| config SPL_STACK_R |
| depends on SPL |
| bool "Enable SDRAM location for SPL stack" |
| help |
| SPL starts off execution in SRAM and thus typically has only a small |
| stack available. Since SPL sets up DRAM while in its board_init_f() |
| function, it is possible for the stack to move there before |
| board_init_r() is reached. This option enables a special SDRAM |
| location for the SPL stack. U-Boot SPL switches to this after |
| board_init_f() completes, and before board_init_r() starts. |

| contents have not been corrupted. Note that MD5 is not considered |
| secure as it is possible (with a brute-force attack) to adjust the |
| image while still retaining the same MD5 hash value. For secure |

| consider SHA1 or SHA256. |
| |
| config SPL_SHA1_SUPPORT |

| Enable this to support SHA1 in FIT images within SPL. A SHA1 |
| checksum is a 160-bit (20-byte) hash value used to check that the |
| image contents have not been corrupted or maliciously altered. |
| While SHA1 is fairly secure it is coming to the end of its life |
| due to the expanding computing power avaiable to brute-force |

| Enable this to support SHA256 in FIT images within SPL. A SHA256 |
| checksum is a 256-bit (32-byte) hash value used to check that the |
| image contents have not been corrupted. SHA256 is recommended for |
| use in secure applications since (as at 2016) there is no known |
| feasible attack that could produce a 'collision' with differing |
| input data. Use this for the highest security. Note that only the |
| SHA256 variant is supported: SHA512 and others are not currently |

| |
| config SPL_ENV_SUPPORT |
| bool "Support an environment" |
| depends on SPL |
| help |
| Enable environment support in SPL. The U-Boot environment provides |
| a number of settings (essentially name/value pairs) which can |
| control many aspects of U-Boot's operation. Normally this is not |
| needed in SPL as it has a much simpler task with less |
| configuration. But some boards use this to support 'Falcon' boot |
| on EXT2 and FAT, where SPL boots directly into Linux without |
| starting U-Boot first. Enabling this option will make getenv() |
| and setenv() available in SPL. |
| |
| config SPL_SAVEENV |
| bool "Support save environment" |
| depends on SPL && SPL_ENV_SUPPORT |
| help |
| Enable save environment support in SPL after setenv. By default |
| the saveenv option is not provided in SPL, but some boards need |
| this support in 'Falcon' boot, where SPL need to boot from |
| different images based on environment variable set by OS. For |
| example OS may set "reboot_image" environment variable to |
| "recovery" inorder to boot recovery image by SPL. The SPL read |
| "reboot_image" and act accordingly and change the reboot_image |
| to default mode using setenv and save the environemnt. |
| |
| config SPL_ETH_SUPPORT |
| bool "Support Ethernet" |
| depends on SPL_ENV_SUPPORT |
| help |
| Enable access to the network subsystem and associated Ethernet |
| drivers in SPL. This permits SPL to load U-Boot over an Ethernet |
| link rather than from an on-board peripheral. Environment support |
| is required since the network stack uses a number of environment |
| variables. See also SPL_NET_SUPPORT. |
| |
| config SPL_EXT_SUPPORT |
| bool "Support EXT filesystems" |
| depends on SPL |
| help |
| Enable support for EXT2/3/4 filesystems with SPL. This permits |
| U-Boot (or Linux in Falcon mode) to be loaded from an EXT |
| filesystem from within SPL. Support for the underlying block |

| |
| config SPL_FAT_SUPPORT |

| |
| config SPL_FPGA_SUPPORT |
| bool "Support FPGAs" |
| depends on SPL |
| help |
| Enable support for FPGAs in SPL. Field-programmable Gate Arrays |
| provide software-configurable hardware which is typically used to |
| implement peripherals (such as UARTs, LCD displays, MMC) or |
| accelerate custom processing functions, such as image processing |
| or machine learning. Sometimes it is useful to program the FPGA |
| as early as possible during boot, and this option can enable that |
| within SPL. |
| |
| config SPL_GPIO_SUPPORT |
| bool "Support GPIO" |
| depends on SPL |
| help |
| Enable support for GPIOs (General-purpose Input/Output) in SPL. |
| 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 SPL to enable a 'sign-of-life' LED, |
| for example. Enable this option to build the drivers in |
| drivers/gpio as part of an SPL build. |
| |
| config SPL_I2C_SUPPORT |
| bool "Support I2C" |
| depends on SPL |
| help |
| Enable support for the I2C (Inter-Integrated Circuit) bus in SPL. |
| I2C works with a clock and data line which can be driven by a |
| one or more masters or slaves. It is a fairly complex bus but is |
| widely used as it only needs two lines for communication. Speeds of |
| 400kbps are typical but up to 3.4Mbps is supported by some |
| hardware. I2C can be useful in SPL to configure power management |
| ICs (PMICs) before raising the CPU clock speed, for example. |

| |
| config SPL_LIBDISK_SUPPORT |

| depends on SPL |
| help |
| Enable support for disk partitions within SPL. 'Disk' is something |
| of a misnomer as it includes non-spinning media such as flash (as |
| used in MMC and USB sticks). Partitions provide a way for a disk |
| to be split up into separate regions, with a partition table placed |
| at the start or end which describes the location and size of each |
| 'partition'. These partitions are typically uses as individual block |
| devices, typically with an EXT2 or FAT filesystem in each. This |
| option enables whatever partition support has been enabled in |
| U-Boot to also be used in SPL. It brings in the code in disk/. |
| |
| config SPL_LIBGENERIC_SUPPORT |
| bool "Support generic libraries" |
