Subject: [PATCH v2 00/10] firmware_loader: built-in API and make x86 use it
Date: Thu, 21 Oct 2021 08:58:33 -0700	[thread overview]
Message-ID: <20211021155843.1969401-1-mcgrof@kernel.org> (raw)

From: Luis Chamberlain <mcgrof@kernel.org>

Changes in this v2:

 o drops two patches which Greg has already merged
 o drop one patch which added the new kconfig symbol FW_LOADER_BUILTIN
   which Greg didn't like, and so instead we rely only on the FW_LOADER
   symbol. If anyone cringes during review because of this, just keep in mind,
   *this* is *why* I added the symbol in the first patch series.

I've ran the firmware selftests test and found no issues. I have also
let 0 day grind on this and it found no issues. This is all based on
linux-next next-20211020, I have a branch 20211020-firmware-builtin
which has these changes in case anyone wants this in a git tree [0].

  firmware_loader: move struct builtin_fw to the only place used
  vmlinux.lds.h: wrap built-in firmware support under FW_LOADER
  x86/build: Tuck away built-in firmware under FW_LOADER
  firmware_loader: rename EXTRA_FIRMWARE and EXTRA_FIRMWARE_DIR
  firmware_loader: move builtin build helper to shared library
  test_firmware: move a few test knobs out to its library
  test_firmware: add support for testing built-in firmware
