-+@deffn Command {jtagspi set} bank_id name total_size page_size read_cmd unused pprg_cmd mass_erase_cmd sector_size sector_erase_cmd
-+Sets flash parameters: @var{name} human readable string, @var{total_size}
-+size in bytes, @var{page_size} is write page size. @var{read_cmd} and @var{pprg_cmd}
-+are commands for read and page program, respectively. @var{mass_erase_cmd},
-+@var{sector_size} and @var{sector_erase_cmd} are optional.
-+@example
-+jtagspi set 0 w25q128 0x1000000 0x100 0x03 0 0x02 0xC7 0x10000 0xD8
-+@end example
-+@end deffn
-+
-+@deffn Command {jtagspi cmd} bank_id resp_num cmd_byte ...
-+Sends command @var{cmd_byte} and at most 20 following bytes and reads
-+@var{resp_num} bytes afterwards. E.g. for 'Enter 4-byte address mode'
-+@example
-+jtagspi cmd 0 0 0xB7
-+@end example
-+@end deffn
-+
-+@deffn Command {jtagspi always_4byte} bank_id [ on | off ]
-+Some devices use 4-byte addresses for all commands except the legacy 0x03 read
-+regardless of device size. This command controls the corresponding hack.
