The bootloader API calls this function whenever it outputs a word
|
|
to the bootloader hardware chain.
|
|
|
|
Because the API has no information about how the bootloader
|
|
hardware is connected to the host hardware, the user must
|
|
implement this function to write a word to the bootloader's register.
|
|
|
|
A user's implementation might write the bytes to an Xtensa queue or
|
|
to a memory-mapped register.
|
|
|
|
For example, xt-load uses this API just like any other client. Its
|
|
implementation of this function simply writes this word to an
|
|
output file.
