Align these files with the upstream kernel: t4_chip_type.h t4_pci_id_tbl.h This also fixes the incorrect copyright headers in the libcxb4 versions of these files. Signed-off-by: Steve Wise <swise@opengridcomputing.com>
Pull the upsteam kernel t4_regs.h and make the needed src changes for the different macro names. This also fixes the copyright, which is driving this work. Signed-off-by: Steve Wise <swise@opengridcomputing.com>
Upstream has 2 header files that map to t4fw_interface.h, so pull them in and make the needed changes. Also remove t4fw_interface.h. This fixes the copyright, which is driving this work. Signed-off-by: Steve Wise <swise@opengridcomputing.com>
