This is part of the documentation included later in this patch. I can add
this to the changelog.

+Some devices load firmware from on-board FLASH when the card initializes.
+These cards do not require the request_firmware framework to load the
+firmware when the card boots, but they to require a utility to allow
+users to update the FLASH contents.

When you say "existing firmware api", I'm thinking request_firmware, which
requires that driver names be specified in the kernel config and wants to
load firmware automatically during device initialization.

Other support under driver/firmware is specific to certain vendors, devices.

If I add this information to the changelog, is that sufficient?
