99 DFU transfer uses a buffer before writing data to the
100 raw storage device. This value can be used for setting the
101 size of this buffer. The size of the buffer is also configurable
102 through the "dfu_bufsiz" environment variable. If both are
103 given the size of the buffer is set to "dfu_bufsize".

108 help
109 When updating files rather than the raw storage device,
110 we use a static buffer to copy the file into and then write
111 the buffer once we've been given the whole file. Define
112 this to the maximum filesize (in bytes) for the buffer.
113 If undefined it defaults to the CONFIG_SYS_DFU_DATA_BUF_SIZE.
