David Woodhouse 50515af207 firmware: Correct dependency on CONFIG_EXTRA_FIRMWARE_DIR
When CONFIG_EXTRA_FIRMWARE_DIR gets changed, the filename in the .S file
(which uses .incbin to include the binary) needs to change. When we
renamed the BUILTIN_FIRMWARE_DIR option to EXTRA_FIRMWARE_DIR, we forgot
to update the manual dependency in firmware/Makefile, so it was
depending on a non-existent file in include/config/

Jaswinder Singh fb54be8755 vicam: use request_firmware()
Although it wasn't actually using ihex records before, we use the Intel
HEX record format for this firmware -- because that gives us a simple
way to split it into separate chunks internally as we need, without
loading each part as a separate file.

David Woodhouse 27d202fff1 firmware: convert Ambassador ATM driver to request_firmware()
Since it had various regions to be loaded to separate addresses, and it
wanted to do them in fairly small chunks anyway, switch it to use the
new ihex code. Encode the start address in the first record.

David Woodhouse 59890f74e5 ihex: Add support for long records to ihex2fw.c
Some drivers could do with using records like Intel HEX, but with each
record being larger than 256 bytes. This has been possible in the binary
representation (struct ihex_binrec) in the kernel since the beginning --
at least of the the current version of history. But we haven't been able
to represent that in the .HEX files which get converted to .fw files.

This adds a '-w' option to ihex2fw to make it interpret the first _two_
bytes of each line as the record length, instead of only one byte. And
adds makefile rules for %.H16->%.fw which use that.

David Woodhouse 8bd6b2229b ihex: add ihex2fw tool for converting HEX files into firmware images
Not the straight conversion to binary which objcopy can do for us, but
actually representing each record with its original {addr, length},
because some drivers need that information preserved.

Fix up 'firmware_install' to be able to build $(hostprogs-y) too.

David Woodhouse 88ecf814c4 firmware: Add firmware installation to modules_install, add firmware_install
For 'make modules_install', install any firmware required by
the modules which are being installed.

Also add a 'make firmware_install' target which doesn't depend on the
configuration, but installs _all_ available in-kernel-tree firmware into
$(INSTALL_FW_PATH), which defaults to /lib/firmware. This is intended
for distributors to make arch-independent (and config-independent)
packages containing firmware.

David Woodhouse d172e7f5c6 firmware: Add CONFIG_FIRMWARE_IN_KERNEL option.
This will control whether we build firmware into the kernel image for
_every_ driver which we convert to request_firmware(), to avoid a
proliferation of 'CONFIG_XXX_FIRMWARE' options for each one.

Default to 'y' for now, which is the wrong thing to do but people seem
to be insisting on it and refusing to even review patches until it's
done. And it does preserve the existing behaviour for built-in drivers.
