We used to have opencoded ehci_readl()/writel() which required no external functions to be called. Now with attempt to switch to generic readl()/writel() accessors we see a missing declaration of those accessors in ehci-ppc4xx. Something like that happens if applied http://patchwork.ozlabs.org/patch/726714/: ---------------->8--------------- CC drivers/usb/host/ehci-ppc4xx.o drivers/usb/host/ehci-ppc4xx.c: In function 'ehci_hcd_init': drivers/usb/host/ehci-ppc4xx.c:23:3: warning: implicit declaration of function 'readl' [-Wimplicit-function-declaration] HC_LENGTH(ehci_readl(&(*hccr)->cr_capbase))); ^ ---------------->8--------------- Signed-off-by: Alexey Brodkin <abrodkin@synopsys.com> Cc: Tom Rini <trini@konsulko.com> Cc: Marek Vasut <marex@denx.de> Cc: Stefan Roese <sr@denx.de> Reviewed-by: Stefan Roese <sr@denx.de>
