[PATCH] [RFC] USB: fsl_udc_core: fix build-failure for ARM

[Uwe Kleine-König]

Commit

	09ba0de (USB: fsl_udc_core: prepare for SoCs with BE registers and descriptors)

introduced two function pointers _fsl_readl and _fsl_writel in an #ifdef
CONFIG_PPC32 block and used then unconditionally in fsl_udc_probe.
To make the driver compile again this use has to be protected by
an #ifdef, too. Moreover ARM doesn't have flush_dcache_range so this
is #ifdefed out, too.

Hello,

I'm unsure about getting rid of the flush_dcache_range. If powerpc needs
a flush ARM probably does, too, no?
If so, what it the right thing to do? Implement flush_dcache_range for
ARM (just wrapping flush_dcache_page?)?

Best regards
Uwe
