20 help
21 Say Y here to only use the *_simple malloc functions from
22 malloc_simple.c, rather then using the versions from dlmalloc.c;
23 this will make the SPL binary smaller at the cost of more heap

26config SPL_STACK_R

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

58 Some platforms need a large BSS region in SPL and can provide this
59 because RAM is already set up. In this case BSS can be moved to RAM.
60 This option should then be enabled so that the correct device tree
61 location is used. Normally we put the device tree at the end of BSS
62 but with this option enabled, it goes at _image_binary_end.

112 32-bit checksum value that can be used to verify images. This is

122 checksum is a 128-bit hash value used to check that the image
123 contents have not been corrupted. Note that MD5 is not considered
124 secure as it is possible (with a brute-force attack) to adjust the
125 image while still retaining the same MD5 hash value. For secure
126 applications where images may be changed maliciously, you should
127 consider SHA1 or SHA256.

134 checksum is a 160-bit (20-byte) hash value used to check that the
135 image contents have not been corrupted or maliciously altered.
136 While SHA1 is fairly secure it is coming to the end of its life
137 due to the expanding computing power avaiable to brute-force
138 attacks. For more security, consider SHA256.

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

193 Enable environment support in SPL. The U-Boot environment provides
194 a number of settings (essentially name/value pairs) which can
195 control many aspects of U-Boot's operation. Normally this is not
196 needed in SPL as it has a much simpler task with less
197 configuration. But some boards use this to support 'Falcon' boot
198 on EXT2 and FAT, where SPL boots directly into Linux without
199 starting U-Boot first. Enabling this option will make getenv()
200 and setenv() available in SPL.

207 the saveenv option is not provided in SPL, but some boards need
208 this support in 'Falcon' boot, where SPL need to boot from
209 different images based on environment variable set by OS. For
210 example OS may set "reboot_image" environment variable to
211 "recovery" inorder to boot recovery image by SPL. The SPL read
212 "reboot_image" and act accordingly and change the reboot_image
213 to default mode using setenv and save the environemnt.

248 provide software-configurable hardware which is typically used to
249 implement peripherals (such as UARTs, LCD displays, MMC) or
250 accelerate custom processing functions, such as image processing
251 or machine learning. Sometimes it is useful to program the FPGA
252 as early as possible during boot, and this option can enable that
253 within SPL.

259 Enable support for GPIOs (General-purpose Input/Output) in SPL.
260 GPIOs allow U-Boot to read the state of an input line (high or
261 low) and set the state of an output line. This can be used to
262 drive LEDs, control power to various system parts and read user
263 input. GPIOs can be useful in SPL to enable a 'sign-of-life' LED,
264 for example. Enable this option to build the drivers in
265 drivers/gpio as part of an SPL build.

271 Enable support for the I2C (Inter-Integrated Circuit) bus in SPL.
272 I2C works with a clock and data line which can be driven by a
273 one or more masters or slaves. It is a fairly complex bus but is
274 widely used as it only needs two lines for communication. Speeds of
275 400kbps are typical but up to 3.4Mbps is supported by some
276 hardware. I2C can be useful in SPL to configure power management
277 ICs (PMICs) before raising the CPU clock speed, for example.

296 of a misnomer as it includes non-spinning media such as flash (as
297 used in MMC and USB sticks). Partitions provide a way for a disk
298 to be split up into separate regions, with a partition table placed
299 at the start or end which describes the location and size of each
300 'partition'. These partitions are typically uses as individual block
301 devices, typically with an EXT2 or FAT filesystem in each. This
302 option enables whatever partition support has been enabled in
303 U-Boot to also be used in SPL. It brings in the code in disk/.
