      ihex: add support for CS:IP/EIP records · 2473238e
      Mark Brown authored
      
      ihex firmwares can include a jump address for starting execution.  Add a
      -j option which will cause this to be written into the generated file as a
      record with address zero and data consisting of the address to jump to,
      allowing drivers to make use of this information.
      
      This format is chosen because it most closely follows the original ihex
      format, though it may make more sense to write a record with length zero
      and the address stored as the address.  The records are not omitted by
      default since our ihex format does not include record type information and
      so including additional records may lead to confusion.

      radeon: Use request_firmware() · 70967ab9
      Ben Hutchings authored
      
      Loosely based on a patch by
      Jaswinder Singh Rajput <jaswinderlinux@gmail.com>.
      
      KMS support by Dave Airlie <airlied@redhat.com>.
      
      For Radeon 100- to 500-series, firmware blobs look like:
          struct {
              __be32 datah;
              __be32 datal;
          } cp_ucode[256];
      
      For Radeon 600-series, there are two separate firmware blobs:
          __be32 me_ucode[PM4_UCODE_SIZE * 3];
          __be32 pfp_ucode[PFP_UCODE_SIZE];
      
      For Radeon 700-series, likewise:
          __be32 me_ucode[R700_PM4_UCODE_SIZE];
          __be32 pfp_ucode[R700_PFP_UCODE_SIZE];
