+ * cmd_get_data_size() - Get the data-size specifier from a command
|
|
|
+ *
|
|
|
+ * This reads a '.x' size specifier appended to a command. For example 'md.b'
|
|
|
+ * is the 'md' command with a '.b' specifier, meaning that the command should
|
|
|
+ * use bytes.
|
|
|
+ *
|
|
|
+ * Valid characters are:
|
|
|
+ *
|
|
|
+ * b - byte
|
|
|
+ * w - word (16 bits)
|
|
|
+ * l - long (32 bits)
|
|
|
+ * q - quad (64 bits)
|
|
|
+ * s - string
|
|
|
+ *
|
|
|
+ * @arg: Pointers to the command to check. If a valid specifier is present it
|
|
|
+ * will be the last character of the string, following a '.'
|
|
|
+ * @default_size: Default size to return if there is no specifier
|
|
|
+ * @return data size in bytes (1, 2, 4, 8) or CMD_DATA_SIZE_ERR for an invalid
|
|
|
+ * character, or CMD_DATA_SIZE_STR for a string
