Up to now, CONFIG_SPL_DRIVERS_MISC_SUPPORT added drivers/misc to SPL build but also added drivers/firmware and drivers/sysreset at the same time. Since that is confusing, this patch uses CONFIG_SPL_SYSRESET for drivers/sysreset and adds CONFIG_SPL_FIRMWARE for drivers/firmware (and accordingly for the TPL options). CONFIG_SPL_DRIVERS_MISC_SUPPORT stays for including drivers/misc into the SPL build (and accordingly for TPL) since there are boards using non-DM (non UCLASS_MISC) files from drivers/misc. Such boards don't have CONFIG_SPL_MISC enabled, so cannot use this to include drivers/misc into the SPL build. Signed-off-by: Simon Goldschmidt

firmware: Add FIRMWARE config prompt string

2018-09-29T17:49:35Z

There is no prompt string for FIRMWARE config. Without this, FIRMWARE config cannot be enabled through menuconfing or config file. Fix this by adding prompt summary. Signed-off-by: Rajan Vaja Reviewed-by: Simon Glass

firmware: Add basic support for TI System Control Interface (TI SCI) protocol

2018-09-11T12:32:55Z

Texas Instrument's System Control Interface (TI SCI) message protocol is used in Texas Instrument's System on Chip (SoC) such as those in the K3 family AM654 SoC to communicate between various compute processors with a central system controller entity. The TI SCI message protocol provides support for management of various hardware entities within the SoC. Add support driver to allow communication with system controller entity within the SoC using the mailbox client. This is mostly derived from the TI SCI driver in Linux located at drivers/firmware/ti_sci.c.

sysreset: psci: support system reset in a generic way with PSCI

2017-04-18T14:29:19Z

If the system is running PSCI firmware, the System Reset function (func ID: 0x80000009) is supposed to be handled by PSCI, that is, the SoC/board specific reset implementation should be moved to PSCI. U-Boot should call the PSCI service according to the arm-smccc manner. The arm-smccc is supported on ARMv7 or later. Especially, ARMv8 generation SoCs are likely to run ARM Trusted Firmware BL31. In this case, U-Boot is a non-secure world boot loader, so it should not be able to reset the system directly. Signed-off-by: Masahiro Yamada
