available OpenOCD commands:
rtl8710_flash_read_id
read and parse the jedec id bytes from flash
rtl8710_flash_read_mac
read MAC address from flash memory at 0xA088
rtl8710_flash_mass_erase
erase whole flash
rtl8710_flash_read [filename] [offset] [size]
dump (size) bytes from flash offset (offset) to file (filename)
rtl8710_flash_write [filename] [offset]
write file (filename) to flash offset (offset)
rtl8710_flash_verify [filename] [offset]
compare file (filename) with flash offset (offset)
rtl8710_flash_auto_erase [1/0]
set auto_erase option on/off. flash sectors will be autoerased when writing
rtl8710_flash_auto_verify [1/0]
set auto_verify option on/off. each block of data will be auto verified when writing
