MPC8xxx: Define cache ops for USB
This patch conditionally defines flush_dcache_range() and invalidate_dcache_range() on MPC8xxx, to avoid EHCI complaining, resulting in the following output: $ ARCH=powerpc CROSS_COMPILE=powerpc-linux-gnu- ./MAKEALL MPC8572DS Configuring for MPC8572DS board... make: *** [u-boot] Error 1 powerpc-linux-gnu-size: './u-boot': No such file e1000.c: In function ‘e1000_initialize’: e1000.c:5264:13: warning: assignment from incompatible pointer type [enabled by default] tsec.c: In function ‘tsec_initialize’: tsec.c:638:12: warning: assignment from incompatible pointer type [enabled by default] drivers/usb/host/libusb_host.o: In function `ehci_td_buffer': /home/marex/U-Boot/u-boot-imx/drivers/usb/host/ehci-hcd.c:186: undefined reference to `flush_dcache_range' drivers/usb/host/libusb_host.o: In function `ehci_submit_async': /home/marex/U-Boot/u-boot-imx/drivers/usb/host/ehci-hcd.c:346: undefined reference to `flush_dcache_range' /home/marex/U-Boot/u-boot-imx/drivers/usb/host/ehci-hcd.c:348: undefined reference to `flush_dcache_range' /home/marex/U-Boot/u-boot-imx/drivers/usb/host/ehci-hcd.c:349: undefined reference to `flush_dcache_range' /home/marex/U-Boot/u-boot-imx/drivers/usb/host/ehci-hcd.c:372: undefined reference to `invalidate_dcache_range' /home/marex/U-Boot/u-boot-imx/drivers/usb/host/ehci-hcd.c:374: undefined reference to `invalidate_dcache_range' /home/marex/U-Boot/u-boot-imx/drivers/usb/host/ehci-hcd.c:376: undefined reference to `invalidate_dcache_range' /home/marex/U-Boot/u-boot-imx/drivers/usb/host/ehci-hcd.c:386: undefined reference to `invalidate_dcache_range' make: *** [u-boot] Error 1 --------------------- SUMMARY ---------------------------- Boards compiled: 1 Boards with errors: 1 ( MPC8572DS ) ---------------------------------------------------------- Signed-off-by: Marek Vasut <marex@denx.de> Cc: Wolfgang Denk <wd@denx.de> Cc: Anatolij Gustschin <agust@denx.de>
