spl: Move all VPL, TPL and PowerPC specific CONFIG options to separate files
- Move all PowerPC (and some shared with Layerscape) options to
common/spl/Kconfig.nxp
- Move all other TPL related options to common/spl/Kconfig.tpl
- Move all VPL related options to common/spl/Kconfig.vpl
This makes the whole of common/spl/Kconfig slightly more readable.

+menu "TPL configuration options"
+ depends on TPL
+
+config TPL_SIZE_LIMIT
+ hex "Maximum size of TPL image"
+ default 0x0
+ help
+ Specifies the maximum length of the U-Boot TPL image.
+ If this value is zero, it is ignored.
+
+config TPL_BINMAN_SYMBOLS
+ bool "Declare binman symbols in TPL"
+ depends on SPL_FRAMEWORK && BINMAN
+ default y
+ help
+ This enables use of symbols in TPL which refer to U-Boot, enabling TPL
+ to obtain the location of U-Boot simply by calling spl_get_image_pos()
+ and spl_get_image_size().
+
+ For this to work, you must have a U-Boot image in the binman image, so
+ binman can update TPL with the location of it.
+
+config TPL_FRAMEWORK
+ bool "Support TPL based upon the common SPL framework"
+ default y if SPL_FRAMEWORK
+ help
+ Enable the SPL framework under common/spl/ for TPL builds.
+ This framework supports MMC, NAND and YMODEM and other methods
+ loading of U-Boot's SPL stage. If unsure, say Y.
+
+config TPL_BANNER_PRINT
+ bool "Enable output of the TPL banner 'U-Boot TPL ...'"
+ default y
+ help
+ If this option is enabled, TPL will print the banner with version
+ info. Disabling this option could be useful to reduce TPL boot time
+ (e.g. approx. 6 ms faster, when output on i.MX6 with 115200 baud).
+
+config TPL_HANDOFF
+ bool "Pass hand-off information from TPL to SPL and U-Boot proper"
+ depends on HANDOFF && TPL_BLOBLIST
+ default y
+ help
+ This option enables TPL to write handoff information. This can be
+ used to pass information like the size of SDRAM from TPL to U-Boot
+ proper. The information is also available to SPL if it is useful
+ there.
+
+config TPL_BOARD_INIT
+ bool "Call board-specific initialization in TPL"
+ help
+ If this option is enabled, U-Boot will call the function
+ spl_board_init() from board_init_r(). This function should be
+ provided by the board.
+
+config TPL_BOOTCOUNT_LIMIT
+ bool "Support bootcount in TPL"
+ depends on TPL_ENV_SUPPORT
+ help
+ If this option is enabled, the TPL will support bootcount.
+ For example, it may be useful to choose the device to boot.
+
+config TPL_SYS_MALLOC_SIMPLE
+ bool
+ prompt "Only use malloc_simple functions in the TPL"
+ help
+ Say Y here to only use the *_simple malloc functions from
+ malloc_simple.c, rather then using the versions from dlmalloc.c;
+ this will make the TPL binary smaller at the cost of more heap
+ usage as the *_simple malloc functions do not re-use free-ed mem.
+
+config TPL_SEPARATE_BSS
+ bool "BSS section is in a different memory region from text"
+ default y if SPL_SEPARATE_BSS
+ help
+ Some platforms need a large BSS region in TPL and can provide this
+ because RAM is already set up. In this case BSS can be moved to RAM.
+ This option should then be enabled so that the correct device tree
+ location is used. Normally we put the device tree at the end of BSS
+ but with this option enabled, it goes at _image_binary_end.
+
+config TPL_LDSCRIPT
+ string "Linker script for the TPL stage"
+ default "arch/arm/cpu/armv8/u-boot-spl.lds" if ARM64
+ default "arch/\$(ARCH)/cpu/u-boot-spl.lds"
+ help
+ The TPL stage will usually require a different linker-script
+ (as it runs from a different memory region) than the regular
+ U-Boot stage. Set this to the path of the linker-script to
+ be used for TPL.
+
+ May be left empty to trigger the Makefile infrastructure to
+ fall back to the linker-script used for the SPL stage.
+
+config TPL_NEEDS_SEPARATE_STACK
+ bool "TPL needs a separate initial stack-pointer"
+ help
+ Enable, if the TPL stage should not inherit its initial
+ stack-pointer from the settings for the SPL stage.
+
+config TPL_POWER
+ bool "Support power drivers"
+ help
+ Enable support for power control in TPL. This includes support
+ for PMICs (Power-management Integrated Circuits) and some of the
+ features provided by PMICs. In particular, voltage regulators can
+ be used to enable/disable power and vary its voltage. That can be
+ useful in TPL to turn on boot peripherals and adjust CPU voltage
+ so that the clock speed can be increased. This enables the drivers
+ in drivers/power, drivers/power/pmic and drivers/power/regulator
+ as part of an TPL build.
+
+config TPL_TEXT_BASE
+ hex "Base address for the .text section of the TPL stage"
+ default 0
+ help
+ The base address for the .text section of the TPL stage.
+
+config TPL_MAX_SIZE
+ hex "Maximum size (in bytes) for the TPL stage"
+ default 0x2e000 if ROCKCHIP_RK3399
+ default 0x8000 if ROCKCHIP_RK3288
+ default 0x7000 if ROCKCHIP_RK322X || ROCKCHIP_RK3328 || ROCKCHIP_RK3368
+ default 0x2800 if ROCKCHIP_PX30
+ default 0x0
+ help
+ The maximum size (in bytes) of the TPL stage.
+
+config TPL_STACK
+ hex "Address of the initial stack-pointer for the TPL stage"
+ depends on TPL_NEEDS_SEPARATE_STACK
+ help
+ The address of the initial stack-pointer for the TPL stage.
+ Usually this will be the (aligned) top-of-stack.
+
+config TPL_READ_ONLY
+ bool
+ depends on TPL_OF_PLATDATA
+ select TPL_OF_PLATDATA_NO_BIND
+ select TPL_OF_PLATDATA_RT
+ help
+ Some platforms (e.g. x86 Apollo Lake) load SPL into a read-only
+ section of memory. This means that of-platdata must make a copy (in
+ writeable memory) of anything it wants to modify, such as
+ device-private data.
+
+config TPL_BOOTROM_SUPPORT
+ bool "Support returning to the BOOTROM (from TPL)"
+ help
+ Some platforms (e.g. the Rockchip RK3368) provide support in their
+ ROM for loading the next boot-stage after performing basic setup
+ from the TPL stage.
+
+ Enable this option, to return to the BOOTROM through the
+ BOOT_DEVICE_BOOTROM (or fall-through to the next boot device in the
+ boot device list, if not implemented for a given board)
+
+config TPL_CRC32
+ bool "Support CRC32 in TPL"
+ default y if TPL_ENV_SUPPORT || TPL_BLOBLIST
+ help
+ Enable this to support CRC32 in uImages or FIT images within SPL.
+ This is a 32-bit checksum value that can be used to verify images.
+ For FIT images, this is the least secure type of checksum, suitable
+ for detected accidental image corruption. For secure applications you
+ should consider SHA1 or SHA256.
+
+config TPL_DRIVERS_MISC
+ bool "Support misc drivers in TPL"
+ help
+ Enable miscellaneous drivers in TPL. These drivers perform various
+ tasks that don't fall nicely into other categories, Enable this
+ option to build the drivers in drivers/misc as part of an TPL
+ build, for those that support building in TPL (not all drivers do).
+
+config TPL_ENV_SUPPORT
+ bool "Support an environment"
+ help
+ Enable environment support in TPL. See SPL_ENV_SUPPORT for details.
+
+config TPL_GPIO
+ bool "Support GPIO in TPL"
+ help
+ Enable support for GPIOs (General-purpose Input/Output) in TPL.
+ GPIOs allow U-Boot to read the state of an input line (high or
+ low) and set the state of an output line. This can be used to
+ drive LEDs, control power to various system parts and read user
+ input. GPIOs can be useful in TPL to enable a 'sign-of-life' LED,
+ for example. Enable this option to build the drivers in
+ drivers/gpio as part of an TPL build.
+
+config TPL_I2C
+ bool "Support I2C"
+ help
+ Enable support for the I2C bus in TPL. See SPL_I2C for
+ details.
+
+config TPL_LIBCOMMON_SUPPORT
+ bool "Support common libraries"
+ help
+ Enable support for common U-Boot libraries within TPL. See
+ SPL_LIBCOMMON_SUPPORT for details.
+
+config TPL_LIBGENERIC_SUPPORT
+ bool "Support generic libraries"
+ help
+ Enable support for generic U-Boot libraries within TPL. See
+ SPL_LIBGENERIC_SUPPORT for details.
+
+config TPL_MPC8XXX_INIT_DDR
+ bool "Support MPC8XXX DDR init"
+ help
+ Enable support for DDR-SDRAM on the MPC8XXX family within TPL. See
+ SPL_MPC8XXX_INIT_DDR for details.
+
+config TPL_MMC
+ bool "Support MMC"
+ depends on MMC
+ help
+ Enable support for MMC within TPL. See SPL_MMC for details.
+
+config TPL_NAND_SUPPORT
+ bool "Support NAND flash"
+ help
+ Enable support for NAND in TPL. See SPL_NAND_SUPPORT for details.
+
+config TPL_PCI
+ bool "Support PCI drivers"
+ help
+ Enable support for PCI in TPL. For platforms that need PCI to boot,
+ or must perform some init using PCI in SPL, this provides the
+ necessary driver support. This enables the drivers in drivers/pci
+ as part of a TPL build.
+
+config TPL_PCH
+ bool "Support PCH drivers"
+ help
+ Enable support for PCH (Platform Controller Hub) devices in TPL.
+ These are used to set up GPIOs and the SPI peripheral early in
+ boot. This enables the drivers in drivers/pch as part of a TPL
+ build.
+
+config TPL_RAM_SUPPORT
+ bool "Support booting from RAM"
+ help
+ Enable booting of an image in RAM. The image can be preloaded or
+ it can be loaded by TPL directly into RAM (e.g. using USB).
+
+config TPL_RAM_DEVICE
+ bool "Support booting from preloaded image in RAM"
+ depends on TPL_RAM_SUPPORT
+ help
+ Enable booting of an image already loaded in RAM. The image has to
+ be already in memory when TPL takes over, e.g. loaded by the boot
+ ROM.
+
+config TPL_RTC
+ bool "Support RTC drivers"
+ help
+ Enable RTC (Real-time Clock) support in TPL. This includes support
+ for reading and setting the time. Some RTC devices also have some
+ non-volatile (battery-backed) memory which is accessible if
+ needed. This enables the drivers in drivers/rtc as part of an TPL
+ build.
+
+config TPL_SERIAL
+ bool "Support serial"
+ select TPL_PRINTF
+ select TPL_STRTO
+ help
+ Enable support for serial in TPL. See SPL_SERIAL for
+ details.
+
+config TPL_SPI_FLASH_SUPPORT
+ bool "Support SPI flash drivers"
+ help
+ Enable support for using SPI flash in TPL. See SPL_SPI_FLASH_SUPPORT
+ for details.
+
+config TPL_SPI_FLASH_TINY
+ bool "Enable low footprint TPL SPI Flash support"
+ depends on TPL_SPI_FLASH_SUPPORT && !SPI_FLASH_BAR
+ default y if SPI_FLASH
+ help
+ Enable lightweight TPL SPI Flash support that supports just reading
+ data/images from flash. No support to write/erase flash. Enable
+ this if you have TPL size limitations and don't need full-fledged
+ SPI flash support.
+
+config TPL_SPI_LOAD
+ bool "Support loading from SPI flash"
+ depends on TPL_SPI_FLASH_SUPPORT
+ help
+ Enable support for loading next stage, U-Boot or otherwise, from
+ SPI NOR in U-Boot TPL.
+
+config TPL_SPI
+ bool "Support SPI drivers"
+ help
+ Enable support for using SPI in TPL. See SPL_SPI for
+ details.
+
+config TPL_DM_SPI
+ bool "Support SPI DM drivers in TPL"
+ help
+ Enable support for SPI DM drivers in TPL.
+
+config TPL_DM_SPI_FLASH
+ bool "Support SPI DM FLASH drivers in TPL"
+ help
+ Enable support for SPI DM flash drivers in TPL.
+
+config TPL_YMODEM_SUPPORT
+ bool "Support loading using Ymodem"
+ depends on TPL_SERIAL
+ help
+ While loading from serial is slow it can be a useful backup when
+ there is no other option. The Ymodem protocol provides a reliable
+ means of transmitting U-Boot over a serial line for using in TPL,
+ with a checksum to ensure correctness.
