- stack is optionally in SDRAM, if CONFIG_SPL_STACK_R is defined and
CONFIG_SPL_STACK_R_ADDR points into SDRAM
- preloader_console_init() can be called here - typically this is
- done by defining CONFIG_SPL_BOARD_INIT and then supplying a

If defined, then this indicates the I2C bus number for the RTC.
If not defined, then U-Boot assumes that RTC is on I2C bus 0.
- CONFIG_SYS_DTT_BUS_NUM
-
- If defined, then this indicates the I2C bus number for the DTT.
- If not defined, then U-Boot assumes that DTT is on I2C bus 0.
-
- CONFIG_SYS_I2C_DTT_ADDR:
-
- If defined, specifies the I2C address of the DTT device.
- If not defined, then U-Boot uses predefined value for
- specified DTT device.
-
CONFIG_SOFT_I2C_READ_REPEATED_START
defining this will force the i2c_read() function in
Specify the number of FPGA devices to support.
- CONFIG_CMD_FPGA_LOADMK
-
- Enable support for fpga loadmk command
-
- CONFIG_CMD_FPGA_LOADP
-
- Enable support for fpga loadp command - load partial bitstream
-
- CONFIG_CMD_FPGA_LOADBP
-
- Enable support for fpga loadbp command - load partial bitstream
- (Xilinx only)
-
CONFIG_SYS_FPGA_PROG_FEEDBACK
Enable printing of hash marks during FPGA configuration.
Enable the hash verify command (hash -v). This adds to code
size a little.
- CONFIG_SHA1 - This option enables support of hashing using SHA1
- algorithm. The hash is calculated in software.
- CONFIG_SHA256 - This option enables support of hashing using
- SHA256 algorithm. The hash is calculated in software.
- CONFIG_SHA_HW_ACCEL - This option enables hardware acceleration
- for SHA1/SHA256 hashing.
- This affects the 'hash' command and also the
- hash_lookup_algo() function.
- CONFIG_SHA_PROG_HW_ACCEL - This option enables
- hardware-acceleration for SHA1/SHA256 progressive hashing.
- Data can be streamed in a block at a time and the hashing
- is performed in hardware.
-
Note: There is also a sha1sum command, which should perhaps
be deprecated in favour of 'hash sha1'.
This define is introduced, as the legacy image format is
enabled per default for backward compatibility.
-- FIT image support:
- CONFIG_FIT_DISABLE_SHA256
- Supporting SHA256 hashes has quite an impact on binary size.
- For constrained systems sha256 hash support can be disabled
- with this option.
-
- TODO(sjg@chromium.org): Adjust this option to be positive,
- and move it to Kconfig
-
- Standalone program support:
