lspci on R40e gives the IDE Interface

00:0f.0 IDE interface: ALi Corporation M5229 IDE (rev c4) (prog-if fa)
	Subsystem: IBM: Unknown device 053d
	Control: I/O+ Mem- BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr-
Stepping- SERR- FastB2B-
	Status: Cap+ 66Mhz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort-
<TAbort- <MAbort- >SERR- <PERR-
	Latency: 0 (500ns min, 1000ns max)
	Interrupt: pin A routed to IRQ 0
	Region 4: I/O ports at 8080 [size=16]
	Capabilities: [60] Power Management version 2
		Flags: PMEClk- DSI- D1- D2- AuxCurrent=0mA
PME(D0-,D1-,D2-,D3hot-,D3cold-)
		Status: D0 PME-Enable- DSel=0 DScale=0 PME-


In the linux kernel I select Ali M15x3 chipset support which provides
the IDE controller for M5229.

Snip from dmesg

ALI15X3: IDE controller at PCI slot 0000:00:0f.0
ALI15X3: chipset revision 196
ALI15X3: not 100% native mode: will probe irqs later

    ide1: BM-DMA at 0x8088-0x808f, BIOS settings: hdc:DMA, hdd:pio
