The sspi command is available in Uboot as SPI.
The sspi command is not enabled by default, but can be used by making the following modification.

File: /uboot-socfpga/include/configs/socfpga_common.h
Edit: Add #define CONFIG_CMD_SPI in the file

(e.g.) Add the following to lines 549~552.

/* 
 * SPI CMD support
 */ * SPI CMD support
#define CONFIG_CMD_SPI

(Reference) File reflecting the edited contents (Please download from the bottom of the page)
socfpga_common.h

Please refer to the following file for command usage.

File: /uboot-socfpga/common/cmd_spi.c

U_BOOT_CMD(
sspi, 5, 1, do_spi,.
"SPI utility command",.
"[<bus>:]<cs>[. <mode>] <bit_len> <dout> - Send and receive bits\n" 
"<bus> - Identifies the SPI bus", "[<bus>:]<cs>[. 
"<cs> - Identifies the chip select\n" 
"<mode> - Identifies the SPI mode to use\n" 
"<bit_len> - Number of bits to send (base 10)\n" 
"<dout> - Hexadecimal string that gets sent" 
);
