config VPL_BANNER_PRINT
|
|
bool "Enable output of the VPL banner 'U-Boot VPL ...'"
|
|
default y
|
|
help
|
|
If this option is enabled, VPL will print the banner with version
|
|
info. Disabling this option could be useful to reduce VPL boot time
|
|
(e.g. approx. 6 ms faster, when output on i.MX6 with 115200 baud).
|
|
|
|
config VPL_BOARD_INIT
|
|
bool "Call board-specific initialization in VPL"
|
|
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.

bool "Support CRC32 in VPL"
|
|
default y if VPL_ENV_SUPPORT || VPL_BLOBLIST
|
|
help
|
|
Enable this to support CRC32 in uImages or FIT images within VPL.
|
|
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 VPL_DM_SPI
|

help
|
|
Enable support for SPI DM drivers in VPL.

help
|

Enable support for SPI DM flash drivers in VPL.
|
|
|
|
config VPL_FRAMEWORK
|
|
bool "Support VPL based upon the common SPL framework"
|
|
default y
|
|
help
|
|
Enable the SPL framework under common/spl/ for VPL builds.
|
|
This framework supports MMC, NAND and YMODEM and other methods
|
|
loading of U-Boot's next stage. If unsure, say Y.
|

|
|
bool "Pass hand-off information from VPL to SPL"
|
|
depends on HANDOFF && VPL_BLOBLIST
|
|
default y
|
|
help
|
|
This option enables VPL to write handoff information. This can be
|
|
used to pass information like the size of SDRAM from VPL to SPL. Also
|
|
VPL can receive information from TPL in the same place if that is
|
|
enabled.
|

|
|
config VPL_LIBCOMMON_SUPPORT
|
|
bool "Support common libraries"

Enable support for common U-Boot libraries within VPL. See

SPL_LIBCOMMON_SUPPORT for details.
|
|
|
|
config VPL_LIBGENERIC_SUPPORT
|
|
bool "Support generic libraries"
|
|
default y if SPL_LIBGENERIC_SUPPORT
|
|
help
|
|
Enable support for generic U-Boot libraries within VPL. These
|
|
libraries include generic code to deal with device tree, hashing,
|
|
printf(), compression and the like. This option is enabled on many
|
|
boards. Enable this option to build the code in lib/ as part of a

|
VPL build.

default y if TPL_DRIVERS_MISC
|

help
|

Enable miscellaneous drivers in VPL. 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 a VPL
|
|
build, for those that support building in VPL (not all drivers do).
|
|
|
|
config VPL_ENV_SUPPORT
|
|
bool "Support an environment"
|
|
help
|
|
Enable environment support in VPL. The U-Boot environment provides
|
|
a number of settings (essentially name/value pairs) which can
|
|
control many aspects of U-Boot's operation. Enabling this option will
|
|
make env_get() and env_set() available in VSPL.
|
|
|
|
config VPL_GPIO
|
|
bool "Support GPIO in VPL"
|
|
default y if SPL_GPIO
|
|
help
|
|
Enable support for GPIOs (General-purpose Input/Output) in VPL.
|
|
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 VPL to enable a 'sign-of-life' LED,
|
|
for example. Enable this option to build the drivers in
|
|
drivers/gpio as part of a VPL build.
|
|
|

bool "Pass hand-off information from VPL to SPL and U-Boot proper"
|
|
depends on HANDOFF && VPL_BLOBLIST
|
|
default y
|
|
help
|
|
This option enables VPL to write handoff information. This can be
|
|
used to pass information like the size of SDRAM from VPL to U-Boot
|
|
proper. The information is also available to VPL if it is useful
|
|
there.
|
|
|

select SHA1
|
|
select SHA256
|
|
help
|
|
Enable hashing drivers in VPL. These drivers can be used to
|
|
accelerate secure boot processing in secure applications. Enable
|
|
this option to build system-specific drivers for hash acceleration
|
|
as part of a VPL build.
|
|
|
|
config VPL_I2C_SUPPORT
|
|
bool "Support I2C in VPL"

bool "Support MMC in VPL"
|
|
depends on VPL && MMC
|
|
default y if MMC
|
|
help
|
|
Enable support for MMC (Multimedia Card) within VPL This enables
|
|
the MMC protocol implementation and allows any enabled drivers to
|
|
be used within VPL. MMC can be used with or without disk partition
|
|
support depending on the application (SPL_LIBDISK_SUPPORT). Enable
|
|
this option to build the drivers in drivers/mmc as part of an VPL
|
|
build.
|

|
|
default y
|

help
|
|
This enables the MultiMediaCard (MMC) uclass which supports MMC and
|
|
Secure Digital I/O (SDIO) cards. Both removable (SD, micro-SD, etc.)
|
|
and non-removable (e.g. eMMC chip) devices are supported. These
|
|
appear as block devices in U-Boot and can support filesystems such
|
|
as EXT4 and FAT.

default y if TPL_PCH_SUPPORT
|
|
help
|
|
Enable support for PCH (Platform Controller Hub) devices in VPL.
|
|
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 VPL
|
|
build.
|
|
|
|
config VPL_PCI
|
|
bool "Support PCI drivers"
|
|
default y if SPL_PCI
|
|
help
|
|
Enable support for PCI in VPL. For platforms that need PCI to boot,
|
|
or must perform some init using PCI in VPL, this provides the
|
|
necessary driver support. This enables the drivers in drivers/pci
|
|
as part of a VPL build.
|
|
|
|
config VPL_RTC
|
|
bool "Support RTC drivers"
|
|
help
|
|
Enable RTC (Real-time Clock) support in VPL. 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 a VPL
|
|
build.
|
|
|
|
config VPL_SERIAL
|
|
bool "Support serial"
|
|
default y if TPL_SERIAL

Enable support for using SPI in VPL. See SPL_SPI_SUPPORT for
|
|
details.
|
|
|
|
config VPL_SPI_FLASH_SUPPORT
|
|
bool "Support SPI flash drivers"
|
|
help
|
|
Enable support for using SPI flash in VPL, and loading U-Boot from
|
|
SPI flash. SPI flash (Serial Peripheral Bus flash) is named after
|
|
the SPI bus that is used to connect it to a system. It is a simple
|
|
but fast bidirectional 4-wire bus (clock, chip select and two data
|
|
lines). This enables the drivers in drivers/mtd/spi as part of a
|
|
VPL build. This normally requires VPL_SPI_SUPPORT.
|
|
|
|
config VPL_TEXT_BASE
|
|
hex "VPL Text Base"

config VPL_BINMAN_SYMBOLS
|
|
bool "Declare binman symbols in VPL"
|
|
depends on VPL_FRAMEWORK && BINMAN
|
|
default y
|
|
help
|
|
This enables use of symbols in VPL which refer to other entries in
|
|
the same binman image as the VPL. These can be declared with the
|
|
binman_sym_declare(type, entry, prop) macro and accessed by the
|
|
binman_sym(type, entry, prop) macro defined in binman_sym.h.
|
|

config VPL_BINMAN_UBOOT_SYMBOLS

bool "Declare binman symbols for U-Boot phases in VPL"
|
|
depends on VPL_BINMAN_SYMBOLS
|
|
default n if ARCH_IMX8M || ARCH_IMX9
|
|
default y
|
|
help
|
|
This enables use of symbols in VPL which refer to U-Boot phases,
|
|
enabling VPL to obtain the location and size of its next phase simply
|
|
by calling spl_get_image_pos() and spl_get_image_size().
|
|
|
|
For this to work, you must have all U-Boot phases in the same binman
|
|
image, so binman can update VPL with the locations of everything.
